Tips and Details

• The stacks are displayed next to you as an ammo bar. Each stack will fill up one of the 5 slots.
• As the effect declines 1 stack at a time, the effective duration of 5 stacks is 75 seconds until you no longer have the buff at all.
• The buff duration starts going down as soon as your last Special Active's animation ends. For skills that can be extended, such as M-3 Flamethrower, it will start going down as soon as you release the skill button.

Trivia

• The skill is based on DFO's Female Launcher skill Heavy Firearm Mastery.
• For some reason, this passive's icon is similar to another skill of this path, Miracle Vision, likely due to both of them having an effect that increases All Skill Damage.
