(Yes, I believe that you attack did hit, but the numbers remain about the same with the extra bodies being added from inside. Marion, Dajur, Genghis, and Devon, you may now make your attacks/actions)

Dajur throws another firebolt (attack 12 damage 1 ) and attempts to back away from the house to keep distance  for ranged attacks 

As he moves, one of the more alert shambling zombies manages to pull off an opportunity attack

Attack: 5, damage: 3

Dajur sees the swipe and keeps backing as it misses.  He calls to Magnus "got a problem here...come smash"

(Merry Christmas everybody! Enjoy this time with your families, friends, neighbors, or whoever else you see today.)

Throwing caution to the wind, Magnus turns and sprints around the corner, moving remarkably quickly for someone his size. Seeing the undead pressing out of the house he lets out a guttural roar.

ACCURSED UNDEAD! BEGONE!

Extending his halberd to the edges of his reach, he swings over the heads of the rest of the party, bringing the weapon down at an angle with murderous intent, eyes sparking as he aims to use both the blade and the shaft.

Attack: 7

Damage: 12

(Merry Christmas!)
