1. > > > > Watcher's Keep (AR 3000)


 Note:  Most of the good items found in Throne of Bhaal are located right here
        in the Watcher's Keep. (and many can be made even better by your
        abyssal butler, Cespenar)
        Also, if you start the expansion right away, you'll be taken to the
        next section, the Forest.  Watcher's Keep is listed first since it
        can be accessed from the regular game as well.
 Walkthrough:
 ------------
   - A MYSTERIOUS KEEP
     Go up and talk to "Brother" Ordren, who explains the whole sticky
     situation to you.  Helm has sealed some great and powerful evil in the
     Watcher's Keep, that is gradually getting free.  It is your job to enter
     the Keep and prevent the Evil from getting out.  Oh, and they tell you
     specifically NOT to kill it, as Helm has forbidden it.  Agree to help
     them and they'll take you to the top (Level 1).  They give you what
     you will need, and bid you good luck.
     Talk to Brother Pol to get the Holy Symbol and the Scroll.  These items
     are needed.  When you reach the evil, you are to perform a ritual to
     deal with it.  You don't kill it.
     At this point, you can talk to them again and ask questions, or talk to
     the Sister to buy items and so forth.
       Note:  Two of the items that she sells, Firetooth +4 and the Short
              Sword of the Mask are items that can be upgraded by your
              abyssal servant Cespenar (if you haven't gotten your Pocket
              Plane, the Abyssal Fortress, then you won't know what I'm
              talking about).
     When you're ready, enter the Keep.
   - LEVEL ONE (AR 3001)
     The difficulty of the keep depends on several things, your preset
     difficulty level, the number of people in your party, your level, and
     your experience.  The puzzles don't get any easier on the other
     difficulty modes... if you're wondering.
     The entrance to the next level is the Mirror Portal (x 1450 y 1150),
     however there are quite a number of things that must be done first.
       Note:  There are many traps on this level, most are attached to the
              various containers, although there are 2 traps on the ground.
     Open the left door to find the ghost Archivist. (x 1925 y 1860)  Talk to
     him, but he is simply Cold.  We'll have to remedy that.  There are 4
     containers in this room, 2 are trapped.  Take whatever treasure you want,
     but be sure to get the:
       Paladin's Bracers (+10 HP, paladins only, upgradeable by Cespenar)
     The next room had a Stone Golem in it.  Not too tough.  Open the next
     door (x 1530 y 2010) and enter a library type room.  There will be some
     monsters here.  The shelves on the right side have some Notes with Clues.
     Also note Elminster's Ecologies (there's one in the next room as well),
     which explain some of the properties of the new Monsters.  Be sure to
     check the shelf at (x 1330 y 1590) for the wonderful:
       Golem Manual (creates Flesh Golems, upgradeable by Cespenar)
     Also check the Treasure chest near the end of this room for more treasure
     and another note.  Open the next door (x 888 y 1574) and proceed.
     Yes, that statue is watching you.  There are 3 containers in here, and
     the one at (x 625 y 1140) is trapped:
       Case of Plenty +1 (unlimited +1 bolts, upgradeable by Cespenar)
     You need to get the Bell at (x 450 y 1250).
     The final container in this room, a trapped chest (x 775 y 1200)
     contains:
       Crimson Dart +3 (returns to owner)
       History of the Imprisoned One (in case you're curious)
       Potion of Superior Healing
       Chainmail +2
       more treasures...
     Open the door to the right (x 840 y 1220) and go through.  Depending on
     your level, there will be all sorts of statues in this, the central
     hall.  Worry about it later, go up to the door on the left side (x 670
     y 900).
     Get the Candle in the chest by the fireplace (x 340 y 1050).  There are
     other minor treasures in here, and a fireplace.  Go back.
     Across the hall, enter the middle door (x 1620 y 865).  This room has
     several traps on the floor, so beware.  Also, of the 4 containers in here
     2 are trapped.
     Get the Slippers from the left shelf (x 1550 y 750).
     The trapped armoire (x 1840 y 600) has:
       Quiver of Plenty +1 (unlimited +1 arrows, upgradeable by Cespenar)
       Handwritten Note
     The trapped alcove (x 1980 y 580) has:
       Ammo Belt (actually a container that holds arrows, bolts, etc.)
       Tinderbox (if only we had a fireplace... wait a second!)
     Open the lower door and enter another library.  Kill anything moving in
     here (I got spiders).  Search the shelf at (x 2240 y 920) to find:
       Wardstone
     The other shelf in here has a Potion of Superior Healing.  Open the next
     door and hit the almost-final room.
     Search the Armoire (x 2775 y 1210) to find:
       Wardstone
       Potion of Superior Healing
     The other container, a shelf, has the final Tattered Parchment, if you're
     curious.  Open the door to the left and hit the final room.
     Search the armoire by the door (x 2610 y 1485) for:
       Key
       4 Potions Extra Healing
       King's Tears
     The table has a Handwritten Note.  Go back to the large hallway.
     Almost ready to do the ritual.  Go back to the Fireplace room, and click
     on the fireplace to light it (Tinderbox...).  This summons the Archivist
     who is now quite conversant.  He'll tell you about the old Priest, and
     a little about how to reach the next level.
     Open up the large door on the top of the right side (x 1375 y 730).
     Enter.  This is the burial place of the High Priest, complete with
     Guardian Golems.  The alcove over to the left (x 1040 y 430) has the
     final Handwritten Note.  When you're ready, click the Sarcophagus to
     open it.  The golems come alive, and attack you.  They're each worth
     13,000 experience.  Open the Sarcophagus.
     This causes the resident of the tomb to arrive and chide you for waking
     him up.  He notices that you have his slippers, and asks for them.  Give
     them up.  This is worth 20,000 quest experience, and he leaves you alone
     to your graverobbing.  Click the Sarcophagus one last time to get the
     Mental Note.  This is worth 8,000 quest experience.
       Note:  If the guardians DON'T come alive, you can always force-attack
              them later.
     Back to the main hallway.  Go up to the altar at the top of the room,
     open it and place the Bell and Candle in it.  When that is done, the
     statues come alive and attack you.  Destroy them.  When the statues that
     came alive are dead, the giant statue talks to you and asks for the
     ritual:
       Ring the Bell
       Ring the Bell
       Light the Candle
       Open the Book (only works if you opened the Sarcophagus)
       Ring the Bell
     That completes the ritual, and opens the Mirrored Portal to the next
     level.  This is worth 25,000 quest experience.  At this point, the rest
     of the statues came alive and attacked me.  This was a much more
     difficult battle, and you should definitely take care of the mages first.
     Also they had some interesting equipment:
       Usuno's Blade +4 (scimitar)
       Foebane +3 (Bastard Sword, upgradeable by Cespenar)
     Whenever you are ready, go on down.  This requires that you got the Vigil
     Stone from Pol.  If you don't have it, exit and talk to Pol to get it.
       Note:  If you want to rest (and this would be a good time), go to the
              Protected Room in the right corner.
   - LEVEL TWO (AR 3016)
     As you appear, a Chromatic Demon talks to you.  He is the only thing that
     can get you to the next level, but he won't do that until you do a little
     something for him.  He has been trapped in this place for a thousand
     years and it isn't where he thought his life was heading.  Naturally he
     wants your help in getting out.  Sounds fair.  He needs you to get him
     out of his cage.  Agree to it.  You need to find the Four Scepters and
     place them in the slots around his cage.  Only then will he allow you
     entrance to the next level.
       Note:  If you want to go back, use the Portal to the Left.
              Also, beware of Traps!  They're everywhere.
     Enter the room to the southwest (x 1670 y 1850).  Careful in here, there
     are many traps on the floor and containers.  Detrap the room.  Time to
     search for treasure, and clues.
