10-25% Rending vs Staggered Enemies.
Target receives 1-4 Stack(s) of 10% Damage if already Staggered. Lasts 5s.
4.5-6% Critical Chance for each expended round in your weapon (resets on reload).
7-10% Reload Speed for 4 seconds after Close Kill. Stacks 5 times.
An all-rounder build that allows you to carry damnation to auric maelstrom damnation.
The revolver, used sparingly, will allow you to eliminate specials efficiently without having to rely on your team or without being overly ammo hungry.
The rest of the build is focused on getting into the thick of things and doing massive amounts of crit/headshot damage. Duelist, Blazing Piety, and Faithful frenzy, combined with the shock maul's heavy - light combo chain will shred hordes, while Benediction and Enduring Faith provide superb damage reduction. While you will not mince hordes as well as other melee weapons, shock maul retains excellent defensive capabilities (similar to VT2 one-handed mace). This build then makes great use of stun grenades to ensure res's.
If you die with this build, it is 99.9% your fault (as opposed to being limited by the class/build; eg you're a psyker alone in a mixed horde, or an ogryn fighting against 50 gunners), as this gives you all the tools you need to clutch in nearly any situation. By no means a guaranteed win build, but you will not be held back by this build. You have enough stagger, DPS, and maneuverability to always fight your way through.
