Nalla will quickly begin her casting, hands moving in intricate patterns before with a final mutter she launches a Firebolt at the zombie closest to them.

Firebolt: Attack: 11 Damage: 8

Mr. Fists will move up and attack Zombie 1 with his short sword

Attack: 6 Damage: 6

Bonus Action

Unarmed attack. - Attack: 15 Damage: 4

Nalla, your firebolt hits the creature, turning much of the remains of its rotted flesh black and burned.

Mr. Fists, your first attack is wide and you almost lose your balance, but the second strike connects.

With Mr. Fists right there, Zombie 1 just thumps a fist towards him:

Attack: 10 Damage: 3

The agile kenku dodges it easily.

Sunshine and Verdan are up.

Sunshine moves to stand beside Telias, arrow nocked and ready as she falls into position. A quick breath, aim, and she fires at Zombie1.

Attack: 12 Damage: 4

Thunk!  Sunshine, your arrow pierces the creature's throat, though it does not seem to need it.

Verdan also shoots an arrow at Zombie 1:

Attack: 15 Damage: 4

It hits, and the zombie is looking badly wounded now, chunks of dead flesh peeling off and dropping to the ground where your arrows and fists have damaged it.

Zombie 2 shuffles towards Mr. Fists and attempts to slam its whole body into the kenku:

Attack: 19 Damage: 4

Mr. Fists, you take a zombie head to the chest, and it hurts!

Zombie 3 shuffles towards you as well, but comes behind Zombie 1 and just stands there aimlessly, unable to move further.

Telias is up.

Telias is up.

That's enough to KO Mr. Fists. 

Telias moves up beside Mr. Fists and lets out his spell. (rolled earlier) He then calls out to the monk and bids him to rise. Healing Word 4

Mr. Fists, you return to conciousness.

Zombie CON save:  10

Unfortunately, the zombie resists your spell.

Round Two
Mr. Fists and Nalla
Zombie 1
Verdan and Sunshine
Zombies 2 and 3
Telias

Mr. Fists and Nalla are up.

(Word of Radiance is everyone of my choice in 5 feet so the second zombie would have to make a save as well.)

(Thanks!  Zombie 2 CON Save:  16.  Sadly, also succeeded.)

Mr. Fists and Nalla are up.

Mr. Fist will hot zombie 1

Short sword Attack: 7 Damage: 9

Bonus action Unarmed Strike - Attack: 9 Damage: 6

Nalla will blast the next of the zombies that are closing in on them, another bolt of flame flying from her hands and towards the undead.

Firebolt: Attack: 8 Damage: 4

(OOC:  Sorry for those rolls!)

Mr. Fists and Nalla aren't able to land any blows on the zombies.

Zombie 1, clinging barely to unlife, slams again at Mr. Fists:

Attack: 8 Damage: 5

But clumsily, and without success.

Verdan and Sunshine are up.

Seeing that Mr. Fists is being positively bombarded by hits, Sunshine huffs and darts forward, drawing her daggers as she does so. She slips into the spot right in front of Zombie1 and lashes out with her daggers.

Attack: 16 Damage: 3 

Bonus Action: Offhand Attack: 5 Damage: 1

Sunshine, your first blow doesn't feel like your most skilled, but it connects.  The zombie...

CON save:  19

... seems about to drop, but some kind of renewed strength passes through it, and it remains standing.  You swing with your other dagger, and...

CON save:  6

... again, it seems to, not quite resist, but endure the attack.

Verdan attacks with his shortbow:

Attack: 16 Damage: 5

CON save:  7

Right through the head.  And this time, the zombie drops to the ground and remains still.  Zombie 1 is dead.

Zombie 2 slams its body against Mr. Fists:

Attack: 20 Damage: 4

And Mr. Fists drops unconscious again.

Zombie 3 steps over the body of its fallen comrade, without any sense of being aware, and attacks Sunshine:

Attack: 18 Damage: 2

Sunshine takes a headbutt to the chest and 4 points of bludgeoning damage.

Telias is up.

Telias uses the same combination as before, healing the monk while blasting out radiant fire with the same sentence. 

A: Word of Radiance DC12 CON or 5

BA: Healing Word 4

Zombie 2 CON save:  14

Mr. Fists wakes once again.  The zombie isn't injured by the spell.
