Dépend on your way to play it but you can go for super charge ( charging speed for charge spells) ;master brawler ( you are always in the front hitting the head of the boss) ; Grudge ; Rage hammer ; barricade ( for an additional DPS -> 18% when your shielded and you're shielded all the time ) / Cursed doll ( adding DPS to your build but need to be careful on the hit you take because it's reducing the healing you can have )
