Curascious jumps off he traps and fires off an experimental cantrip!

5 Poison Spray!

Coming up with a sort of poisonous smoke plume, Curascious quickly directs the spray at the troll. 

// The troll must make a DC 13 CON Saving Throw or take 10 poison damage //

Herd charges in, also focusing on the troll, alongside Tith...

With a torch still wedged into his shield, providing him light to see, he swings at the troll with his warhammer!

// Attack: 15 Damage: 13

Mozu just squints and raises his upper lip in a sneer of disdain at the troll, “Wretch.” He raises a hand as it boils with radiant energy. He flexes it and a Guiding Bolt releases toward the troll! 

Initiative: 18

Guiding Bolt: 8 for 11 radiant damage + advantage on the next attack.

The Flood Troll catches Tith's ax in her meaty hand and cackles. "Is ki ven davra ven yeri laz hash naqis mahrazh?"

As she laughs Red hits her in the side and as she turns to see where it came from he is gone. Then she is hit by the poison spray. She coughs and growls and then is hit by the guiding bolt and warhammer. The Troll is hurt badly but still standing.

The Troll swings wildly at Tith:
Troll Claw Attack: 12 Damage: 7
Troll Claw Attack: 19 Damage: 8
Con Save: 26

She shrugs off the poison spray with no effect.

Daktani steps from behind the troll takes a swipe sees the pummeling she is taking, turns stark white and runs, he turns the corner and is gone from site.

Herd, seeing a glowing halo surrounding the troll takes a massive swing with his warhammer! 

After he swipes at the troll, he comments, "Should we be concerned that the troll's friend may seek help?" 

// Attack: 16 Damage: 13

The troll is rocked but still stands.

Red takes another shot at the troll from the corner then returns to cover.

Attack: 18 Damage: 14

Stealth: 24

"WEAK! C'MERE ORCY IMMA CHOP YA!!!" Tith yells in frustration and charges in the direction he thinks the half orc went, if he sees him he will throw an axe at him if a dash doesn't get him in melee range

As the Troll falls lifeless with that last hit Tith runs into the next room searching frantically and sees:

Embedded into the floor of this chamber is a ten-foot-diameter granite emblem of a faded gold and white longsword. Four passages lead out of the chamber in different directions. A portcullis blocks the southern exit, and a sturdy wooden door leads west. A ladder in the southern corner of the room leads upward, and a small chest and decrepit bookshelf face one another from opposite walls.

 But the half-orc is no where to be seen.

Rolling a d4, 1 tith sits and pouts. 2 he checks ladder, 3 he checks the door, 4 he smashes the chest open

2

The ladder leads up to a closed trap door in the ceiling.

Red checks the chest for traps.

Investigation: 19

// ugh //

Red opens the chest.

The chest, contains much of the loot Daktani has vengefully stolen from Trunauans over the years as well as some items Skreed gave him for safekeeping, including 1 ounce of sovereign glue, 2 doses of universal solvent, 50 feet of silk rope, a disguise kit (with 6 uses remaining), a set of thieves’ tools, a noble’s outfit worth 75 gp, a signet ring worth 50 gp, and coins  totaling 237 gp, 155 sp, and 55 cp.

Herd leans over and whispers, "Perhaps Mr. Flumplestump recognizes the signet?" 

Curascious catches up, jogging as fast as his legs can carry him. “Allow me?” He tries to get a good look at the signet. 

Mozu is going to keep watch on the troll’s body for a few moments.

The signet ring is fancy and obviously stolen from someone with money but Curascious doesn't recognize the signet. It is very well made and worth quite a bit for a non-magical ring.

The Trolls body is a mangled mess, the party really did a number on it. Mozu can see, other than it's torn up clothes it doesn't appear to have anything on it.

Mozu checks to see if there is any regeneration going on with it, never hurts to check with trolls.

No regeneration that you can tell.
