The Yamanaka's secret mind techniques: the spirit cast out of the body to take another's, or to throw their mind into disorder.
Your spirit shoots out in a straight line; if it strikes someone, you become them for 30 seconds: you're in their body, walking, fighting and talking as them, while your own body stands empty where you left it (struck, it calls your mind home). Right click again to return early.
Throw the mind of whoever you look at into disorder for 15 seconds: a player's controls are turned around (forward is back, left is right); a creature turns on whoever is nearest it and attacks them. Right click to cast.
