Target receives 1-4 Stack(s) of 10% Damage if already Staggered. Lasts 5s.
1-4% to Instakill human-sized enemies on Chained Heavy Hit. Stacks 5 times. Note that other potential triggers will not be activated on Instakill.

5-8% Strength for every shot fired during continuous fire. Stacks 5 times.
This kickback build is largely centered around using your kickback to delete large groups of elites, especially melee elites. The rending bonus from Hail of Fire and Dominate can allow a kickback to deal up to 50% of its regular damage to an ogryn crusher, so you can easily two tap ogryn crushers with this build. Brownie points if you play with an ammo regen vet.
Also, if your ult is on cooldown and you're facing multiple human-sized enemies, pull out your bully club and get to work. It's not stated on the blessing, but Haymaker builds stacks multiple times for a single attack, and the stacks dissipate one at a time. Also, you can use light attacks with the bully club and not lose stacks of haymaker while attacking. Furthermore, the MK3b brunt's basher is the best bully club to use this blessing as all of its heavy attacks are sweep attacks, so you can hit say 5 enemies in a single swing, and each enemy has an x% chance of dying instantly. This makes it useful when dealing with packa of ragers. Not to mention, this blessing is useful for taking out a charging mutie at times. Skullcrusher is also a good general damage blessing as it works with light and heavy attacks, and your teammates can benefit from Skullcrusher stacks, too.
For curios, i like using health curios since an ogryn with this build has a large amount of toughness already. Moreover, sniper and gunner damage resistance are always good choices to take. The other slots are up to your personal preference.
