- "A grenade that attaches to any surface and emits a torrent of damaging Void Light."
- — In-game description
Void Spikes are a type of Void Grenade Ability. The Spike is an emitter that flies through the air and sticks to any surface, but not creatures or temporary barriers. The emitter then unleashes a long spike of Void energy that deals continuous high damage. The emitter can be destroyed by enemy fire and melee attacks, ending the grenade prematurely.
