Riven mod can be replaced with anything you see fit, a bane mod, damage or anything you prefer. Damzav Vati should be maxed in a full build. This works very well with builds that utilize eclipse or xatas whisper, xatas whisper makes all 41 projectiles hit where it proc's so assuming you hit the head it will probably kill anything(outside of demolyst) in 1 magazine, if not, your better off just using melee. Effectively, build up your galvanized mods and arcane then just kill everything, exilus is also optional it just helps you hit the enemy with more pellets.