     The top right shelf (x 1600 y 2130) has a Handwritten Note.
     The top left shelf (x 1325 y 1925) has:
       Wand of Spell Striking
       Star Sapphire
     The small shelf (x 1000 y 2110) has some good stuff:
       Right Horn (used by Cespenar)
       Ice Library Note (a Clue!)
     Read the Ice Library Note to learn how to clear out the Fire room.
     Essentially you need to deal with the Fire Elementals first, but you
     can't just kill them or they'd respawn, they must be lured into the Ice
     Room and frozen there forever.
     There are other minor treasures in here as well.
     Back to the center room, now take the upper left (northwest) door (x 1700
     y 1350).  There are some Fire Giants in here that need killing.  This
     place also has many traps to be dealt with.  Enter the room.  You'll find
     an imp in the upper passage here.  He'll tell you that the Fan is the
     key to everything before leaving.  Time to search the room.
     You'll find a Handwritten note on a table (x 1130 y 860).
     The top of the pillar (x 1260 y 760) has:
       Wand of Cursing
       5 Potions of Superior Healing
       more treasures...
     Search the small shelf (x 1370 y 870) to find:
       Fire Library Note (another Clue!)
     There are other minor treasures in here.  On to the next room (x 2420
     y 1350).
     This room is filled with various types of Golems.  It is again trapped
     quite thoroughly.
     The Handwritten Note is at (x 3210 y 1000).
     The Air Library Note is at (x 3000 y 900).  This note mentions how you
     might clear out the poison room, and the usefulness of lightning when
     dealing with the new slimes found therein.
     Nothing much else here, go down to the final room (x 2425 y 1840).  Here
     you must deal with some Mutated Spiders.
     Search the shelf to the right (x 2900 y 1900) to find:
       Key
       other treasures
     Search the far right shelf (x 3225 y 2120) to find:
       Slime Library Note (the last Clue!)
       5 Potions of Extra Healing
     Read the final note to learn that the demon's Air form is weak against
     poison and acid.  Also you'll learn how to set the fan to blow poison
     from the Slime Room into the Air room to kill weaken the creatures there.
     We have everything we need, time to make the most of it.
   - LEVEL TWO, GAINING THE FOUR SCEPTERS
     To get to the Fan Room, go into the Red Room (upper left), and up to the
     door (x 1800 y 675) where the Imp was.  Go in and turn the fan.  This
     will get you attacked by several Air Elementals.  Kill them to get the:
       Air Scepter
     Go up to the fan and click it again to get more air going.  This allows
     you to open the door to the right, into the Slime Library.  From there
     continue going down-right and open the next door into the Slime Room.
     This room is filled with noxious vapors, and lots of slime/poison related
     monsters.  Quickly open the bottom door in this room to clear it of all
     its poison.  Kill the snake to get:
       Slime Scepter
     Also, search the pool of slime to get:
       Flail Head (Poison, Cespenar can upgrade the Flail of Ages with this)
       Note:  Getting too close to any of the "pools" results in damage taken.
              In the slime room you get Acid Damage, for instance.
     Head down to the next, icier door (x 2350 y 2500) and open it.  Now,
     run back to the Fan Room, click the Fan control once to reset it, and
     click it again to shoot the poison from the poison room into the Ice
     Room.  Sweet.
     Go back to the Ice Room and kill the monsters there.  The poison didn't
     bother me too much, but you could just stand at the edge of it and attack
     from there.  When the Ice Golem dies you get the:
       Ice Scepter
       Left Horn (used by Cespenar)
       Note:  To clear the room of poison, just click the Fan again.  Also,
              the Ice Room has a slowing effect.
              I'd leave all of your party (save one) in the Ice Room.
     Open the door to the left, go through the library and up to the next
     door.  Open that.  Enter the room, avoid the giant.  Wait for a Fire
     Elemental to appear, then lead it back into the Ice Room, for your
     waiting party to kill.  Wait for the Elemental to FREEZE (there will even
     be some text to this effect), then attack.  The elemental shatters,
     letting you know you've succeeded.  Do this for 4 elementals (it doesn't
     have to be all at once, or one at a time, just lure as many as you can).
     Doing that gets you 22,000 experience.
     When that is done, go up and kill the Fire Giant:
       Fire Scepter
       Helm of the Rock (+25% fire, ice, elec. res., upgradeable by Cespenar)
       100 gold
     You now have all 5 scepters.  I'd rest, save, then go talk to the Demon.
     Everyone gets 20,000 experience, and he, of course, attacks you.  Who
     saw that coming?
       Chromatic Demon  -5 AC  140 HP  -5 THAC0  4 Attacks  95% weapon res.
     Your weapons will damage him, but they just won't do much damage.  As he
     is damaged, he will switch forms.  Just remember what each form is weak
     against...
       Red Demon        >  Ice
       Ice Golem        >  Fire
       Shambling Mound  >  Lightning
       Air Elemental    >  Poison
     If you're in ToB, this is an easy enough fight, buff-up beforehand, 
     keep the fighters in the front and use whirlwinds. Three or four fighter
     types doing 10 hits/round at 4 damage a hit should knock it down fast.
       Tip:  After you have all 4 scepters, but before you free the Chromatic
             Demon, close the lower door in the poison lab. Then turn off the
             fan in the air lab so the poison lab is full of gas. Move all but
             one of your party members out of the way (the fire library works
             nicely). Then have your remaining character (preferably having
             them hasted first) release the Chromatic Demon. Lure the
             Chromatic Demon into the poison lab (via the air library), then
             exit the poison lab into the air library, closing the door behind
             you and trapping the Chromatic Demon in the poison lab. Then just
             sit back and wait for the Chromatic Demon to die. It doesn't take
             long. (Jeremy Hanson)
     When he is dead...
       55,000 experience
       Circlet of Netheril (Cespenar can upgrade)
       Portal Key
       Ixil's Spike (+2 dagger, Cespenar can upgrade)
     Whenever you're ready, enter the right portal to the Next Level.
   - LEVEL THREE (AR 3003)
      N    E
       \  /      Ooh, Isometric!
       /  \              
      W    S 
     Our informer on this level is a crazy elf named Yakman.  When you talk to
     him he becomes convinced that you are some demonic illusion out to kill
     him, causing him to run away.  Follow him through the portal (x 1350
     y 1100) and try talking to him again.
     (AR 3011)
     There is a pile of stuff (x 615 y 630) in the middle of the room:
       Bard's Gloves (Cespenar can upgrade)
     There is more treasure up in his tent (x 860 y 360, TRAPPED):
       Madman's Journal (a Clue!)
       Diamond
       Long Sword (you may want to take this... seriously)
       Scepter of Radiance (you definitely need to take this)
       other treasures...
     Once you're done looting, talk to Yakman.  You need someone with 16 or
     more Charisma, or an Elf to get him to trust that you aren't an
     illusionary demon.  Ask all the questions you can, about the Demons,
     why they fight each other, the level, the way out, the rod and its
     gems, etc.  Next tell him he needs some sleep, to learn that he never
     sleeps.  Offer to heal him, and the conversation ends. (the character
     who spoke to him MUST be a cleric for this offer to come up)
     Cast Heal on him and he is back to normal... although you might prefer
     the insane version (he's quite arrogant).  This gets you 5,000 quest
     experience points.  With that he exits the Watcher's Keep to find out if
     he can restore his old life.
     Enter the top portal (x 380 y 350) to return to the previous area (the
     other portal takes you back to the beginning).
       Note:  Resting anywhere in this maze will get you attacked by Succubuses
              (er...), Glabrezu or other types of demons, which makes this a 
              great place to get experience, as they give between 6000 exp and
              24,000 exp each. (Later you fight devils, but they're not as much
              fun)
 
