This day I want to share my build to you. The rules of using this build is simple, you cast Vault to engage and disengage, use Scalp as enemy goes near then quickly use Shotgun (Scattershot). Then quickly run away for this is a low survivality build. It is not perfect for the moment though, so feel free to improve this build like brutal for more damage on deadly. If I remember, I reached 300k - 400k damage I think. I don't think this build can defeat Immortal builds btw.
