History of Lightning Grenade

The Lightning Grenade is an Arc grenade ability available to Titan, Hunter and Warlock Guardians. Its Arc subclass versions are the Striker (Titan), Arcstrider (Hunter) and Stormcaller (Warlock) variants. It sticks to any surface and emits bolts of lightning that damage anything moving through them.

The Striker Aspect Touch of Thunder gives the grenade a second charge and causes it to jolt targets hit by the initial blast.

Before Arc 3.0, the grenade's synergies included Aftershocks, where damaging enemies with Seismic Strike recharges it, and Magnitude, which grants an additional charge and extends grenade effect duration.
