Valgrim Twin-Axe |

The three creatures are separated so you're still going to catch only one of them, Vug, if you see the map. Let's just say you threw it at the closest one.

Friar Feres |

Round One:
Feres offers a quick prayer to his Goddess, calling upon Her divine power to sheathe himself in a shimmering field of magical force. Hefting his scimitar and shield, the stout priest moves to engage one of the tentacled monstrosities.
Standard action to cast Shield of Faith on self, granting +3 deflection bonus to AC. Move action 20 ft to square S,12 - hopefully the creature doesn't have Combat Reflexes and can't make an AoO while flat-footed.
Feres' AC: 22
Feres' HP: 66/66
Party Buffs/Spells in Effect:
Darkvision: extract from Vug taken prior to entering the sewers; original duration 2 hours.
Daylight: cast at beginning of battle with drow spellcasters; original duration 80 minutes.
Resist Energy (Fire) - Valgrim only: cast before scouting past shrieker/yellow mold cavern; original duration 60 minutes.
Freedom of Movement - Valgrim only: cast following battle with drow spellcasters; original duration 80 minutes.
Haste: make extra attack at full BAB during full attack action, +1 bonus to attack, +1 dodge bonus to AC and Reflex, +30 ft enhancement bonus to all modes of movement; duration 8 rounds.
Inspire Courage: +2 competence bonus to attack and damage, +2 morale bonus to saves vs. charm and fear effects; duration current round plus 2 rounds after ceasing performance.
Shield of Faith - Feres only: +3 deflection bonus to AC; duration 8 minutes.

Vug Vang |

The three creatures are separated so you're still going to catch only one of them, Vug, if you see the map. Let's just say you threw it at the closest one.
Yeah, I can't see the map at work. Just pick one of them, it doesn't matter which.

Black Tom |

Sorry, got a bit swamped and couldn't get around to updating.
Vug lobs a flask that shatters on the wall behind the creature to the left and releases noxious vapors that render the creature temporarily helpless. Valgrim and Feres move to engage the remaining two, and Valgrim deals a severe blow to his foe. Bubba uses his magic to speed you up.
Feres will need to save against its slowing gaze but it will only negate the Haste if failed.
The monsters retaliate, failing to get a grip on the stout priest, but making a serious effort to tear Valgrim to pieces, grasping him with its claws and tearing for 30 points of damage.
You are all up.

Valgrim Twin-Axe |

Ouch!
Valgrim bears the pain through gritted teeth and goes full-attack on the wounded creature!
Hasted Attack: 1d20 + 13 + 1 ⇒ (16) + 13 + 1 = 30
Damage: 1d12 + 16 + 1d6 ⇒ (12) + 16 + (4) = 32
Attack: 1d20 + 13 + 1 ⇒ (9) + 13 + 1 = 23
Damage: 1d12 + 16 + 1d6 ⇒ (6) + 16 + (3) = 25
Attack: 1d20 + 5 + 1 ⇒ (17) + 5 + 1 = 23
Damage: 1d12 + 16 + 1d6 ⇒ (8) + 16 + (6) = 30
AC: 23
HP: 53/83

Friar Feres |

Will save: 1d20 + 14 ⇒ (19) + 14 = 33 - I'm going to go ahead and assume that succeeds.
Round Two:
Feres tries to emulate Valgrim and slashes repeatedly at his tentacled foe.
Full attack action with scimitar.
Attack #1: 1d20 + 9 + 2 + 1 ⇒ (18) + 9 + 2 + 1 = 30
Damage: 1d6 + 3 + 2 ⇒ (4) + 3 + 2 = 9
Crit Confirmation: 1d20 + 9 + 2 + 1 ⇒ (16) + 9 + 2 + 1 = 28
Additional Crit Damage: 1d6 + 3 + 2 ⇒ (6) + 3 + 2 = 11
Attack #2: 1d20 + 4 + 2 + 1 ⇒ (13) + 4 + 2 + 1 = 20
Damage: 1d6 + 3 + 2 ⇒ (1) + 3 + 2 = 6
Hasted Attack: 1d20 + 9 + 2 + 1 ⇒ (5) + 9 + 2 + 1 = 17
Damage: 1d6 + 3 + 2 ⇒ (2) + 3 + 2 = 7
Feres' AC: 22
Feres' HP: 66/66

Vug Vang |

Vug tries throwing a stink bomb near the remaining tentacle monster without looking at it.
Targeting grid intersection again: 1d20 + 12 + 2 + 1 ⇒ (13) + 12 + 2 + 1 = 28, 9 splash damage, nausea, DC 19
By the way, Feres's list of buffs is missing Resist Energy (electric); we drank it in the mold room and it lasts for 15 minutes. I'm not sure if it has worn off by now or not.

