Jecob will follow what the others decide.
He is currently pouting at getting shocked by the fish, then it going belly-up before he could get more payback.

I think I have you all in a decent order right now.  Two swarms of eels come out of holes in the cave walls and attack, each eel having fire red eyes.  One will attack at Kraven, this one comes all the way out of the wall, the other stays in the wall but pokes their heads out to take a bite a Varlan.

Kraven- 11 to hit, 6 piercing damage, and a con save DC 10 or take 10 poison damage, 5 on a success

Varlan- 19 to hit, 7  piercing damage, and a con save DC 10 or take 9 poison damage, 4 on a success

You all may take your turns.

"Oh come ON," Mist exclaims. "All this for a beedin' rock?!?"

Eldritch blast @ the nearest eel swarm (gold/red) - Attack: 11, Damage: 5 force

Blast #2 - Attack: 13, Damage: 14 force

Kraven squawks in alarm as the eel barely misses him and then tosses some psychic daggers into the mass of writhing eels. (blue)

Psychic Dagger: To hit natural 1

Corpse Psychic Dagger:  To hit 18 with 9 damage

Sneak Attack: 8

Mist's blasts hit the rock wall and send some stones to the ground.

Kraven's first dagger misses, hitting into rock, but then flying back to him but the second dagger takes out a good amount of the Eels.

Jecob: "I could try Speak With Animals ... except I have no idea how to be an eel diplomat."

The eel swarm that attacked Varlan retreated back into the wall?
Maybe several inches of ice over the openings will keep them at bay.

He casts Shape Water to create an ice wall in front of the wall where those eels are hiding, 10' by 10' by 1.25', anchored to the wall and plugging up the holes.
(Cannot target water with creatures in it, but they are staying inside the wall.)

Varlan curses as they are once again taken by suprise. Spinning around quickly, he strikes back at his attacker.

Attack 1: 20; Damage: 9
Attack 2: 9; ---

If the first attack hit, then the eels are at disadvantage attacking anyone else.

Jecob your Ice plan seals them into the wall.  There are several holes but all of the ones near where they came out at are now covered.  That being said every few feet there are more clusters of holes that are the same sizes as the ones Jecob covered.

Varlan I moved you and your attack to the one that is out in the open.  It hits some of the eels, and over half of them are dead now.

The remaining eels will take their bit at Kraven again.  25 to hit 6 piercing damage, and a con save DC 10 or take 10 poison damage, 5 on a success.

You all may take your turns.

((@DM: If the eels were hit by Varlan, then an attack against anyone but Varlan is at Disadvantage ))

Kraven Con Save: 12

Kraven lifts his arm up to ward off the attack and thankfully the eels seems to be distracted with the feathers as the strike barely missed.

(@varlan thank you for the reminder)

Disadvantage roll is now 15 to hit.

I am waiting on everyone (really just one or two attacks to hit), I am going to wait till about lunch time then I will post again.

Kraven will disengage and move back a step while summoning his daggers to once again throw at the remaining eels in front of him.

Psychic Dagger: To hit 22 Damage 9

Sneak Attack: 15 Damage

Kraven's dagger cuts through the last of the eels before disappearing.

We now have path G, H, and I.  You also are welcome to go back and try one of the other 4 path ways we have not gone

G looks to split after a few feet.

H looks to open to a room that green light is coming out of.

I you can only see more path way.

Kraven will shrug his shoulder and hope for the best with the fighting that just finished as he creeps northward several feet to check out the room with the green light,signaling the rest of the group to not move and hopefully not make any noise.

He will also whisper into the minds of Mist, Kuatho and Varlan to hold still a moment while he goes and checks. (Psychic Whispers - next 7 hours you can mentally talk to me and then I can relay message back and forth)

Stealth: 28

Perception: 24

“Do you see anything?”  Kuatho thinks back as he holds still, but looks down the pathway of G.  He comes out of the stunned effect and wiggles all of his limbs and both antennae to make sure they move.  

Shimmering, green portals line the sides of the cavern. A hezrou guards this chamber.

I uncovered it in roll20.

Quote from coachmanak >>

A hezrou guards this chamber.

(Glad Kraven suggested that the others remain still and silent. I suspect that Jecob would have blundered his way into danger with a bad Stealth check.

He isn't covered by the Psychic Whispers, so make clear if he remains clueless about the situation.)
