Target receives 1-4 Stack(s) of 10% Damage if already Staggered. Lasts 5s.
Hitting an enemy gives them 1-4 stacks of 2.5% Brittleness. Debuff lasts for 5 seconds and can have a maximum of 16 stacks.
5-8% Strength for every shot fired during continuous fire. Stacks 5 times.
You can Hipfire with this weapon while Sprinting. 6-15% Close Damage while Sprinting. Also reduces weapon spread at all times by 30%.
Can Perma CC Bosses with heavy + slap combo, including the Beast (but Weakspot is hard to hit). Plague Ogryn requires 2 heavy weakspots > slap. Daemonhost you need to aim the slap above their head for it to connect. Can start the combo with a charge to get into pole position.
One shot Mutants with full bore and run 'n' gun from medium range.
If you have your melee out, your bleeds apply thunderous, giving your team 40% brittleness.
Other Specials die in <10m in 1 shot from kickback or they get staggered from further.
Mixed hoard stands no chance to heavy spam. Or Heavy 1 > Light 2 if you're feeling spicy.
Your charge applies thunderous and skullcrusher (Tho it doesn't apply soften them up for some reason), and at the end of your charge you reapply another "burst" of stagger in a small area around you, so make sure you charge towards key targets and use S, RMB or even jump to stop the charge. Applying double stacks of bleed, brittleness and damage will kill Dreg Gunners. Obviously you can quicken their death with some smacks.
Main threat is spaced out gunners, and really far away snipers (will have to box if no one else can get it). You can 2 shot snipers from 50m but it needs surgical stacks.
A megastack of crushers is also somewhat hard to control, either charge into them followed by 1 Heavy > Punch for each, give them the box if they're on your friends and for some reason charge is on cd. Circle Strafing them and dodging while heavying + slapping should stagger them enough so they don't do their overhead.
