7.5-15% Weak Spot Damage. Weakspot Kills also ignore Enemy Hit Mass.
6.5-8% Strength for 3.5s on Hit. Stacks 5 times.
4.25-5% Strength for every Enemy you Stagger. Stacks 5 times.
Ranged hits add 1-4 stacks of bleed to enemies.
The best gun for Executioner Stance.
Usually, I'd go for Get Back in the Fight, but with Executioner Stance, you don't gain any toughness regen from your ultimate, and thus, any extra toughness is nice.
Kill Zone and Opening Salvo are pretty interchangeable. Kill Zone helps a bit more for clearing rooms of gunners, whereas Opening Salvo is universally applicable but very RNG-dependent, considering you only have 5% base crit chance.
Close Order Drill and Confirmed Kill are flex points. As previously mentioned, any extra toughness regen and tankiness are nice when your ultimate doesn't give you toughness. However, Volley Adapt does make the gunplay with the Bolter much smoother.
