As I turned the corner he was locked in stone; as the set bonus allows. He would have died to the NPCs and lost minimal Tel Vars, but instead it brought him back to life so I could land the killing blow and take the majority.

A ganker cannot take his target out from the middle of a group and run before anyone can react, because he has to wait until the proc ends to finish off his target. Useless solo, great for a zerger.
