Yong spins to face the troll and either not hearing Durnan or just panicking, shoots a ray of frost towards it.

Attack: 19 

Damage: 1 Cold 

The troll, its wounds closing as it steps towards Yarga and bites her Attack: 20 Damage: 7 and bats her aside with its claws Attack: 17 Damage: 9 Attack: 23 Damage: 13

Allian's turn

Hoping to buy people time and having no fire attacks himself (silver=cold breath) Allian positions himself trying to angle his spell thunderwave con dc 14 damage 3 so it doesn't hit anyone but the troll hoping to send it back into the pit then he runs. If he doesn't see a way to do that he sends a healing word to Yarga as a bonus action 7 and disengages looking for a source of flame "Run!"

For fire, the tavern is lit with torches and lanterns. Troll's CON Save: 24

Stirge's CON Saves:

1: 17

2: 11

3: 6

Note: i edited the post for a typo and it changed the rolls the troll failed and all stirges but 2 succeeded

The thunder throws the troll back into the pit as it falls into the undermountain from where it came. Two of the stirges are thrown back, but being the larger of the group survived, where the other one, the smallest falls to the floor with a splat. One of the remaining stirges flies at Yong and tries to attach its self to his shoulder, Attack: 18 Damage: 7 if this hits the stirge is now attached and draining Yong's blood

Iyler's turn

ok I accidentally skipped Cassiel, its his turn now I guess

Cas a bit shocked at the trolls demise rallies his wits and launches a Sacred Flame at the final target! 

DEX Save: 14

The stirge dodges the target. Yarga takes out her crossbow and shoots it at one of the stirges attached to Iyler, Attack: 4 Damage: 10

Meanwhile durnan fires a crossbow bolt at the other one, Attack: 18 Damage: 14

Durnan kills one of them, Allian's and Yong's turn.

Allian looking at the stirges waits till he can get them in a cone of 15ft and a breath of Icy cold emits forward from his mouth 6DC12con

If all thats left is the one attached to cass he pulls it out athletics 12 then breaths on it.

Yong shoots another ray of frost towards any living enemy.

Attack: 19 Damage: 8

You pull the stirge of Cass and breath an icy breath on it, as chucks of ice crystalize around it. The last stirge is dead.

Allian pulls out a torch and looks for a source to light it if he cant find one he uses his tinderbox lights is and tosses it down the hole just incase

He looks at Duran 

"Fire, right?"

Durnan looks at Allian while chucking a lantern down the well. "Yes"

Allian smiles a toothy grin "So did I earn an ale or two? I work for beer." He chuckles then turns to see if anybody needs healing (Supposing I still have one spell left if Yarga didn't need it I send it to Cassia 8 If not I roll a medicine check 8)

Then he walks to Yarga to help her with her wounds "What was that about?"

note I only have two spells a day right now.