     (AR 3003)
     Head into the East Portal.
     (AR 3008)
     There will be various demons fighting amongst themselves here.  They
     mention the Blood War (see: Planescape: Torment).  Kill the demons here.
     (pretty easy to do since they're fighting each other)
     Have someone of a lawful good alignment click on the Pillar to get: (evil
     people get Horridly Wilted)
       Purifier +4 (Bastard Sword, Upgradeable by Cespenar)
     Go "east" again (x 1070 y 150).
     (AR 3012)
     Here you are confronted by a Tanar'ri.  If you are evil, you can side
     with it.  It will want you to kill its enemy Ka'rashur.  If you are Good
     you will have no choice but to kill it.  From its body, take the Scepter
     Gem.
       Note:  When you return with the Heart of Ka'rashur he gives you the
              mighty Thieves Hood (useless until Cespenar upgrades it). This is
              the ONLY way to get this item, he won't have it on him if you
              kill him.
     There is a trapped alcove (x 650 y 320) with some treasure.
     Head on down "south" to the portal at (x 880 y 720).
     (AR 3004)
     This is a "no magic" zone.  Kill off the demons in the area.  Also there
     are traps on the ground where the 4 hallways meet the center room. You'll
     have to pass one to fight the monsters.
     Go "south" again (x 1350 y 1100).
     (AR 3006)
     Welcome to the Succubus area.  Whee.  They'll attempt to tempt you, but
     don't bother with them.  Of course, if you turn them down, they attack
     you.  Ah well, demons just can't be reasoned with, I guess.
     Head through the south gate.
     (AR 3013)
     Here you'll find the Baatezu (the very same ones that you were asked to
     kill by the Tanar'ri earlier).  If you're evil you can side with them,
     otherwise prepare for a fight.
     Be sure to search the corpses for the second Scepter Gem.
     There is a small container (TRAPPED, x 960 y 360) above.  It has some
     minor treasures.
     Again, use the lower portal.
     (AR 3010)
     There are some Glabrezu lurking around here.  Also, if you go back
     through the portals you entered from, you'll get back to the beginning.
     We want to take the "western" portal, so head down and left to (x 150
     y 785).
     (AR 3005)
     We experienced a "no-magic" room earlier, now we have entered a
     "wild-magic" room.  Here, magic just doesn't work as you might expect,
     much like the "wild surge" effect you get if you play as a Wild Mage.
     There are some Tieflings in here, but they aren't important.
     Here's a twist, re-enter the portal you just came from (the "north"
     portal).
     (AR 3007)
     There's a Cambion in here, but you don't have to deal with him.  If you
     do fight him, he'll summon several demon knights to help out.
     Again, like the last area, re-enter the portal you entered from (the
     "north" portal).
     (AR 3014)
     Right out of the portal are some really deadly traps.  Try to disarm them
     before engaging in battle.
     Here you must fight a Demon Wraith and his armies of the undead.  Kill
     him.
     There are lots of minor treasures in here.  There is also a really
     good item as well:
       (x 340 y 640) - White Dragon Scales (Cespenar can make armor of these)
     Again, take the portal you came out of (the "north" portal).
     (AR 3015, the "Exit")
     This is more or less where you would have been taken if you got abducted
     by a Succubus.
     Just for arriving here, you get 10,000 quest experience.
     When you first appear here, you'll find Aesgareth confronting you.  He's
     not from around here.  He also has the necessary Scepter Gem in order
     for you to move to the next level.  That is not of the moment.  Be civil
     to him, but don't reveal that you have a possible way out.  He wants to
     play cards with you, the stakes being the Scepter (essentially).  Agree
     to it.  The conversation ends so you can "prepare."
       Note:  Sounds like your cue to SAVE THE GAME.  If you lose the game,
              reload.  After winning, save it again.
              Also... You can pick-pocket Aesgarth for the deck of many
              things during the "Let me think about it" time. Your pick-
              pocketing skill should be at least 150+ though. (Xander77)
     Talk to him again.  The game involves attempting to survive whatever the
     Deck of Many Things hurls at you.  The stakes are, for him the Scepter
     Gem, a Wish Scroll or a Spectral Brand, and you get to pick:
         Note:  The Spectral Brand (Long Sword +4) is upgradeable by Cespenar.
       The Way Out (The Vigil Stone)... wager this!
       Experience
       Vitality
         Note:  If you get the strength card and lose your Strength, use a
                Remove Curse spell to dispel it. (thanks to Doug Scheurich)
     You win by picking the "higher" card, which usually means the "worse"
     card!  Winning a game is worth 25,000 quest experience.  If you win the
     first two games (for the Spectral Brand and Wish scroll), talk to him
     again and get an instant 20,000 quest experience.
     Try to get the Spectral Brand if you can.  Even if you lose the draw,
     Aesgareth will return the Vigil Stone to you (so you don't lose anything)
     and even give you the Scepter Gem to boot!  What a nice demon.
     For completing this you get 25,000 quest experience.
       Note:  The maximum experience playing the game is 95,000 quest
              experience.  Remember quest experience is NOT divided among
              the party, everyone gets that exact amount. (when you kill a
              1000 exp monster, on the other hand, it is divided amongst
              everyone in the party)
       Alternatively:  You could be hostile and attack him.

