No Rest for the Dead in Avlor

INT save: 9

Jarl will also use his reaction to use Halo of Spores on Brix (this would happen on Brix's turn, before the INT save, if that matters), on the off chance that he'll fail a DC 16 CON save and take 6 necrotic damage.

Brix CON save vs Halo of Spores: 28

Oh man, what is going on with these dice?

The cloud of spores surround Brix, but his tough barbarian body resists their effects.

Quote from Esker >>

The rock around the cavern suddenly begins to hum, and you feel something pierce into your minds... (Everyone make an INT save)

Squiggles too? (I'll wait to see result before taking my turn)

Int save: 15

Yeah, I thought about your ring, but it doesn't say that it protects against this. Moot though, since you rolled high enough that nothing happens.

INT save 14

Flynt INT - 15

You all start to feel leeches crawling all over your skin beneath your clothes and armor. For Squiggles, Flynt, and Celric, the sensation lasts only a moment as you recognize the illusion for what it is and it loses its power over you. For Balian, Shale and Jarl, however, the sensation seems completely real to you; you even think you see the leeches crawling on the exposed parts of your skin.

The three of you each take 4 psychic damage. On your turn, if you want to take an action you first need to pass a DC 12 CON check (not save) to summon the fortitude to act despite the sensations. Alternatively, you can use your action to make a DC 14 Investigation check to discover the illusion, ending its effects permanently. (Your ability to take reactions is unaffected)

The aboleth raises its head out of the water and looks straight at Flynt, frustrated that he seems to be unaffected by its illusion. It glares at him with its column of eyes, which seem to glow red for a moment. (Flynt, make a WIS save)

The aboleth then dives down into the water, positioning itself directly underneath Balian and Squiggles at a depth of 10'.

Underwater combat:

Jarl and Celric are up

OoC: My rolls are off the charts atrocious. 

Question: if it's a CON check and not a save, would I have to also do a CON save every turn if I passed the check the first time and cast a concentration spell?

Squiggles:

 Jarl:

CON check: 13

"Oh! That tickles!" Jarl isn't necessarily bothered by the leeches, per se, but they wriggle.

(Damn these rolls!)

Updated map:

Round 3:

Jarl (leechy)
Celric  (20' up)
Brix
Flynt
Squiggles (concentrating on Bigby's Hand)
Balian (leechy)
Shale (leechy)
Lair
Aboleth (28 damage, 10' down)

Celric is up; need a WIS save from Flynt

(Okay... It's time to burn some sage and have a seance to remove this bad dice mojo.)

Celric climbs down the rope at his normal speed when reaching his last bit of movement he lets go of the rope. Celric focuses his energy on the aboleth and casts harm 

damage roll 53

Quote from Esker >>

Squiggles:

Haste and Bigby's are both concentration spells, so if you cast haste it will end Bigby's

What square are you wanting to end up in?

 

Gah, I somehow missed that even though I actually went looking to see if they were both concentration. Instead of Haste i'll go with Mirror Image

Am I disengaged? I'll go to V9 if I can do so without AoO

Squiggles: The aboleth is within 10' of you, so is currently threatening you. However, V9 is still within its reach (according to fantasy diagonal geometry), so you can move there without an AoO.

Aboleth CON save vs. Harm: 18

As Celric's spell takes hold in the aboleth, its already flaking flesh begins to disintegrate further, as bits of skin float up to greet Balian and Squiggles. Although it manages to resist the full impact of the spell, it still sustains a serious blow (26 damage), enough to disrupt its concentration on the mass illusion affecting Balian, Shale and Jarl, who no longer feel the leeches on their skin.

The aboleth responds by lashing out in fury at Balian with its tail (legendary action #1)

Attack: 10 Damage: 12

managing to overcome the thief's evasive maneuvers.

Waiting to see what happens with Flynt before Brix takes his turn.

It just adds insult to injury that not only are you collectively rolling terribly, I'm also rolling really high (aboleth's concentration save notwithstanding). This should by all rights be going better for you than this.

Flynt Wisdom Save - 10
