Deadly Efficiency is a mod that increases the damage of an Arch-gun while aiming for a brief time upon reloading from an empty magazine.
- Stacks additively with other base damage bonuses such as Rubedo-Lined Barrel.
- This mod has a buff icon which appears next to the player's health and shield display to indicate it is in effect.
- Currently, in space combat this mod does not function at all, likely due to arch-guns "recharging" in space instead of reloading as they do in atmospheric combat.
