From Destinypedia, the Destiny wiki
- "A grenade that sticks to any surface and emits bolts of lightning."
- — In-game description
Lightning Grenades are a type of Arc Grenade Ability. Lightning grenades are an emitter that flies through the air and sticks to surfaces, but not creatures or temporary barriers. The grenade then unleashes highly damaging lightning bolts from its tip, damaging anything that moves through them.
- The Touch of Thunder Striker Aspect grants a second grenade charge and causes the grenade to jolt targets hit by the initial blast.
