Why ' d I get down voted to hell ? <| sep |> Sorry I wasn ' t clear , you can spec for critical chance on things like Mask which previously wasn ' t advised because you don ' t have to worry about survivability . This build is VERY tanky , you can minroll stamina because Skillpower inadvertently gives you bonus resistances . Ballistic Shield gives you Damage Resistance this is a hidden bonus which scales with skill power . Booster shot gives you 15 % damage resistance or 10 seconds which is another hidden bonus . Combine this with ~ 60 % damage mitigation from armourmods and Boostershot constantly off cooldown you are a walking juggernaut . Edit here are the hidden bonuses sorry potato quality , can ' t take screen shot because in a server queue .