                       so if you have 6 people, each person gets 17,500 exp)
                       Also, it is possible to win the first two games, then
                       lose the last game, and fight him then.  You still get
                       less Exp for killing him than letting him go.

     Time to get out of this maze.  Before leaving this level, prepare for a
     battle with Mind Flayers.  Cast some protective magics on sensitive
     players, Haste, etc.  Enter the right portal.
   - LEVEL FOUR (AR 3017)
     Watch as a mage (MAD mage) forces some giths and illithids to fight a
     battle.  Then you get to talk to him, but this proves to be quite
     unfruitful as he simply sends some goons to attack you. (In my case, it
     was Illithids)
     Up above the machine, there are four large containers (x 3300 y 1550).
     Besides having the normal assortment of minor magical items, they also
     carry NON-magical items.  You might want to take some, you're going to
     need them.
     Open the door near here (x 3600 y 1660) and enter this room.  There are
     2 containers upwards, both are locked, the one on the left is trapped.
     They have only minor treasures.  There's another locked chest at the
     lower end of this room with more minor treasures.
     Open the next door (x 4100 y 1300) to find the Magical Golems.  These
     guys can be hurt ONLY by non-magical weaponry (hence the shelf full of
     that stuff), so be sure that everyone is equipped with something mundane.
     However, once you have normal weapons equipped, these golems are
     pushovers.
     Enter their room, and search the giant Pool to get some Blue Oil.
     The three containers (the middle one is trapped) at the top of this room
     have more minor treasures.
     Back to Carston's Room.  This time, take the door to the south (x 2600
     y 2300)
     The container just to your south (x 2850 y 2600) has a large variety of
     healing potions.
     The treasure chests at the top of the room are not treasure chests at
     all, but Killer Mimics that attack you.  Once the mimics are dead, you
     can search the containers for more minor treasures.
     The final door (x 2130 y 2670) leads to several torches, which you can't
     light just yet.  Back to Carston's room.  Head up to the top stairs
     (x 2400 y 1500).  You'll be fighting more Mind Flayers, so be ready.
     Go down.
     (AR 3021)
     Once here, I summoned a Mordenkainen's Sword, and sent it down.  The
     enemies all attacked that (quite uselessly) allowing me to swoop in
     behind them and slaughter them.
     Open the door to the left, and go down the passage to a small circular
     room.  There were some Umber Hulks here that wanted to be killed.  Once
     they're dead, search the circular thing in the center for:
       Illithid Rod
       Wand of Cursing
       other treasures...
     Go back, then open the lower door and enter that room.  There are more
     Hulks and Illithids in here to be killed.
     Search the table at (x 1600 y 915) for:
       5 Potions of Extra Healing
       Handwritten Note
       other treasures...
     Open the cell door, and search the table in there for more small
     treasures.  Also the table to the right has more treasures, healing
     potions, etc.
     Enter the right cell and talk to the dying Apprentice.  Ask him about
     Carston and the exit to the next level.  The key is the Machine, of
     course.  He dies, and you can then search the table behind him for more
     small treasures.  For helping him die (I guess) you get 1000 quest
     experience.
     Open the southern door, and go down the passage to another circular
     room.  There are 3 illithids in here and some Umber Hulks.  Kill them.
     One of the illithids has the second part of the Illithid Rod key, once
     you get it you get 4000 experience and the completed key.  The container
     in the center of the room here is TRAPPED and has minor treasures.
     Go back up to the cell room, then left (x 1200 y 1000).
     This is the Red Oil Room.  When you take the red oil from the vat you
     will be attacked by a couple of Vampiric Illithids (the best of BOTH
     worlds there).  They're each worth 14,000 experience.
     Head back up to Carston's level.
     (AR 3017)
     Drop down to the lower stairway (x 4000 y 2600) and go down.
     (AR 3022)
     If you thought that the Gith might be more reasonable than the Illithid
     were, well you're wrong.  They're not.
       Note:  Some of these Gith are considered to be Anti-Paladins.  Don't
              you wish that you could be an Anti-Paladin?
     There are 3 chests in this first room, and the "middle" one is trapped.
     They mostly have minor treasures with one exception...
     Be sure to get the Flint and Tinder from the lower chest (x 880 y 550).
     The door to the right has more Giths and some minor treasures.
     Open the lower-left door and go through (x 900 y 800).
     Fight off the Giths in this room, then search it for treasure.  There is
     another Handwritten Note here at (x 400 y 950).
     Open the door in the lower right (x 900 y 1200) to go to the next room.
     You'll have to fight through a wave of Gith, but if you can take on the
     Illithids, the Gith should present no problems at all.  When they're
     dispatched, go further to the right to find the captain.  You can't talk
     him out of a fight, so don't bother trying.
       Captain - 7500 experience
                 Diary of Carston's Apprentice (a Clue!)
                 Angurvadal (Long Sword +4, upgradeable by Cespenar)
     Search the "teeth" of their ship (x 1350 y 1550) to find:
       Montolio's Clasp (part of Montolio's Cloak, upgradeable by Cespenar)
       other treasures...
     Search the purple pool (x 1550 y 1700) to get:
       Purple Oil
     Open the door in the bottom right corner here (x 1830 y 1960) and
     descend.
     (AR 3018)
     Follow this down to find a great red Dragon, Saladrex.  In case you're
     planning on attacking him (don't yet), here are his general stats:
       244 HP  -12 AC  -6 THAC0  3 Attacks  30% all weapon res.  64,000 exp
         Staff of the Ram +4 (Upgradeable by Cespenar)
         Rogue Stone
         1500 gold
         other treasures...
     Anyway, let's just have a pleasant chat with him for a bit.  You can
     attack later if you want.  Try to use the "flattering" answers whenever
     possible ("oh mighty Saladrex") as he is a very vain dragon.  Ask him
     what he's doing here, and he'll tell you that he was summoned by the
     Mad Mage Carston like everyone else, but he found that he liked it here.
     Depending on how flattering you were, you'll be able to ask him some
     questions.  Ask him everything that you want...
     Then, if you so desire, you can attack.  Most of the "trick" strategies
     for killing dragons that worked in BG2, no longer work (Fake Talk,
     tossing out Cloudkills, etc.), so you might actually have to prepare for
