17-20% Movement Speed for 2s on Weapon Special Activation.
11-14 Bleed Stacks from Special Attacks.
You can Hipfire with this weapon while Sprinting. 6-15% Close Damage while Sprinting. Also reduces weapon spread at all times by 30%.
10% Critical Chance for every 0.3-0.45 second while aiming. Stacks 10 times. Discharges all stacks upon firing.
For when you want to pop heads but don't want to play a Psyker. You can keep up Executioner Stance through reloads by only reloading one bullet and popping another head, then reloading again. Lather, rinse, repeat. And with regen, you'll always have a couple Krak Grenades ready for the biggest targets.
Melee weapon can be by preference. Anything you're comfortable using against hordes. I go with the bleeding chainsword because it can help chip down Monstrosities without needing weak-spot hits.
If you have trouble keeping up 10 stacks of Marksman's Focus for the Chink in Their Armor bonus, go ahead and drop it for something else as you like. I recommend Field Improvisation or Grenade Tinkerer.
