I think a good one for the hunter would be a double over shield with the added effect: changes all weapon damage to void damage (so all currently equipped weapons do void regardless of their original elemental damage). The more damage you take, the more damage you deal (up to 2x damage) until your over shield is gone. /// Or summon a shadow version of yourself that wields a hand cannon that does void damage. Lasts for 2 mins or until killed with no health regeneration.
