The Kanohi Vexon is the Mask of Cursing. It allows its user to mutate other sapient beings within their range of vision into Rahi-like creatures permanently. The length of the process varies, depending on the mass of the target. If active for a short time, it only causes disorientation. The mutations are derived from the target's morals, ethics and affinities. The mask can revert past mutations. The target retains its identity and intelligence after being mutated.
