I was wondering how exactly does the bloodthirsty character trait work. Description states that every kill by that character will be a fatality if weapon allows it. What does it mean exactly? I am assuming that it means head chopped off. The problem is, I have used both 2-handed axe and 2-handed sword and I definitely chopped off heads with the sword before, yet this time it was just a normal kill. Is it a bug, or am I missing something obvious? The second part of the question is: if the head flies, is it more scary for the enemies in the vicinity, or is it just useful to prevent resurrecting by the necromancer or zombies coming back to life?
