The portcullis groans as Sssyd raises it, to reveal a thin rectangular room beyond. Two doors are set into the west wall and stones are scattered throughout the room where the roof caved in.

Stealth: 21

Stealth: 8

Two zombies stumble from behind a pile of debris and shamble towards you.

Initiative: 18

Initiative: 20

11 initiative

 Initiative: 7

The cat jumps at the closest zombie, hissing to distract it while Aegean steps forward and stabs his rapier into the closer of the two zombies, green flames wreathing the blade as it strikes and jumping to strike the second zombie if the attack lands.

Green Flame Blade Attack: 10 Damage: 9, 3 damage to second zombie if the attack hits.

Edit: Forgot advantage roll: 6

initiative: 9

Before either you or the zombies can move, two arrows whistle out from behind a slab of stone, taking Aegean and Sssyd in the backs. (Surprise round)

Aegean: Attack: 23 Damage: 8

Sssyd: Attack: 21 Damage: 8

Behind the rubble looms a wight, it's eyes filled with a dead light. Initiative: 6

Initiative Order:

Aegean 20

Zombies 18

Wight 15

Donaar 11

Merzin 9

Sssyd 7

The zombies lurch forward to swing rotting fists at Donaar and Merzin. 

Donaar Attack: 16 Damage: 6

Merzin 10 Damage: 5

The wight hurdles the rubble blocking it's path and lands on Sssyd, dead fingers wrapping around his throat. Attack: 8 Damage: 5 (The target must succeed on a DC 13 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.)

It then draws a pale longsword and lunges for Sssyd again. Attack: 21 Damage: 7

The battlefield: 15 x 55 feet. Rubble where the ceiling caved in is scattered throughout the room.

Donaar!

Before Donaar can make another move, the door to the west shatters and a hulking half-orc fighter steps through the wreckage, followed by a human monk, a gnome wizard, and a 500-pound brown bear. They are about ten feet distant from Donaar and Merzin, and forty feet away from Aegean and Sssyd.

They will join combat beginning at the start of the next round.

Donaar!

Donaar, startled by the zombie attack, breaking his wildshape, casts Dust Devil behind the Bear, hoping it was strongest. (Sorry, I haven't been getting the Notifications from this for some reason. Putting the Dust Devil behind bear, and if I can, all the other people.)

Unless they're friendly, then Donaar will cast Shillelagh and attack the zombie with his quarterstaff. Attack: 21 Damage: 3)

(Sorry, I should have mentioned this: you will not be able to attack the rival gladiators nor they you until the next combat round.)

The zombie takes a quarterstaff to the head and it's skull caves in, spilling brains all over the floor. The zombie doesn't even blink.

Merzin!

(yoohoo…. Anyone.... are you there?)

Merzin swings his sword at the zombie.

Attack 16  Adv (from flanking) 15           Dmg: 8       Sneak Attack Dmg (from adv) : 5

''Hey guys, we got company!''

Zombie Constitution ST: 9

Merzin cleanly decapitates the zombie and it's head thuds onto the stone floor.

Sssyd!

Hissing at the wight attacking him, Sssyd swings his scimitar. 

Attack: 12 Damage: 5

Bonus Action:  Second Wind:  5

The scimitar connects cleanly but the wight takes no notice. 

Suddenly, in a flash of green light, Donaar is transported off the battlefield, and in his place stands a bewildered half-elf bard. Your Gladiatorium manager has just made a substitution.

Initiative: 22

"What the hell is going on here!"

And Seldor will stab the wight with his rapier and use a Bonus action to stab with his dagger.

Attack: 21 Damage: 4

Attack: 13 Damage: 3
