Some updates to “Death of the Corpse Wizard”:
Skeletons now behave much more intelligently and will try to slowly break walls if they cannot find a path to you.
Brutes do twice the damage they used to the player.
Wizard bolts do not travel through walls. Using a bolt will cost you one health but give you one health for each monster it hits, so lining monsters up is the best way to gain ground in health/vitality.
