History of Reservoir Burst

Reservoir Burst is a Legendary Trait weapon perk, introduced in Season 4, that rolls on Fusion Rifles. When the battery (magazine) is full, your next burst deals additional damage and enemies explode when they die. It rewards keeping the magazine full and adds crowd control on kills, which makes it a core perk for ammo-efficient builds. It rolls on a wide range of fusion rifles, including Afterlight.
