As Falynn blesses Hansel, the zombies strike back.  They drop their box of rocks on Nessie (I misread it as both of them having one).

Dealing 5 bludgeoning damage, DC 12 Dex save to negate.

Hansel then swipes brutally at the injured zombie (11), and drops it to the ground.

The remaining zombie drops down off the ledge, taking 5 damage from the fall.

Dex save: 8

EDIT:: Nessie confidently tries to move just out of the way but maybe a little too confidently as her wing get clipped and causes her to slam into the cave wall. She looks barely conscious from the hit. 

(If the zombie is dropping down off the ledge so I get an AoO since I’m flying in front of the ledge? Hail Mary ask here lol)

(The one that fell is still alive, right? And most of the party is still on that lower level, with the exception of only Nessie, correct? I'll send my message with those assumptions, and if I'm wrong, I'd ask to possibly change it to something else.)

Falynn sees the zombie getting closer after tumbling its way down the ledge, and reactively pulls out her scimitar and slashes across it in a swift motion.

Attack: 20 Damage: 7 Slashing

X'rax

When it's X'rax turn again, he'll draw his sword striking down the zombie with a wide swing at his chest.

  Attack: 18 Dmg: 13 slashing // on movement 2 Thunder

(Nessie would not get AoO, as the zombie doesn't leave her melee range.)

(Falynn, those assumptions are correct.  All four of you are surrounding the zombie, currently.)

Falynn slashes at the zombie, scoring a solid hit.

X'rax swings at the zombie, but trips over his robe.

(Nessie)

Nessie tries to muster the rest of her strength and tries to fillet the zombie. 

Dagger attack11 Damage4

Sneak Attack:3 (due to everyone  thanks y’all)

Offhand dagger attack 25 damage:4

Both of Nessie's attacks connect, leaving the zombie barely upright.

He attempts to swipe back at Nessie . . .

Attack: 21 Damage: 5

And lands a brutal blow, knocking Nessie to the dusty cave floor.

(Hansel)

Nessie slumps to the ground unconscious. 

X'rax

"Someone needs to help her. The X'rax will hold the zombie at bay." X'rax swings again.

Attack: 20 Dmg: 14 additional thunder on movement 7

X’rax delivers a brutal blow to the remaining zombie (19), but it just barely manages to shrug off the blow.

(Hansel, Nessie death save, Falynn)

Death save: 12

Falynn puts her sword back into its place, and holds one of Nessie's arms, before casting Cure Wounds to get her back up.

Healing for: 11

Nessie is returned to the world of the living by Falynn.

(Hansel, Nessie)

Nessie rises, spreads her wings wide as if she were stretching after a good long nap. Sees the zombie standing in front of her. Her eyes get wide and she attacks  

Dagger attack6 Damage6

Sneak Attack:1

Offhand dagger attack 16 damage:1

Nessie stands up, hits a wall, and then hits a zombie (10).  The zombie still manages to stay upright.

(Posting for Hansel, he's been inactive for a while.)

He'll unload both attacks on the zombie.

Attack: 14 Damage: 4 Crimson Rite: 2

Attack: 11 Damage: 4

(My own rolls scare me sometimes.)

The zombie takes one brutal, flaming blow to his face (4), and drops to the floor.  You are now out of combat.

Everyone is still on the lower level, and you can't quite see over the ledge.

Nessie says, “thank you” as she flies slowly up to try and just barely peak over the ledge. She lights a torch and listens for the sounds of any other creatures and looks for any possible traps the cave may have in place

Perception: 11

(Thanks for doing that, sorry I just started a new job and I've been busy at work).

As Hansel goes up the stairs, he is also going to listen for any signs for potential foes - 16

Hansel hears nothing.

You haul yourselves up onto the ledge, and find yourself in an open room, about 40 feet by 40 feet.  There's a passage to the right that continues for a bit and then turns left, and a passage to the right that goes straight and seems to open up ahead, although you can't make out any details.

(Did you see my perception check? -- just curious if that elicited anything.)

"Hmm, what do you guys think? That way seems to open up, but we might get a better idea of whats going on around here if we take the other path."

X'rax

 "Given the lack of Information the X'rax thinks the decision at this point is irrelevant, we just should stay consistent. So if the Nessie feels better let's take the other path." X'rax starts to head of into the passage.
