( She's a bit disorientated, so no dashing for now.)

Ruven init: 9

Immediately, Ruven turns the lizard around and towards the blob. Using their connection, he reaches out into empty space, his hand wreathed in necrotic energy, when it suddenly disappears. The energy now wreathes the lizard, who runs forward to pass the spell along to the blob:

Attack: 22 Damage: 4

Jurgen initiative: 23

Clinging to the walls and ceiling, Ruven's lizard races toward the fight, and delivers a chill from beyond the grave to the horrid blob.

Jurgen is up next! (He is 40' from visual ranged and ~60' from melee; Draco the same.)

The blob is in bad shape after being repeatedly punctured, battered, and now arcanely withered. 

Jurgen runs/dashes with Draco to melee range

The blob again tries to batter Quinn:

Pseudopod Attack vs. Quinn: 19. Hit: 4 bludgeoning damage plus 5 acid damage.

Hearing the cry, Boona backtracks to the last fork. She watches Ruven's hand disappear to the north as Jurgen and his mechanical friend race by her.

Bryony and Quinn may act next!

Quinn takes another big hit from the ooze. He winces and curses as the acidic slime seeps in between his armor and eats at his flesh. He swings at the blob and curses as his mace clatters against the cave walls.

Quinn retreats up the tunnel to the north to create some space. 

Action: 9 to hit for 11 damage (9+2 from colossus slayer)

Movement: 30 ft north up the tunnel. 

Quinn manages to squarely strike this foul ochre jelly even with his sloppy, limited swing (AC=8)

It freezes, quivers for a moment, then goes still. The jelly is squashed.

Combat is over. Everyone may act.

Boona walks in, crouched over, a few seconds later, " What happen?"

Ruven shakes his head, muttering under his breath. For a long lost, abandoned mine, this place is teeming with adversaries. He'll send his lizard back north again, hoping to avoid any more surprises.

Quinn slumps his shoulders and breathes a sigh of relief. He looks back at Boona and shakes his head in the negative.

"I dunno what that was. I've heard tale of things like that which hunt and devour living things. Never seen one myself until now."

He kneels down and digs out his healing kit and tends to his wounds. Quinn then goes to inspect the jelly. He waves Lightbringer over the top of it hoping to illuminate it and possibly see its insides. Perception check: 13

DM: Can Quinn see any undigested items inside of the dead jelly?

(OOC: Used battle medic feature to heal 7 HP (5 on a d10 + 2) My healer feat allowed me to reroll my d10 hit die. All rolls in game log.)

Bryony looks at the remains of the gooey creature with interest. "I've never heard of a monster like this," she says. "A living goo. It's pretty gross."

Ruven's lizard finds nothing but blocked tunnels to the north.

Quinn finds nothing of value inside the gooey horror – just some unidentified bits of metal and a nail.

Where to? What next?

Bryony tries to step gingerly over the ooze but ends up getting some of it on her boots anyway.

"Ewwww," she says, but she continues to the east.

Boona waits for the others to go ahead before following...

Bryony pushes ahead to the east with her torch. Passages branch off in all directions. 

Jurgen stays next to Byrony .

"This place is way too big!" Bryony huffs. She heads straight down the passage but takes the first left (to the north) to see if there is a room there.

Ruven moves up with the group, the lizard climbing up onto his shoulder now. Ah, but if we could have only been here at its zenith he says in response to Bryony's exclamation. What a grand operation it must have been to have such expansion through the cavern system.
