There's a script in the override folder named "j98_eud_player.nss", this scripts runs pretty much all the time, whenever you perform an action, or an action performed on you, it contains all the onheartbeat, ondisturbed, and other events. i used it to regenerate Chi and Focus on heartbeat, and to test some other stuff too. hope this helps..
