Shadow Manipulation

Shadow Asphyxiation is the ability to generate a smoke-like darkness and force it to obstruct the air pathways of other beings. This was the main mode of murder for the Woogyman prior to his vanquish in season seven. The Woogyman appeared to be immune to the Charmed One's active powers which allowed him to get in close enough to choke them; however, the method of killing was never portrayed as successful in Charmed.
