Exotic Helmet
"To survive out here, you need eyes in the back of your head." —Lord Felwinter
Warlord's End
Powered melee hits weaken targets. Powered melee final blows create a burst of energy that weakens nearby targets. Finishers and final blows against more powerful targets increase the radius of the burst and the length of the weakening effect.
