Originally created by a secret society of death-worshipers to carry out their ritualistic executions, use of this monster is considered rather tasteless in modern times. Through its psychically active gaze, it "locks on" to a living being and slowly drains its vitality until it dies, a process that can continue to function across great distances. It ticks like a clock as its victim withers, and chimes like a "cuckoo" clock when the prey finally dies.
