"What the?!" Shrek dumbfoundedly reacts to the attack, as the ample hair on the back of his neck stands at full attention (with fear and horror blazing through his veins).  He immediately responds by raising his new clawed hand in front of his face, more as a protective measure than a deliberate counter attack, but attacks back none the less-

Umber Hulk Claw Attack: 12 Damage: 14

Melchor makes a distinctive grasping motion, targeting one of the zombies. ‘Frigis…’ he mutters

(Chill Touch Attack: 23 Damage: 3)

Not more undead.

Randall takes a deep breath and then charges into the room.  He will target any zombie that looks to already have been wounded.  He stabs out with his spear.  Attack: 10 Damage: 6

Per usual, we will reserve his reaction to protect the first ally within 5’ to come under attack.

As Ankita takes in the room and sees the skeletons, she is just about to warn Shrek when he charges into the room and well, the zombies spoke for themselves.  She lifts her staff in a fighting pose and strides into the room, ready to crack the first skull.

Joining Randall to be able to flank, she swings her magically imbued staff..

 Attack: 25 Damage: 7

Randall dispatches the zombie Sandre was fighting with a solid shot to the head that send the zombie head bouncing across the room.

Melchor and Ankita punish the zombie Petra was fighting, damaging it heavily.

Shreks bronze claw slices a huge chunk of the zombies arm which is now dangling.

Dm roll: 16

Despite it's head bow being located a food 8 feet from its body, the zombie remains animated, preparing another attack

Olaerys strikes at another zombie with his battle axe, and if still up will give it a shove with his shield as a bonus action, trying to knock it prone.  If he dispatches the zombie, he will shove the next one in line.  

Battle axe : Attack: 18 Damage: 11 

Shove (with shield) : 12 

DM roll: 10

6

Olareys hews into Sandres zombie felling it, and then shoves Petras zombie too with enough force to finish it. Annoyingly, Sandres zombie pops back up again and attacks the bed threat:

Attack: 11 Damage: 6

Shreks zombie attacks him, trying to slam into him with its other arm.

Attack: 15 Damage: 2

2 other zombies go after Randall:

Attack: 11 Damage: 7

Attack: 6 Damage: 3

The last zombie clawing at Ankita:

Attack: 8 Damage: 7

Sandre continues to hack away, and Petra nips around the one attacking, flanking it:

Attack: 23 Damage: 6

Attack: 14 Damage: 7

Attack: 11 Damage: 11

Attack: 21 Damage: 13

DM roll: 14

Petra cleaves the head off her new opponent, it landing beside the other one. The zombie drops, motionless.

Sandre dispatches his zombie again, and once again it pop backs up.

(4 zombos left, 1 on Shrek, badly damaged, one on Sandre hacked to shreds, 2 on Randall, unhurt)

Shrek tries to grab the zombie attacking him and give it a nice hug with his claw-

Umber Love Claw Attack: 8 Damage: 19

Melchor makes a grasping motion towards Sandre's to put it out of commission once and for all... 'Frigis...'

(Chill touch: 21 Damage: 3)

DM roll: 21

Shreks love claw fills the zombies heart with....bronze. It is overwhelmed by Shreks piercing affections, so much so that after temporarily going limp, it reanimates almost immediately. "Brainnnnns" it says, as it looks beyond Shrek for a new target.

Melchors zombie drops with the ghostly hand hanging on to it

Ankita heads over to help Randall with the two he is wrestling with and attempts to whack at them with her staff, flanking it as she does...

Attack: 9 Damage: 5

Lol, forgot the advantage, here's the 2nd attack roll...  7

Ankita's magical club thwacks the zombie good, hurting it reasonably
