The Kanohi Avsa, the Mask of Hunger, was capable of draining energy or light from a target over distance.1
Notes
Vamprah used his Kanohi Avsa, the Mask of Hunger, to feed on the hopes and dreams of his victims.2
It was not one-of-a-kind.3
If an Avsa wearer were interrupted while attempting to drain the light out of someone, the effects be the same as a half-drained being like Takanuva.4
