The Kanohi Avsa was the Mask of Hunger. It gave its user the power to drain light, physical energy, or positive emotions from a single target over a distance. Physical energy stolen by the user will increase the user's physical abilities. Avsa can be used to make completely lightless beings by draining all of a target's light and then placing a "mind barrier" in the target. However, a Klakk can break this barrier, allowing light to return.