     a real fight.  I'd make sure to cast Resist Fear on everyone, as Dragons
     tend to be frightening.
       Tips:  Killed the dragon by using one of the many spell striking
              wands to lower its resistance (cast about 3 times), then
              used wand of lightning a bunch of times.  Used cleric to
              heal/cast resist fire/resurrect.  Important to note that the
              dragon in watcher's keep cannot fit through its big doorway,
              allowing you to stay out of range of all but it's fire
              breath.  Fun stuff.  If you're really crafty, you can grab
              some additional fire protections, and nix the cleric.  This
              method is mainly for those who go straight from Irenicus'
              Dungeon to Watcher's Keep.  (from Braden)
     Once you're done here, go back up.
     (AR 3022)
     Want to fight a Demi-Lich?  Whenever you've prepared, head over to the
     left, open the door (x 750 y 1850) and descend.
     (AR 3027)
     Nothing here, but a Demi-Lich!  I'd send in only one character and
     attempt to draw him out of his little hidey-hole.  I'd keep your mages
     WELL away from this battle so they can cast Freedom on anyone who happens
     to get imprisoned by him.  So, what I did was cast Simulacrum, and had
     that stay in the battle with me, and had my real mage go hide somewhere.
     I'd also send your main character away as well, this prevents him/her
     from getting imprisoned and ending your game.  Of course, if you have a
     Berserker in your party, just Berserk and hit him hard and fast.  
     Berserking makes you immune to imprison.
       Demi-Lich - 55,000 experience
                   Star Dagger +4 (upgradeable by Cespenar)
                   20,000 gold
                   other treasures...
     Be sure to check his coffin for more treasures.
     Go back to the Gith level, and from there back to the main Mad Mage
     level.
     (AR 3017)
     Head left to the torches (x 1680 y 2860).  There are 6 torches, 3 on the
     left and 3 on the right.  Here's the color coding...
       Red       Blue
       Red       Purple
       Purple    Red
     Click on each torch and light them according to the pattern. (You get
     the pattern from the tiles in the two side rooms, if you're curious...
     it's easier to see if you look at the mini-map)  When all the torches
     light, the door opens and everyone gets 10,000 quest experience points.
     Enter the last room.
     Here you must fight two Minotaurs, Rock and Garock.  Somehow they also
     summon other monsters to help them.  But after clearing out a dragon and
     demi-lich, what are 2 minotaurs?
       Rock - 15,000 experience
              Axe of the Unyielding +3 (Upgradeable by Cespenar)
              2 Potions of Superior Healing
              Battle Axe +3
       Garock - 10,000 experience
                2 Potions of Superior Healing
                Battle Axe +3
     Time to search the Vaults.  The left one is trapped, the right one is
     locked.
     Get the Crystal Mallet from the left vault.
     Be sure to get the Clay Golem page from the right vault.  The other
     treasure is decidedly minor.
     Head back to the great machine, and click on it.  You need to hit the
     thing SIX times in order to get Carsten out of it.  Once he is removed
     from his cocoon, he isn't quite as arrogant.  Let him live and he'll
     give you his journal.  You get 10,000 experience for letting him live.
     (He's worth only 6000 to kill)  Read his journal to learn how to activate
     the portal to the next level.  However, we have a machine to play with
     first...
     Save it first, then use the machine.  All the handwritten notes you have
     been gathering are the formulas for what you can do with it.  Each
     valid combination requires 3 switches/buttons/whatever to be pressed.
     They can be done in any order.  The bonuses work on whoever used the
     machine, not just the main character.  So, if you need your priest to
     gain some wisdom...
     Here is a complete list of the valid combinations:
        Triangle  Green   Medium    > Storm Star +3 (Cespenar can upgrade)
        Blue      Green   Long      > Gain Magic Res.
        Circle    Blue    Long      > +1 INT
        Square    Blue    Short     > +1 DEX
        Red       Green   Short     > +1 CHA
        Circle    Square  Triangle  > +1 WIS
        Circle    Red     Long      > +1 CON
        Square    Short   Medium    > +1 STR
        Triangle  Red     Medium    > Exit to next level
        Note:  You can only do the Stat bonuses ONCE.
     If you enter in an INVALID combination, you get some really bad random
     effects (well, mostly bad):
       10% chance to gain a Potion of Superior Healing.
       10% chance to get 100,000 experience (only for whoever used it)
       10% chance to become Imprisoned (bad if it's your main character)
       10% chance for 50 fire damage
       10% chance turned to stone (bad if it's your main character)
       10% chance to lose 1 INT
       10% chance for 75 lightning damage
       10% chance to be poisoned
       10% chance to lose 15 levels
       10% chance to lose 1 DEX
     Anyway, use the machine's Triangle, Red, Medium combination to open up
     the portal to the next level.  This is worth 25,000 quest experience.
     The portal you want to enter is the Right Portal (x 2800 y 1400).
   - LEVEL FIVE (AR 3019)
     Well here we are on the final level.  In fact, you can see the Final
     Seal just ahead.  All you have to do is figure a way to open it.  The
     other portal here takes you out of the dungeon.
     There are 3 doors around this area, one below, one to the left and one
     to the right.  Open the lower door (x 2460 y 2460) and talk to the
     Helmite Ghost.  Be confident and tell him that you are ready for anything
     that might be ahead.  Tell him that you are ready for the challenge and
     he tells you to enter the 3 doors behind him.
     Enter the left door first (x 2300 y 2950).
     (AR 3025)
     You will be fighting orcs in here.  Lots and lots of orcs.  This area is
     on a timer.  As long as the timer is going, there will be a constant
     supply of orcs for you to fight.  So, until the end, there will be 10
     orcs in the room.
     After a short while, the spirit appears, congratulates you and gives you
     21,000 quest experience.
     Search the pool for:
       Ixil's Nail (Cespenar can upgrade)
       5 Potions of Extra Healing
       minor treasures...
     Go back up.
     (AR 3019)
     Now open the middle door (x 2640 y 3000) and go down.  You will be
     fighting a Dragon, so be warned.
     (AR 3024)
     This challenge is much more interesting, you get to fight a Green Dragon!
     I found this dragon quite a bit easier than the Red one earlier.  Anyway
     I simply summoned up some Mordenkainen's Swords (2), a Fire Elemental.
     Then I cast a few protection spells and hacked at the dragon till he
     died.
       Dragon - 62,000 experience

