A psionic scythe is a type of psionic blade utilized by protoss Avengers. They are very similar to the shadow scythes of the Nerazim, as Khalai stranded on Aiur attempted to emulate the ways of the dark templar in order to attempt to take back their homeland. Like the warp scythe, the psionic scythe has two psionic edges on opposite sides of a pole.
