The two passive slots along the bottom path leading from "Bog Bodies" to "Toxic Emanations" are now both named "Muscle Stripped Raw" with the tooltip reading: "Each time you hit an enemy, you receive an "Unleashed Fury" point. Each "Unleashed Fury" point increases your attack speed, life leech and reduces your all resistance score."

The tooltip in both those passive slots which are both named "Muscle Stripped Raw" is tooltip for the "Child of Fury" passive tree "Flurrying Flames". I think those passive slots used to be +% Toxic Damage but not entirely certain.