                1500 gold
                other treasures...
     With the dragon dead, you get congratulated by the ghost and another
     21,000 quest experience.
     Exit.
     (AR 3019)
     Time for the last door (x 2900 y 2900).
     (AR 3026)
     Here you meet up with a gaming imp.  No way out, you'll just have to
     answer her questions.  Oh, and if you fail, she Imprisons your entire
     party.
     First, here is her riddle:
       "I have as many brothers as sisters, but my brothers have twice the
       number of sisters as brothers. How many children do my parents have?"
       Answer:  Seven
     This is worth 10,000 quest experience.
     Next you play the Game of Coins.  Here is the way to win at this:
       You take:
       2 coins (he'll take 1 coin)
       3 coins (he takes 3 coins)
       1 coin (leaving him the last coin, so he loses!)
     Beating the Imp again is worth another 10,000 experience.  The Spirit
     appears again, congratulates you and gives you another 21,000 quest
     experience.
     There are 3 containers in here with various minor treasures.  Also, the
     chest against the wall is TRAPPED.  When you're done looting, exit.
     (AR 3019)
     When you appear, the Spirit talks to you, and gives you the Heart Key.
     (actually, for me, he gave it to Jaheira)
     1 key down, 2 to go.
     Go up and to the left, and open that door (x 1240 y 1580).  Kill off any
     monsters in here.  This is the Orb Room, where colored balls shoot out of
     a machine to be deposited in large pillars.  Why, you ask?  For a key.
     Go up and examine the machine.  You'll have to go through the Notes
     before it actually lets you play with the machine.  You're going to have
     to press each of the 4 buttons 4 times.  Each time you press a button you
     get a new Orb of the same color as the button.  After you get an orb,
     place it into the same colored Pillar.  There are some side effects to be
     aware of:
       Note:  Despite what the machine says, you only have to put ANY ONE of
              the colored globes into their proper Pillar.  That means you can
              get away with pushing only 4 buttons total, rather than 16.

       Tip:  With the "purple" undead monsters, I turned the script off of my
             Cleric, and had her stand near where the monsters appear.  Then,
             because of being at a high level, every undead was blown to bits.
     Here's a list of what the first 3 orbs do for each color: (Dave Loveland)
       Green - Summon Shambling Mound
       Green - Melf's Acid Arrow
       Green - Temporary +5% magic resistance (on caster)
       Blue - Cone of Cold
       Blue - Greater Restoration
       Blue - Protection from Normal Missiles
       Purple - Invisibility
       Purple - Mass Cure
       Purple - Cloud Giant Strength (on caster)
       Red - Fireball
       Red - Good Luck (temporary +1 to saves for each member of your party)
       Red - Heals 64 hit points
     When you're done, you get the Mind Key, which is worth 10,000 quest
     experience.  2 down, 1 to go.
     Go over to the right door (x 2900 y 1300) and go in.  You'll have to
     fight through some enemies, but nothing you can't handle.  Go up to the
     pedestal and click it to place the Skull you got from the dragon on it.
     This teleports you to a hidden realm ...
     (AR 3023)
     You cannot move.  In fact, all you can do is control the Spirit Warrior
     and tell him where to go.  This dungeon has been reduced to almost a
     Text Adventure level.  Your Spirit Warrior has 50 HP, 7 AC, 10 THAC0.

