+5-8 Bleed Stacks on Critical Hit.
+1-4 Bleed Stacks on non-Weak Spot Hits.
+30-60% Rending on Critical Hit.
+7-10% Reload Speed for 4 seconds after Close Kill. Stacks 5 times.
The idea is to be melee focused with bleed stacking and speed as your primary strenghts. Nade for easier horde clear and revolver for long range elite killing. This isnt entirely tested to perfection, but the overall build is capable of dealing with heresy easily so i'd assume it works for damnation.
