Feed the Void

Feed the Void is a Voidwalker aspect from the Attunement of Hunger tree that takes two fragment slots. A Void kill triggers Devour, a healing buff that also restores grenade energy. Earlier versions of the aspect worked differently (it was once an active ability and later became a Void and then a Prismatic aspect), so check current patch notes for exact grenade-consumption behaviour.

Common pairings include Child of the Old Gods and, with Contraverse Hold, Chaos Accelerant in place of Child of the Old Gods, which lets Feed the Void be used while charging a Void grenade. In PvP, Empowering Rift works well alongside it.

Void Leech builds commonly use Echo of Remnants, Echo of Undermining, Echo of Persistence and Echo of Expulsion. Void Caster builds commonly use Echo of Instability, Echo of Undermining, Echo of Vigilance and Echo of Harvest. Guides are dated, and some rate other fragments higher.
