History of Explosive Light

Explosive Light is a weapon trait found on Rocket Launcher and Grenade Launcher weapons. Picking up an Orb of Power grants a stack (max 6); each shot consumes one, giving increased blast radius and damage (about +60% explosive damage on Grenade Launchers, +25% on Rocket Launchers) and projectile velocity. The enhanced version raises the cap to 7 stacks.

Sources disagree on its debut: the Destiny 2 Wiki says Season 16, while light.gg-indexed pages say Season 15.
