The cave winds its way several hundred feet before coming to an abrupt stop. The only egress is a hole in the ceiling leading up to the chamber above.
The hole looks to be about 10 feet long, and rests 5 feet above the water's surface.\
Flying up it is of course easy, but climbing it would be difficult DC 25 by the looks of things.

Daliya |

"Shall we use some charges from the plundered wand?" Daliya suggested. A faster, quieter approach seemed like a good plan, and it wasn't using resources they'd been counting on.

Krom Manirah |

"Or Gurram could carry everyone up," Krom offers. Gurram seems indifferent to the idea.

Ixrul Morcrom |

"Going in flying seems wise regardless. At least for those of us who don't wish to be in hand-to-hand."

TheGuyKnownAsAce |

"Would it not be wiser to send an inconspicuous scout up there first, captain? like those flying eyeballs or whatits you possess?"

Ixrul Morcrom |

"I can send the eyes ahead, but their range is limited. We should all fly, though."
Ixrul uses the wand to grant everyone flying, then we proceed with the eyes going in advance. He also casts his Extended Magic Circle Against Evil on himself.

Ixrul Morcrom |

"There's something large there. Instantly killed them both silently."

Daliya |

"Impressive," Daliya noted. "Any precautions we can take before we head up?" Perhaps a first wave of summoned creatures that could fly and were tough might keep it busy for a while so they could join the fight a moment later.

Ixrul Morcrom |

"Aye."
Ixrul begins casting Summon Monster 6.

Ixrul Morcrom |

Ixrul summons a Shadow Demon (+4 Con) to scout ahead. Assuming I'm not misunderstanding a the description of the place and we are actually very close to sunlight.
He will have it use its incorporeality to get a view of the creature safely so it can report back via its Telepathy.

Storm Dragon |

There is light above, but it's fairly dim.
The shadow demon ascends, and returns to report after a short time.
<The area above is a giant sinkhole, in which an enormous scorpion lurks.> it whispers in your mind.
<Beyond is a complex of 10 further rooms. Many of the rooms are occupied with armed men, but some mutilated prisoners and worshipers as well. A shrine to some god is the centerpiece; whose I do not recognize."

Ixrul Morcrom |

Can I respond telepathically if it's still in range? Also, how many rounds did it take to scout? I have 17 rounds total.

Ixrul Morcrom |

I have magic tattoo the and conjuration school ability.
Ixrul will have it use its Shadow Evocation to attempt to exhaust the creature with Heatstroke (DC 19 will to reduce to 20%, then DC 19 fortitude), and its Shadow Conjuration to use Acid Arrow and injure the creature as much as possible (DC 18 will to reduce to 20%). Going a level lower because I wanted quieter spells.
It has 3 charges on each.
Touch attacks:
1d20 + 11 ⇒ (15) + 11 = 26
1d20 + 11 ⇒ (10) + 11 = 21
1d20 + 11 ⇒ (15) + 11 = 26
1d20 + 11 ⇒ (16) + 11 = 27
1d20 + 11 ⇒ (3) + 11 = 14
1d20 + 11 ⇒ (20) + 11 = 31
Last acid arrow threatens.
1d20 + 11 ⇒ (20) + 11 = 31

Storm Dragon |

Will vs Heatstroke: 1d20 ⇒ 10
Fort vs Heatstroke: 1d20 ⇒ 8
Will vs Heatstroke: 1d20 ⇒ 9
Fort vs Heatstroke: 1d20 ⇒ 14
Will vs Heatstroke: 1d20 ⇒ 13
Fort vs Heatstroke: 1d20 ⇒ 8
Will vs Acid Arrow: 1d20 ⇒ 13
Damage: 2d4 ⇒ (3, 3) = 6
Nonlethal: 3d4 ⇒ (1, 1, 2) = 4
Everything goes fairly well for you until the acid comes into play.
The creature, feeling already uncomfortably warm, and now covered with a burning acid, leaps down the hole into the water. Once there, you can see the shadow demon's description of it as a scorpion is...not quite accurate.
From its fin-like (yet still barbed) tail, you can deduce that it appears to be some kind of amphibious creature that is very much like a scorpion.
Party Initiative: 5d20 ⇒ (18, 8, 14, 2, 3) = 45
Mr. Clack Initiative: 1d20 ⇒ 17
Ixrul (26)
Ace (24)
Mr. Clack (23)
Gremory (14)
Daliya (10)
Krom/Gurram (8)
Also I blew the dust off the map; it hasn't been needed since Sumitha.
If anyone has pics they want me to use, put them in your handout I'll turn them into tokens.

Ixrul Morcrom |

First things first...
Kn Nature: 1d20 + 16 ⇒ (7) + 16 = 23
Also, what size is it? Map says 15ft squares which would make it 45 ft...

Storm Dragon |

I missed that bit. It's size huge.
This is a mutated Spiny Eurypterid, much larger than normal and apparently amphibious. They are a prehistoric "sea scorpion" with a deadly poison carried by the stinger, and covered in spikes that painfully hinder attempts to attack it unarmed or with natural attacks. It is an especially bad idea to grapple one.
They are large, mindless, and intensely aggressive vermin, and attempts to hide in the water or on the ground are fruitless, as they have Tremorsense.