         Wand Note:  If you don't use your wand beforehand, it will be more
                     powerful when you fight the Mummy later.
         Fleeing Note:  If you flee the goblin you take 2 damage.
                        If you flee the skeleton or War Dog you take 5 damage.
                        If you flee the ghost you take 7 damage.
         Experiences:  You get 4000 quest experience for getting the Helm.
                       4000 QExp for getting the Potion & Key.
                       4000 QExp for getting the Scroll
                       4000 QExp for getting the Bracers
                       3000 QExp for using the Scroll on the Gibberling
                       4000 QExp for using the key and opening the chest
     As you can see from the map, there are many ways to do this one.  The
     route I favor is this:
       Room 1:  Go North to 4.
       Room 4:  Go North to 7.
       Room 7:  Kill ghost, open chest to get the +1 AC Helm.  Go south.
       Room 4:  Go south to 1.
       Room 1:  Go east to 2.
       Room 2:  Fight goblin.  East to 3.
       Room 3:  Open chest, fight skeleton, get Wand.  Go up to 6.
       Room 6:  Fight War Dog, search for Potion (Heal) & Key.  West to 5.
       Room 5:  Search for Scroll.  Up to 8.
       Room 8:  East to 9.
       Room 9:  There is a 33% chance to get poisoned if you open the desk.
                The Bracers +1 THAC0 are nice, however.  North to 10.
       Room 10: Use Scroll to kill Gibberling.  West to 11.
       Room 11: Open Chest (needs the Key from room 6) to get healed.  Go
                through the Arch to 12.
       Room 12: Fight the mummy.  Use the Wand first, then attack.
     If you don't want any of the items, the non-violent (at least until you
     get to the Mummy) route is:
       Room 1:  Go north to 4.
       Room 4:  Go east to 5.
       Room 5:  Search for scroll.  North to 8.
       Room 8:  East to 9.
       Room 9:  North to 10.
       Room 10: Use Scroll to kill Gibberling.  West to 11.
       Room 11: Go through Archway to 12.
       Room 12: Fight Mummy.  I believe the mummy is stronger if you don't
                have the Helm and Bracers.
     Thus you are released from the Spirit Warrior, having succeeded in
     getting the final key.  For this you get 21,000 quest experience.
     (AR 3019)
     Go over to the great Seal on the floor.  There are 3 pedestals around it,
     click on each of these.  Each key used gets you 20,000 quest experience
     (for 60,000 total).  Now that we've stuck the keys in, we still have
     to turn them.  And when you turn the keys, monsters appear.  As soon as
     you turn the key, I'd pause it and survey your enemies.  If you have any
     mages, take them out quickly to avoid getting Time Stopped.
       Upper Right - Spirits of Priests (and one mage)
                     Items:  Club of Detonation +3
       Lower       - Lich (25,000 experience), Flaming Skulls
                     Items:  Erinne Sling +4 (upgradeable by Cespenar)
                             Serpent Shaft (upgradeable by Cespenar)
       Upper Left  - Final Guardians
     The Final Guardians are meant to be very tough, and so they are.  They
     consist of:
       Nalmissra - Tanar'ri
                   25,000 experience
                   Scroll:  Wish
       The Huntress - Demonic
                   20,000 experience
                   Taralash Bow +4 (increases movement rate, Upgradeable)
       Y'tossi - Demonic
                   23,000 experience
                   Gauntlets of Extraordinary Specialization (+1 THAC0, +2 dmg
                     + 1/2 attack per round)
       Amerilis Zauviir - Cleric
                   20,000 experience
       Hive Mother - Beholder
                   50,000 experience
       Xei Win Toh - Fighter
                   28,000 experience
                   There are also lots of minor treasures too.
     To prepare for the final battle, I summoned up some Mordenkainen's Swords
     and placed them around the portal.  I then moved my party well over to
     the left, cast protective magics on them (and a Simulacrum as well).
     If you have the Cloak of Reflection or the Shield of Balduran, be sure
     to have those equipped on someone, and have them rush the Beholder.
     I had the Swords attack Y'tossi as she is very tough and requires high
     enchantments (the Swords are +5) to even hit.  I then hit Nalmissra
     (after doing a Remove Magic on her) since she was close before
     concentrating more fully on the Beholder.  Once those monsters are gone
     it's practically smooth sailing.
       Note:  Getting killed by Instant-Death attacks?  Try using the Death
              Ward (cleric) before hand.
              Saving after the battle is a GOOD idea.
     Alan Cherry has a good idea:  Keep everyone near the exit portal.  Take
     out one or two of the opponents, then use the portal and leave as soon as
     someone's hurt bad. Heal up and recharge spells, and come back in. As
     long as nobody's too far from the portal, you can exit anytime. Cast
     Resist Fear before entering, since you can't control a character who
     panics.
     Konstantin has a more magical strategy:  All it requires is a Mage or a
     Sorcerer and the skull trap spell.  I call this the chain reaction.
     Anyway, the best kind of fight is when you get the XP for free.  So I had
     my thief set snares around the room and then using project image I had my
     Sorcerer pump the room full of skull traps about 12 in each of the places
     where the monsters would appear.  This of course took a few minutes.
     Then I took a rest and cast all of my protective spells, and got ready
     for a fight.  I carefully came up to the key thing (whatever it is) and
     turned the key.  There was a laugh, then my screen froze for a few
     seconds as the skull traps were going off, when everything was finished
     all the guardians were dead.  They did not touch me once.
     Xander77 offers the following strategies:
       To begin with. it may be a good idea to kill all the monsters at the 

monster machine except for the purple (undead) ones. Then start turning undead with a sanctuaried cleric and recruit a bunch of Vampires,

       Skeleton Warriors and Liches to your cause before going after the 

guardians.

       Finish the other seal guardians, rest-up and buff-up (For this battle I 

suggest summoning 1 planetar 2-3 skeleton warriors/hashekars and 1-2 Mordenkainen's Swords. Cast a storm of venegance over the area if you

       feel like it. Now. arrange everyone according to the strategy of your 

choice and - open the last seal.

       Strategy 1 - General pile-up.
       Simple enough - send all the summoned creatures into battle. Let your

characters stand back and use every area-damage spell they know (preferably summon-friendly ones). Chain-contingency + horrid wiltings might work here (it might work in any big combat). Timestop + Improved Alacricity is also nice.

       Strictly according to the rules. A bit-touch-and-go, but doable

(especially if your level is 20+)

       OTOH - It does seem somewhat impersonal, doesn't it? Going on to:
       Strategy 2 - divide and conquer.
       Make sure that all your guys and summons take their assigned places 

(see below) except for one mage that opens the final seal. At this point we handle 3 of the guardians on a party-monster basis, while the summons distract the other 3. Simple enough.