Vulcan Stormwrath |

Vulcan focuses his baleful stormy glare on the horrific creature that is as yet unengaged, heeding Bubba's advice and unleashing twin bolts of scorching heat at the aberrant monster.
Ranged touch1d20 + 5 ⇒ (20) + 5 = 25
4d6 ⇒ (5, 2, 2, 2) = 11
Ranged touch1d20 + 5 ⇒ (8) + 5 = 13
4d6 ⇒ (5, 4, 4, 2) = 15
crit
Ranged touch1d20 + 5 ⇒ (18) + 5 = 23
4d6 ⇒ (3, 6, 2, 6) = 17
Will save 1d20 + 6 ⇒ (20) + 6 = 26

Valgrim Twin-Axe |

Valgrim 5' steps and full-attacks the creature:
Hasted attack: 1d20 + 13 + 1 + 2 ⇒ (3) + 13 + 1 + 2 = 19
Damage: 1d12 + 16 + 2 + 1d6 ⇒ (5) + 16 + 2 + (5) = 28
Attack: 1d20 + 13 + 1 + 2 ⇒ (2) + 13 + 1 + 2 = 18
Damage: 1d12 + 16 + 2 + 1d6 ⇒ (11) + 16 + 2 + (3) = 32
Attack: 1d20 + 5 + 1 + 2 ⇒ (14) + 5 + 1 + 2 = 22
Damage: 1d12 + 16 + 2 + 1d6 ⇒ (2) + 16 + 2 + (6) = 26
AC: 23
HP: 53/83

Valgrim Twin-Axe |

Valgrim drinks 2 Cure Light and 1 Cure Moderate Wounds potions.
2d8 + 2 ⇒ (5, 3) + 2 = 10
2d8 + 3 ⇒ (5, 3) + 3 = 11
HP: 74/83
He then goes back to trying to open the marble doors (take 20 if possible). By the way, Resist Energy lasts 10 min/level so there is no way it would have lasted 15 minutes.

Black Tom |

After a fair amount of bashing Valgrim manages to smash the doors to the point that you can lift the bar off and enter the room behind.
As you pass through the doors the natural cavern yields to worked stone with a tentacle pattern. The ceilings are 40 feet high. You enter a round room, 30 feet across, with an exit to your left.
In the center of this tall domed chamber is a large brain, carved from a single block of purple-veined white marble. Its veins seem to pulsate with every breath you take, as if aware of your presence. Four stone benches are arrayed around the room, each with a pair of iron manacles bolted to the top.

Valgrim Twin-Axe |

"Vug, room looks suspicious to me, what with the stone brain and all. Can we send in one of those decoys to spring a trap that you mentioned earlier to see what happens?"

Friar Feres |

Before Valgrim opens the door, Feres gives the dwarf and himself a tap from his lesser curative wand.
CLW Wand - Valgrim: 1d8 + 1 ⇒ (5) + 1 = 6 hp healed.
CLW Wand - Feres: 1d8 + 1 ⇒ (7) + 1 = 8 hp healed.
If we're still under the effects of Bubba's Haste spell, maybe we should just run through the chamber as fast as we can?
Party Buffs/Spells in Effect:
Darkvision: extract from Vug taken prior to entering the sewers; original duration 2 hours.
Daylight - on Feres' shield: cast at beginning of battle with drow spellcasters; original duration 80 minutes.

Vug Vang |

"Sure, it'll just take a minute."
Vug mixes a pinch of this and a dash of that in a vial, shakes it vigourously, then removes the cork with a pop. A tiny homunculus slithers free and grows quickly into a 3-foot-tall ugly blue humanoid -- a mite. (summon nature's ally I)
Vug addresses the mite in Undercommon:
As far as buffs go, Vug also has See Invisibility running (duration 80 mins).

