(Athletics with advantage: 13)

Morgan and Rashar are able to undo the barricades and the door is revealed. Renaer gasps. "Well done. Now, let's see what's on the other side, shall we?" Renaer says, as he keeps his rapier in hand, gradually opening the door to peer inside.

The room revealed is a lavatory, this room has a hole in the floor that opens into a cesspit. You immediately notice the corpses of two goblins, and some gear they had that appears to have been deteriorated, as if corroded by acid. Inside the hole, is a gray ooze that's trying to get out of the hole. How does the party react?

Rashar's combat instincts kick in and without hesitation he immediately fires his crossbow at the gray ooze. 

Attack: 20 Damage: 7

"I'll not let my hammer hit such a thing!" Yells Grykham as he drops it into a loop on his belt and slings his shield over his back.  He draws the short bow and, knocking an arrow, fires at the ooze.

Attack: 10 Damage: 3

Krivnaar throws up a little inside his mouth at the sight, before composing himself and readying for battle against the rather unsanitary ooze.

Initiative: 3

Rashar and Grykham eagerly barge into the lavatory, seeking to dismantle this ooze rather than lock it up like Zemk and Krentz were attempting.

Jarret
Ooze: (AC: 8)/(HP: 22)

First will be Morgan. The gray ooze is already within melee range.

(Is it in melee range of Morgan, as he is still outside of the room...)
Morgan pulls out a javelin and throws it at the thing...
Attack: 12 Damage: 7

OOC: Oh whoops, I put Mo where R is supposed to be, lol. I'll fix that.

Morgan hurls the javelin at the ooze, and the javelin ripples through its gelatinous body. The metal tip of the javelin gets corroded from its acidic nature and it's no longer salvageable.

It now goes to Renaer.

Renaer will throw his dagger at the ooze, seeing as it has potential to dissolve metal weapons.

Attack: 24

Renaer
Grykham
Mardak
Krivnaar
Rashar
Jarret
Ooze: (AC: 8)/(HP: 7)

Renaer's dagger pierces the ooze's body, and the dagger gets corroded. (The dagger will take a -1 penalty on attack & damage rolls)

It now goes to Grykham.

 I preposted this or would you like a new roll?

OOC: Eh I'll keep it. Since you're in melee range, it'll be at disadvantage, so I'll roll that for you.
Just for future reference y'all, don't make attack rolls against something when initiative hasn't been taken yet.

The arrow tip is dissolved when the arrow lodges into the ooze's body.

It now goes to Mardak.

Mardak will cast Sacred Flame onto the gray ooze. DC 13 or it'll take 6 radiant damage.
Ooze's Dex Save: 13

The ooze, despite being in the sinkhole, manages to avoid being scaled by holy radiance.

It now goes to Krivnaar.

Krivnaar holds his nose as he lets out a torrent of energy that will hopefully quell the menace.

Eldritch Blast: 8 ; Force damage: 8

The Eldritch Blasts visiously pelts the ooze and its gelatinous body splatters all over the room upon impact. The ooze has been vanquished.

Admist combat, Krentz had awoken, and despite having been tied up, he was able to free his legs and he's bolted down the hallway.

Krentz Initiative:

Initiative Order:
Morgan
Renaer
Grykham
Mardak
Krivnaar
Krentz - (AC: 12)/(HP: 1)
Rashar
Jarret

It now goes to Rashar. Krentz is 60 feet away, but keep in mind that moving through allies space is considered difficult terrain.

Rashar sighs. 

"You're a tricky little bastard, aren't you?" 

He dashes past his allies, just managing to clear the corner of the hallway to see Krentz running away. 

Initiative Order:
Morgan
Renaer
Grykham
Mardak
Krivnaar
Krentz - (AC: 12)/(HP: 1)
Rashar
Jarret

It now goes to Jarret.

Jarret will follow Rashar, using his movement to run into the hallway. Once he is within line of sight of Krentz, he will reach past Rashar and murmur an incantation underneath his breath, casting fire bolt as a ball of fire blossoming from his fingertips hurtling towards Krentz’s back. 

Attack: 19 Damage: 6

Jarret is able to get behind Rashar, and casts Fire Bolt that zips past Rashar's head and pelts Krentz in the back. The bandit collapses to the floor.

Combat is now over.

Krivnaar hears the last grunt from from Krentz, and frowns as he looks at Renaer. "Well, so much for keeping that lout alive..." He then turns to the filthy room, and looks about in case there were any valuables left in here - though careful to avoid the corrosive remains of the ooze.
