I didn't find this guy at all the first time I went through the quest. This time, I found one on my third turn in the charnel house (first two turns consisted of fighting a single ghoul and then failing to run away from a pack of three). So there must me some unlock but I'm not sure what.
I bound the ghoul king this time instead of fighting him, could be one difference. Also maybe got a different result from disturbing canvases? Don't remember.
You punch the ghoul for 4 damage.
The ghoul latches onto you and tears a chunk out of you with his teeth, dealing 5 damage.
You slam into the ghoul and deal 5 damage before he can fend off the attack, but the ghoul's sudden jump avoids all of the damage.
The ghoul leaps a shocking distance straight up.
You dive and tumble like an action hero.
The ghoul loops chain around you, creating a vicious trap dealing 21 damage, but you tumble out of the way, avoiding no damage.
The ghoul latches onto you and tears a chunk out of you with his teeth, dealing 12 damage.
avoiding no damage? :(
