My group also found Mahir's cache... with the help of a Drow rouge supplied by the Snake-lady.
They found the book and I also used this as a chance to give the characters some magic items as they are a bit low. They found a +2 Bastard sword, a +4 Cha cloak, a +1 icy burst sickle, an amulet lf +2 Natural Armor and an Ion Stone that gives +1 AC.
They gave the Book to Snakey. After a few days she found the Ritual of Unmaking and gave it to the characters and kept the rest of the book. I think I'm going to turn her into one of the Spider Kings and she'll set herself up down in I.
The group had given up on the Ritual as they heard what was needed in order to use it (those high Spellcraft rolls). They finally had the idea to ask Keldara if any of the Garrison Members could do it... She has a +17 Spellcraft skill as does her 2nd in command. After some thought she said she would be willing to do it but refused to risk both her and her 2nd.
The basic plan was to cast the Ritual onto Madness and then fight Anguish when he showed up. As the group had not met Anguish yet they went off to see what he was all about.
Knowing he was to the W they went straight to his lair. He swooped down, did his lighting bolt and landed to fight.
3 rounds later he was 'dead' with minimal damage to the party.
Thinking that was easy and having never really stopped to fight Madness they headed over to 'finish this'.
I've been giving Madness a 50%-50% chance to be lying in wait for the party since he knows they are around. He was... so he was waiting in a hallway trying to be quiet. The party heard him gibbering anyway... (gobble-gibber-shhhhhh-blork-splirt-sshhhhhhh) and backed off. He came out and moved to engage the party.
First round he does 50 some damage to the high AC fighter taking none in return. The party realizes that Madness is NOT Anguish.
Round 2 the halfling cleric of war moves up to join the fun. As he did NOT have a Freedom of Movment cast on him (as the main fighter did) he took 40 some points of damage and was grappled by the little mouths.
The main fighter tries to sunder one of the mouths. He does 18 points with his axe... - the 15 points for it not being a Blunt weapon he JUST manages to cut it off as it streaches all the way to the floor before breaking.
One of the other characters hits it with Sendar's Holy Spear. Not only does it NOT flash for extra damage (Madness is N) most the damage closes back up.
The little hafling gets away as another Freedom of Movement is cast on him by another Cleric. He moves away but this leaves her next to Madness.
57 points of damge and 3 mouths attached to her... the Cleric of War casts a FOM on her (dang that spell!) and everyone runs away.
Net result: about 150 points of damage dealt out by Madness and he took 5 in return.
The party DID get a chuck of Madness to use for the spell though.
Next game they try to Ritual. I think I'll take a page out of BBR's book and let them cast it twice. Either that or Angish learns to leave them alone.
Though... I'd like to make Anguish a bit tougher as he was a total push over for the group. Maybe with the idea that each time they 'die' and come back they are tougher (and Madness has had this happen to him more which is why he's tougher).
Any idea other then just adding some HD to him?
