The map scale is 5ft. The white space (horizontal) is just there to make the map look cleaner. It's terrain is the same as the terrain surrounding it. 
Floor(-); Debris - Gives half cover (¬); Doors (#); Walls (=);
I did not draw the full map as I did not deem it necessary. I will add to the map if you move out of bounds (like going through the doors into places that haven't been drawn)
If something is colored orange, it means the thing is unconscious. It may or may not be rolling Death Saves. 
If something is colored pink, then it is dead. 

I just remembered zombies 5 and 6 are blinded by Color Spray. So, Zombie 5 actually misses while Zombie 6 doesn't get the crit. Updated Creature's character sheet with appropriate damage.

OOC: Didn't realize you could keep track of hp there. Pretty cool!

Tiger-Creature attempts to finish off Zombie5.

Bite attack: 22; damage: 9 piercing damage

Zombie5 is dead. Choose a different target.

Oh, I see. Zombie1 then.

(Speeding up this section cause I'm going to bed)

Arcon's death save: 20

Arcon's senses return to her. She is lying prone.

Creature bites down hard on Zombie1.

Arcon's turn.

Archon disengages and heads as far away from the zombies as possible.

Arcon is unable to get very far.

Zombie6 Slam VS Creature: 17 (Adv: 10) Dmg: 7

Zombie1 Slam VS Creature: 5 Dmg: 7

Zombie3 Slam VS Creature: 7 (Adv: 22) Dmg: 5

Zombie2 Slam VS Arcon: 15 Dmg: 4

Claw Zombie VS Creature:
Attack VS Creature: 13 (Adv: 8) Dmg: 3
Bonus Attack: 20 (Adv: 7) Dmg: 1

Zombie2 Crit damage: 4

Arcon tries to run away but Zombie2 goes after her and smacks her at the back of the head and she goes down again. The Claw Zombie goes to join the dog-pile on Creature. It manages to get a scratch off while the other mutants' hits bounce off Creature's thick tiger hide.

Whispers, Creature's turn
Arcon's Death Save.

Another attack vs. Zombie1.

Bite attack: 20; damage: 7 piercing damage

Creature bites into zombie1. The mutant manages to stay standing... but just barely. A strong wind could probably knock it down at this point (2HP left).

Whisper's turn
Arcon's Death Save.

Whispers turns her hex toward Zombie2 (which is still near Archon yeah?) and fires another beam at it, "Crap. Crap."

Attack: 18 Damage: 19 + 6 necrotic

Whispers hits the mutant who had so far, somehow avoided the scorn of all the heroes up to that point.

 Arcon's Death Save AGAIN: 7

Zombie6 Slam VS Creature: 18 (Adv: 17) Dmg: 6

Zombie1 Slam VS Creature: 9 (Adv: 11) Dmg: 5

Zombie3 Slam VS Creature: 17 (Adv: 22) Dmg: 4

Claw Zombie VS Creature:
Attack: 7 (Adv: 6)  Dmg: 5
Bonus Attack: 8 (Adv: 23) Dmg: 3
Crit Damage: 2

Zombie2 Slam VS Whispers: 22 Dmg: 2

The dog-pile gets too much for Creature as he reverts back and is promptly knocked down.

The Mutant that brought down Arcon move to Whispers and attack her but it misses.

Whisper's Turn.
Arcon and Creature: Death Save

(DM: What is going on here? I put this encounter on an encounter calculator and it said it was a "Medium/Hard" (NOT Deadly) encounter. In my other campaign, I had 4 PCs defeat Deadly encounters (according to the same calculator) with some difficulty. This wasn't supposed to be a TPK but it's turning into one.)

(If this is 6 zombies and a ghoul, it totals up to 1500 xp, which is deadly. 500 from the monsters, x3 from party size and amount of monsters)

(It's 6 zombies and 1 zombie with daggers. No Ghouls here.)

(Well, at first we couldn't hit anything. And they had us surrounded so had advantage on everything and the two ranged attackers had disadvantage. Then a bunch of nat20s.)

Whispers is running (disengage). She can't haul both of them out, she'll die trying against the remaining five and the claw guy who gets two attacks. (shrug)

You have a big enough head start so you can escape...

Arcon and Creature: Do you want to make new characters or do you want me to try and find some way to try and keep you characters alive longer?
While you are deciding that, Whispers, where are you going to go?

As for me, I'm going to go and review this battle and see what went wrong.

(I'd like to keep Archon, if possible.)
