As soon as Cadence falls off the brige, Velda rushes forward, ready to defend her friend in case something or someone was waiting to attack. Upon seeing her float gently to the bottom of the pit, she relaxes somewhat, and at the sound of her finding something down below, she even cracks a grin: "I will never understand how someone so chaotic as yourself can believe there's a plan for everything."

Fionn is still covering the room with his crossbow

Cadence stops abruptly and glances up at Velda.  Then she cracks a winning smile at her and winks, before returning to looking at the chest. 

Con Save : 3

As you make your way to the chest, a one-eyed spiny creature emerges from behind the pillar on the west side of the crevasse near the collapsed bridge. It’s gaze fixed upon Cadence. 

 Cadence goes down from the creatures Rotting Gaze. 

Fionn fires at the creature

Attack: 13 Damage: 2

Initiative 10

Fionn your bolt hits the creature, though from your vantage point you can’t see Cadence. As the bolt strikes the creature your mind is filled with shrieking and howling. 

Seeing Cadence suddenly collapse, Velda shouts: "Cadence is down!" before leaping into the pit to face the creature herself.

Acrobatics to avoid falling damage: 20

Initiative: 21

Rathe ducks around the pillar to try to hide with her bonus action if she was not already hidden.

She pokes back out from the other side, draws her bow, sets her sight on the creature, and fires at its eye.

Longbow Attack: 12 Damage: 6 plus 2 sneak attack damage if that is applicable (I did not roll with advantage)

 Stealth if needed: 9

Adv attack: 23

Spider Nova would blink. She had seen the threat but had no time to react before all hells broke loose. Though, she should be used to it by now right? With a spider sigh, Nova would pad her way over to a big eyeball.

Initiative: 9

She'd try to spider bite its cornea.

Attack: 11 Damage: 3 + 5 poison on hit

Fionn moves to a position where he can see Cadence

shoots the Nothic again:  Attack: 13 Damage: 2

then casts healing word on Cadence healing 6

Rathe Initiative: 7

Cadence death initiative : 17.  She's dextrous even when unconscious!

First death save : 14

Rathe’s arrow finds its intended target, striking the beasts eye. The moment it does so Rathe’s mind is filled yet again with shrieks of pain and howling.

Fionn’s second bolt towards the creature goes slightly wide, hitting the natural stone pillar it had been hiding behind. Then mutters a few words under his breath to the lady and Cadence is brought back to consciousness.

 Nova who was already making her way up to the ceiling when the cries of Cadence is down occurred, skitters along the ceiling and jumps down towards the Nothic and catches it near the eye with one of its mandibles. From what you can tell, it doesn’t seem like the poison had the effect you were hoping. 

Seeing that the Nothic wasn't down below, but instead across the chasm, Velda rapidly climbs up the other side of the chasm, and, hiding her face from it's gaze, grabs her longsword with both hands and slashes at the creature.

Velda’s attempt at shielding her face from the creatures gaze seems to have worked, though sadly her attack misses the creature completely and she hits nothing but air. 

(waiting on actions from a recently healed Cadence and Rathe. Then I’ll post for the creature)

Rathe pulls another arrow, stilling her horror at the creature, nocks, draws, and fires all in one movement.

Attack: 16 Damage: 9 plus 5 sneak attack damage thanks to allies in melee

If she can move two spaces north and crouch down to hide against the wall, she'll do that.

Stealth: 14

Rathes arrow flies straight and true, finding the creatures flesh and causes everyone’s head to fill with shrieks and howls of pain. Though Rathe doesn’t see it land since she is already pulled behind the pillar, waiting for another opportune moment to strike again. 

(Need an action from Cadnece now.)

Cadence's eyes blink open after the horrid rotting gaze of the creatures nearly killed her. She stands up, a little confused, but realizing all of her allies are still fighting the creature.   A bit muddled still she manages to pull together some basic magic and fling a firebolt at the thing. 

Attack: 15 Damage: 6

The creature turns its attention to the spider that just bit it and swings one of its claws at it and the other claw swings towards Velda. 

 Spider Nova skitters just out of range, easily avoiding the claw swipe while Velda’s shield is perfectly positioned for the creatures claw to clang off of. 

Round 2, Fight!
