Brutality is an odd skill, similar to the Berserker’s Grief skill in the Defender’s right path. When capped, you have a 70% chance of channeling any damage you receive into bonus damage on your next attack. 70% is pretty good, even for Vegas. Say you hit for 2000 points of damage, but then you take 1000 points of damage. Chances are the next attack you land will hit for 3000 points of damage. While the prospect of getting hit is not pleasant, it fits with the Berserker’s “profile” if you will. When you hit him, he just becomes angrier, dishing the damage back to his attacker.
