7.5-15% Weak Spot Damage. Weakspot Kills also ignore Enemy Hit Mass.
Target receives 1-4 Stack(s) of 10% Damage if already Staggered. Lasts 5s.
Just as an FYI this build is designed around the needs of 4gryn melee only. I'd recommend a shield or pickaxe as your weapon with this build into any normal havoc game. Power Maul is annoying to use and has absolutely abysmal damage output. Most mixed squads probably do not need the advanced aoe stagger. But 4ogryn needed a way to slow things down.