Ixrul Morcrom |

"Be careful, it's stinger is very poisonous. Also, try not to attack it bare-handed."
Given 10 rounds were expended exploring and 4 were expended casting spells, I have ~3 rounds left on my Shadow Demon.
Given that he would probably die in one or two hits, Ixrul Withdraws from the creature.
<Kill it.>
The shadow demon pounces in, using its Sprint as necessary.
Claw vs Touch: 1d20 + 11 ⇒ (19) + 11 = 30
Phys/Cold: 1d6 + 1d6 ⇒ (4) + (3) = 7
Claw vs Touch: 1d20 + 11 ⇒ (9) + 11 = 20
Phys/Cold: 1d6 + 1d6 ⇒ (1) + (2) = 3
Bite vs Touch: 1d20 + 11 ⇒ (8) + 11 = 19
Phys/Cold: 1d8 + 1d6 ⇒ (6) + (6) = 12
Also - does it seem exhausted? Heatstroke fatigues (or exhausts fatigued creatures) on passed saves. Though IDK if it just will-saved through some of those, even though this think presumably has pretty bad will saves.

TheGuyKnownAsAce |

"I aint even going near that thing even with a weapon"
Ace snaps off a shockwave at the beast
Wave of mutilation, I think I got the numbers right
atk: 1d20 + 15 ⇒ (19) + 15 = 34
damage: 1d6 + 12 ⇒ (2) + 12 = 14
DC20 reflex save for half damage

Daliya |

Since attacking the thing with physical attacks would end...poorly, Daliya used the Fly magic to keep her distance and cast instead. She instead tried to Entangle the thing.
Reflex save to avoid being entangled, then a Fortitude to avoid being sickened. Both are DC 17.

Krom Manirah |

Gurram lets out a frustrated grunt.
"Hey, don't worry, Gu!" Krom reassures her. "We'll find something here that you can eviscerate with your claws, I'm sure of it!
For now, the pair repeats the strategy they used on the anemone: Fly in, hit with lance, and fly out before it can retaliate.
Spirited Wheeling Ride-By Charging Power-Attack Bull's-Strength Lance: 1d20 + 17 ⇒ (9) + 17 = 26
Damage: 3d8 + 60 ⇒ (2, 7, 2) + 60 = 71

Ixrul Morcrom |

<Try to Magic Jar it. If you succeed, flip it to its most vulnerable angle relative to my compatriots.>
DC 19 Will. If it has a spikeless underbelly, Ixrul wants it exposed.
1 round on the shadow demon left.
Ixrul will wait to see if the creature gets jarred before deciding what to do.

TheGuyKnownAsAce |

Ace growls as the poision works its way through his system, and lets loose a flurry of magic missiles.
5d4 + 5 ⇒ (2, 4, 2, 2, 2) + 5 = 17

Ixrul Morcrom |

How - it's literally a bug!
Shrugging off it's shockingly iron will, Ixrul begins casting Summon Monster 5.

Storm Dragon |

53 damage dealt to Mr. Clack.
As nobody else is close enough to viably attack the eurypterid, it focuses on Ace once more.
5 ft. step, as I assume Ace 5 ft. stepped away to avoid an AoO from Magic Missiles.
Claw 1: 1d20 + 20 ⇒ (11) + 20 = 31
Damage: 2d6 + 10 ⇒ (5, 1) + 10 = 16
Claw 2: 1d20 + 20 ⇒ (7) + 20 = 27
Sting: 1d20 + 20 ⇒ (20) + 20 = 40
Damage: 1d6 + 10 ⇒ (2) + 10 = 12
Confirm?: 1d20 + 20 ⇒ (9) + 20 = 29
Damage: 1d6 + 10 ⇒ (6) + 10 = 16
Ace take 44 damage and make another Fort save vs poison, this time DC 27 or take 1d4 ⇒ 4 Con and 1d2 ⇒ 2 Dex damage. Make sure to factor in that every -2 Con deals 11 damage to you as well. If you fail, that's 33 total damage just from poison between this and last round.
Ixrul (26)
Ace (24)
Mr. Clack (23)
Gremory (14)
Daliya (10)
Krom/Gurram (8)
Gremory, Daliya, Krom/Gurram are up! Then Ixrul and Ace at the top of the next round.

Daliya |

Well, this thing was vicious. Daliya called up a Snowball, hoping to at least aggravate it.
To Hit (Touch): 1d20 + 10 ⇒ (18) + 10 = 28
Damage (Cold): 5d6 ⇒ (1, 5, 6, 4, 1) = 17

TheGuyKnownAsAce |

Ace will do exactly that when his turn comes. (after moving a fair distance away first)
"thanks mr skeltal"
I will be very busy with work the next few weeks, so sorry if I miss anything

Gremory Ainsworth |

If Gremory has/needs the space to move last turn, she'll full attack with this turn.
Att 1: 1d20 + 15 ⇒ (1) + 15 = 16 Only factoring in Heroism
dam: 1d12 + 14 ⇒ (7) + 14 = 21
Att 2: 1d20 + 15 ⇒ (16) + 15 = 31
dam: 1d12 + 14 ⇒ (8) + 14 = 22
Att 3: 1d20 + 15 ⇒ (20) + 15 = 35
dam: 1d12 + 14 ⇒ (12) + 14 = 26
Well, there's that.

Krom Manirah |

"Quit picking on Ace, you acrimonious arachnid!"
Krom and Gurram do the same thing as last time.
S.W.R.B.C.P.A.B.S.L.: 1d20 + 17 ⇒ (1) + 17 = 18
Damage: 3d8 + 60 ⇒ (4, 7, 6) + 60 = 77
Hey, who snuck Grem's unlucky d20 into my hand?

Storm Dragon |

The Eurypterid closes in on...Ixrul I think is the closest guy now that Ace has moved away.
STINGA: 1d20 + 20 ⇒ (14) + 20 = 34
Damage: 1d6 + 10 ⇒ (2) + 10 = 12
Ixrul: 12 damage, a Concentration check, and a Fort save for me please.
Everyone is up! Going to try to expedite this combat a bit now. I'm going to assume unless otherwise stated that Gremory's action is to unjam her gun, so if everybody else posts before that we're moving on.
