Up to 25-40% Strength, as Stamina depletes.
7-10% Reload Speed for 2 seconds after Close Kill. Stacks 5 times.
14-20% Damage on Second, Third and Fourth shots in a Salvo.
Something different from the optimal hanging back and firing from cover with a boltgun. This build focuses sliding , dodging and dodge sliding to get up close with elites. Fast reload after elite kill means you have ammo in clip to keep shooting after. The Axe is for anything heavily armoured and to save ammo in less dangerous situations without loosing the dodge distance. Spade or knife would also be good here.
