looked up fury, found two things, a greatsword and an ED.
Kinda off topic, but the greatsword had Wounding. Does wounding stack with itself, i.e. if I hit someone 3 times with a Wounding weapon will they take 3 CON damage?
Fury as mentioned was the ed, with wounding yes that is the way it works it stacks but as you get higher and higher level mobs get more and more resistant to it, eh difficulty and higher there's no point in using such a weapon.
