Balassar tightens his grip as he prepares for the fight ahead.

Balassar initiative:4

Round One:
Alton
Zombies
Balassar
Rhane

Alton is up first. Alton, with your clear view of the room, the magical light and your high passive perception, you can see there are at least four more zombies prone on the ground. There may be more further into the room.

Alton aims his hand crossbow at the only zombie that is standing up and fires. "There is at least five of them in there."

Movement: None
Action: Fires a crossbow bolt at Z1. Attack: 26, Damage: 10 Piercing

Alton hits. The arrow sticks in the zombie's stomach.

Zombie 1 drags itself over to the door, while the other zombies clamber to their feet and start to follow. With the doorway acting as a bottleneck, only Zombie 1 is able to make an attack against Balassar, trying to slam into him but missing (21 against AC).

Balassar is up.

Balassar snarls, as he evokes the strength of giants, the silver glint of his dragonborn scales catching the light as he pivots on one heel.

"Then we cut them down one at a time."

He brings his scimitar in a swift arc, the blade humming through the air with practiced precision, aiming to cleave into the rotting flesh of the zombie that dared lunge at him. He then lashes out in a follow up arc.

“Back to the dirt with you!”

OOC:

Bonus action: Giant’s Might

Attack 1: 10 to hit for 9 damage

Attack 2: 14 to hit for 10 damage

Giant’ Strength Damage: 2 additional

Zombie 1 takes a solid hit, and another, and on the second it goes down... and does not get up.

Rhane is up.

Rhane:

With the wall between him and the nearest zombie, Rhane steps to the west to clear his lines of fire and aims carefully through the door at zombie Z3.  Rapidly firing again, he shoots at Zombie Z5!

(Move 5 feet to the west, then hunter’s mark on Z3.  Sharpshooter and Hordebreaker to fire the two arrows.)

Sharpshooter Longbow with Hunter’s Mark on Z3:  20 to hit, 21 points damage.

Sharpshooter Longbow on Z5:  16 to hit, 22 points damage.

Rhane is on fire: Zombie 3 is hit and almost goes down. Zombie 5 goes down and stays down.

Round Two:
Alton
Zombies
Balassar
Rhane

Zombie 3 is injured, Zombies 2 and 4 are uninjured.

Alton is up.

Alton will move up to where Rhane use to be and fire off another crossbow bolt to try and finish off one of the zombies.

Movement: Moves five feet to the north next to the door
Action: Fires a crossbow bolt at Z3, Attack: 20, Damage: 7 Piercing.

The bolt hits; the wounded zombie sways on its feet, about to collapse... but it remains upright (made its saving throw).

The three zombies surge through the door, each making a single slam attack:

Zombie 3 on Rhane: 13 against AC, miss.
Zombie 2 on Alton:  12 against AC, miss.
Zombie 4 on Balassar: 21 against AC, miss.

Balassar is up.

Balassar swings at the zombie in front of him twice.

OOC:
Attack 1 on Z4: 12 to hit for 9 damage
Attack 2 on Z4: 9 to hit for 10 damage
Giant's might additional damage: 6

And so Zombie 4 goes down.

Rhane is up.

Rhane:

Still holding his bow, Rhane kicks at his Hunter’s Marked foe, Zombie Z3.  Starting with a a low sweeping kick aimed at its thighs, he follow up with a reverse direction elbow to its neck!

Unarmed Monk Strike with Hunter’s Mark:  Attack: 25, Damage 10

Bonus Action Strike Again:  Attack: 10, Damage 8

(re-rolled in discord): 25 to hit for 10 damage and 10 to hit for 8 damage

A kick and an elbow, both connecting. The kick brings down Zombie 3, so Rhane moves to strike the last remaining zombie, Z2.

Round Three:
Alton
Zombie 2
Balassar
Rhane

Alton is up.

Alton switches from the hand crossbow to his rapier and moves up five feet to take a stab at the last zombie. After that, he'll move back five feet into the corner. 

Movement: Moves up five feet to be in the doorway, and then moves back into the corner.
Action: Attacks Z2 with the rapier, Attack: 11, Damage: 12 Piercing

Stab! A squishy hit, but the zombie is still up.

Slam! The zombie slams into Alton, with a natural 20, for 10 points of bludgeoning damage. It doesn't move otherwise.

Balassar is up.

Balassar moves into the doorway to swing at the creature twice.

OOC:

Balassar moves 5 ft into the doorway

Attack 1 on Z2: 16 to hit for 9 damage

Attack 2 on Z2: 12 to hit for 6 damage

Giant’s Might Damage: 2

And with Balassar's first strike, the zombie goes down. Combat is over.

Beyond the doorway, you see into the large room, the floor strewn with further bodies that don't appear to be moving, and a pile of more corpses in the corner. It doesn't appear to have much in the way of furniture, and the stench is truly awful.

Rhane:

Careful of any hidden traps or scavengers among the bodies, Rhane thoroughly searches the room for clues, treasure, or hidden exits.

Perception:  29

Rhane walks into the room, slowly and carefully...

Several bodies near the far wall jerk to life, so to speak. Jerk to movement, at least. And there is a growl from the corpse pile.

We will keep the same initiative order, but this is Round One of the new combat. You can see the five zombies that have been stirred up - they are prone - but you don't see the growling creature in the pile to the north-east of the room.

Alton and Balassar, if you feel you would have followed Rhane into the room, you can move up to ten feet to reposition yourself before starting.

Round One:
Alton and Balassar
Zombies 6, 7, 8, 9 and 10
Rhane
??????

Alton and Balassar are up.
