Charmed: Aura Choking

Aura Choking is the ability to choke beings with their own aura and suffocate them. The only known users are Grimlocks, who choke their victims by reaching out and then squeezing their hands. The victims then feel their aura tightening around their throat and they start to suffocate. Grimlocks seek out people with strong auras to kill them. In order to see these auras, they must steal the eyesight of children.
