The Hack and Slash perk in the One-handed skill tree says that
Attacks with war axes cause extra bleeding damage
What is bleeding damage?
Is it instant or damage over time?
Do undead take bleeding damage?
I love the flavor of using war axes but I want to know more about this perk before I take it.
Bleeding damage is a damage-over-time effect: each rank in Hack and Slash will do one to two extra points of damage every second for a few seconds. It’s essentially a fast-acting poison.
As in Morrowind and Oblivion, undead like skeletons are unaffected by poisons and effects like these.
