Ghost Stance is a special stance you earn by winning the duel against General Temuge in The Ghost of Yarikawa. Charge it, trigger it, and cut down up to three enemies who can't fight back.
Any enemy hit resets the kill counter; fire and fall damage don't. When active, the screen goes grey, enemies stop attacking and each strike kills.
The Charm of Ghostly Fury makes hits only take one off the counter and adds a fourth kill.
