Bullets! Seriously. I've had good luck with:eyesluna, gaheris, imago loop, finalas peril, haakons hatchet, arminius, shadow price, paleocontact, hand of judgement, treads upon stars, sateriene rapier, nl shadow, pdx45, villiany, nirwens. That's just legendary primaries since Tuesday. Got a vault to run through this weekend :)
