This build is designed to deal massive damage with your fists while tanking a good amount of damage. It's meant for someone who has The Armory and The Underdome. For a class mod, bonuses to Endless Rage and Short Fuse are most important, preferable +3 or +4 in both. A mod that gives bonuses to Iron Fist, Heavy Handed, and Sting Like a Bee is also nice. The strategy is to punch as much as you can while berserk is up, then, in its short downtime, shoot the enemy with your most powerful gun, like a Maliwan Hellfire
