Impromptu Ammunition

Overview

Impromptu Ammunition speeds up ammo gain: final blows increase ammo meter progress from all sources for a short time. It is useful on weapons that rely on special or heavy ammo, because kills fill those meters faster for the duration. It originated in Season 27.

It rolls on a range of weapons, including Sidearms, Machine Guns and Rocket Launchers, so the trait is a common pick for heavy-ammo builds.