Black Tom |

The mite salutes Vug, giggles a little at nothing in particular and sets off into the room. As it nears the stone brain it suddenly freezes into place and then slowly turns toward you with a malicious grin on its face. With a shrill yell it runs at you, teeth bared.
Knowledge (arcana) 25 or Sense Motive 15:

Valgrim Twin-Axe |

Valgrim steps 5' back from the door. "Thanks, Friar, for noticing that. Got any preventive magic that could help us?"
How close did the mite get to the brain? Anything unusual about the brain? Perception: 1d20 + 17 ⇒ (6) + 17 = 23...add +2 if stone

Valgrim Twin-Axe |

"It's pretty big, Vug. Don't think one bomb will do much to it. I could try to break it, if Friar protected me from its domination magic."

Friar Feres |

Feres offers a prayer to his Goddes to shield Valgrim's mind from malevolent forces. "I have a spell that could enhance your strength as well," Feres offers the dwarf. Cast Protection from Evil on Valgrim; duration 8 minutes. If Valgrim desires, Feres will cast Bull's Strength on him as well.
Party Buffs/Spells in Effect:
Darkvision: extract from Vug taken prior to entering the sewers; original duration 2 hours.

After casting his spell(s), Feres will use both of his Pearls of Power to recall 2 castings of Protection from Evil.

Valgrim Twin-Axe |

"Thank you, Padre." Buffed by both of Friar's spells, Valgrim approaches the stone brain hopeful that the spells protect him and starts hacking at it with his bardiche with power attack. If he notices the sharp blade is not penetrating, he starts bashing it with his morningstar instead.
Round 1:
Damage with bardiche: 2d10 + 18 ⇒ (5, 6) + 18 = 29
Round 2:
Damage with bardiche: 1d10 + 18 ⇒ (4) + 18 = 22
Damage with bardiche: 1d10 + 18 ⇒ (2) + 18 = 20
Round 3:
Damage with bardiche: 1d10 + 18 ⇒ (2) + 18 = 20
Damage with bardiche: 1d10 + 18 ⇒ (3) + 18 = 21
Round 4:
Damage with bardiche: 1d10 + 18 ⇒ (6) + 18 = 24
Damage with bardiche: 1d10 + 18 ⇒ (3) + 18 = 21
Round 5:
Damage with bardiche: 1d10 + 18 ⇒ (2) + 18 = 20
Damage with bardiche: 1d10 + 18 ⇒ (4) + 18 = 22
I am assuming the brain is not moving and I do not have to roll to hit. If you wish for me to post damage with the morningstar, let me know.

Black Tom |

Valgrim bashes the brain into pieces, protected by Feres's magic.
And you get another 640 xp for that.
Looking down the passage to the left, at the end of a long staircase, an odd chamber reveals itself. A number of tall bookcases, a desk, and a large tank full of green liquid takes up half the room. A stone door stands closed on the opposite wall.
Apart from the door, the passage continues at the other side of the room.

Valgrim Twin-Axe |

"Thank you, Padre, for the spells and Vug for the use of the mite. Great teamwork." Up the stairs we go, Valgrim in the lead, frost greataxe in hand. Perception: 1d20 + 17 ⇒ (9) + 17 = 26...add +2 for stone.

Valgrim Twin-Axe |

Bubba, Valgrim is heading to the room with the bookcases and the tank with the green liquid. Since BT said it was at the end of the staircase, I posted up the staircase. Sorry if I was not clear.

Friar Feres |

Initiative: 1d20 ⇒ 4

Black Tom |

Valgrim and Vug (and possibly Vulcan) react quickly and may act before the monster.
I don't really think that we'll need a map, but the monster is large and has 15 feet reach, in case you are wondering. That basically means that it can reach anyone in the room, but the passage is 10 feet wide, so that won't be much of a problem.
Go break a tentacle.

Valgrim Twin-Axe |

Sorry, BT, but can I insist on a map? Also, confused as to the creature's current position? At the top of the tank about to come out? Outside already? Valgrim had a 26 Perception, in case he was trying to surprise us. I am also a little confused about our respective locations, since Vulcan stated he was by the bookcases and Vug was identifying the liquid (by sight, I assume) and Valgrim was in the lead. It's also important if Valgrim wants to avoid a full attack, given one of the other smaller tentacled monstrosities did 30 damage on Valgrim on a full-attack in 1 round and this is one is even larger!
