Life Link

Life Link is the ability to connect one being's life to another.

History
The Tracer Demon sprinkled the Charmed Ones with an overdose of Dream Dust, their dream manifestations Chainsaw Killer, Ryder, and Slappy were brought to life. Phoebe injured her chainsaw killer in self-defense, but immediately suffered the same injury. When Leo Wyatt healed her, he was healed as well.

Kazi Demons and Swarm Demons were all connected to their respective kings. When the Charmed Ones vanquished the kings, they all followed.