       Nimarha - Send a guy with negative plain protection (IMOD for example) 

and charm protection against her. All her attacks are ignored, while the guy uses a ranged weapon to help his friends. If you can find a

       mage with the above specifications - even better. We need all the 

fighters we can get taking down Ytossi and the Hive mother - the mage can just stoneskin, and sit there doing his thing.

       Ytossi - a fighter or 2. Breach her protection from magic weapons (a 

mage should alternate between breaching her, breaching the hive mother and magic missiling anyone who seems to be up to something).

       Hive mother - one guy with Cloak of reflection. An enraged Korgan is 

good - maze and imprisonment won't work. Possibly another guy with high MR\Cloak of Balduran to help him send her on her way before she starts targeting the other party members.

       BTW - If your main char is a fighter, you can distract them all the 3 

on the right by yourself, and let the summons help your party. Both the kensai and the archer have +1 weapons (the archer has a +2/ or maybe +3 sword, but she only uses it once she runs out of arrows) so they can't hurt you. You should carve the drow up bad enough that she won't have time to fire of a spell.

       Vice versa - you can handle the 3 on the right with your party (just 

run on in and keep hitting them. Keep a mage free to keep the 3 on the left in line) and let the summons handle the ones on the left in the

       meantime. In which case:
       Namirra - One skeleton warrior, or something else she can't charm and 

can stay alive after a level drain or 2.

       Ytossi - one mordy sword. 2 if you feel like breaching and letting them 

finish her.

       Hive mother - one skeleton warrior and one Hakeashar.  Both magic 

resistant.

       Planetar - wanders around and kills anything that needs killing.
       Cast a death word on your weaker party members in case a spell goes 

after the wrong person, and finish the whole thing quickly - they start turning to opponents other then the ones they're currently facing after a while.

     Once they're dead and gone, time to click the Wheel above the Seal to
     open it.
     Going down...
   - THE IMPRISONED ONE (AR 3020)
     Ah, finally we meet the elusive "Imprisoned One"...  He'll try to talk
     you out of using the Scroll you were given, at the moment we don't want
     to listen to that.  Get out of the conversation, put the scroll in a
     Quick Item Slot and use it.  This is worth 80,000 quest experience.
     Of course, the Imprisoned One was right, and you are now trapped down
     here.  You can go up the stairs and look at the portals, but you sure
     can't do anything about it.  Talk to the demogorgon again.  Listen to its
     plan, it will open a small rift in the seal to let you out, you go talk
     to the false-Helmites and trick them into coming to check on the
     Imprisoned One, he kills them and everyone is happy.  Sounds like fun.
     Agree, and he'll open the portals.
     Use the Right Portal to get back to the beginning.
     (AR 3000)
     You'll appear on the ground level, find the stairs up to the roof to
     talk to Odren.  Tell him what the Imprisoned One told you to tell him,
     (that you killed the Imprisoned One) and they'll go rushing down to
     check for themselves.
     After that a Specter appears and talks to you.  She tells you that Odren
     was indeed corrupt, that it was He who was supposed to do the ritual
     binding the Demogorgon (prince of demons) in the Keep.  He wimped out
     and thought to sacrifice you.  She says Helm has sealed his fate.  She
     gives you three options to do:
       Flee in Terror
       Enter the Keep and Save Orden
       Use a New Scroll to Seal both Demogorgon and Orden inside
     Pick either Enter the Keep or Use the Scroll and she'll give you the
     scroll (just in case).  This is worth 25,000 experience.
     The easiest is to simply take the New Scroll, use it and seal both
     inside.  This gets you 80,000 quest experience.
       Note:  Once you seal the Demogorgon in with the Scroll, you can never
              again attempt to kill him.
              ... Except for a very small area on the door that still allows
              you to enter, that is.
     Of course, many people might think it too easy to simply use a scroll,
     if so the it is time to go back inside.  Drop down the stairs to the
     ground, then over to the left and into the Demogorgon's Lair.
     If not, then congratulations on completing the Watcher's Keep.
     (AR 3020)
     Everyone dies really quickly around the Demogorgon, so you can't expect
     help from the "knights."  Demogorgon also summons up a pair of Mariliths
     (similar to Y'tossi from earlier) making this a very tough battle indeed.
     Anyway, before dropping down to his level, you'll want to prepare
     yourself.  Protection spells, summonings, anything you think might help.
     Make sure everyone has +4 weapons so that they can actually hit something
     down there (otherwise, just leave them up by the portals).  If you kill
     one set of minions, he'll summon more.  In order to hit the Demogorgon
     you'll need to lower his defenses.  I would suggest Khelben's Warding
     Whip.  Use all of your special abilities/items/spells that you can while
     in the battle.  There's no better time than now to try out your Whirlwind
     attacks.  It is not ESSENTIAL to take out his Mariliths, you could leave
     them be and just try to kill Demogorgon.  If you do kill his Mariliths
     he'll summon more... again and again.  Remember, you can't hurt him
     if he has protections on, so use Warding Whip!
     If you have the higher abilities, summon Planetars and other similar
     creatures (those can sure take a beating).  You may get poisoned, so
     either have an antidote, or a spell handy.  Set up Contingencies if you
     can, and Spell Triggers.
       Demogorgon - 290 HP  -12 AC  -8 THAC0  5 Attacks
                    36,000 experience
       Mariliths  - 23,000 experience
       Balor      - 26,000 experience
       Glabrezu   - 12,000 experience
       Cambion    - 18,000 experience
       Note:  This is probably the most difficult battle in any of these
              games, so if you can't do it after several attempts, try
              coming back later.
              Also, you cannot cheat to kill the Demogorgon.  It won't work.
              Demogorgon is not stopped by Time Stop, so unless your mage
              can fight him on his/her own, don't use it.
              Exploits work against Demogorgon quite well.  Drop a "Pit
              Trap" in the center before he appears (Or, drop several). Or
              if you're into magic, use the Project Image spell exploit to 
              summon multiple Planetars.
              Find Demogorgon too easy?  Try David Gaider's (a senior designer
              at Bioware) more difficult Demogorgon:
                http://www.baldurdash.org/ToB/TOBtweaksandcheats.html
     Killing the Demogorgon is also worth 100,000 quest experience.  Talk to
     Orden to get 20,000 quest experience.
     Either way, you are done with the Watcher's Keep!
