The new Bloodrage causes the owner of the buff to take and deal 40% more damage, regardless of how it is dealt. The skill also has a short enough cooldown that you can have it up on two targets (I use -wtf mode to make it a little faster in this video). If you have it on both yourself and the target, you will reflect 384% of the damage (incoming damage * (1.4^4)) damage back to your target.
