6.5-8% Strength for 3.5s on Hit. Stacks 5 times.
Hitting at least 3 enemies with an attack, increases your damage by 24-36% for 3 seconds.
5-6.5% Strength for 3.5s on Close Range Kill.
4.5-6% Close Range damage on Repeated Hit. Stacks 5 times.
All 3 marks of the Heavy Sword work fine so personal preferance is fine generally i reccomend MKIX.
Most weapons will work in this build but i would reccomend sticking to something focused on Ranged Special killing.
You can swap your [Main Stat] Max Health for 1 additional Wound(s) for a little safety if you are not fully confident you wont down.Other notable options if desperate are Damage Resistance (Snipers) so they dont chunk your health if they hit you, Damage Resistance (Bombers) to allow you to pass through gas clouds with less corruption & Revive Speed (Ally) to speed up saving your team.
You can take points from Serrated Blade for Get Back In There! if you want more survivability.You can freely throw your Krak Grenade at Crushers, Bulwarks & Bosses as you have 2 forms of regen.
