When one of your opponent's units uses a Force-activated ability that costs 4 or less Force, disrupt that ability if you have a Jedi in any arena. Your opponent loses 1 Force. You may also tap that unit and 2 of your Jedi in any arena. If you do, until end of game, you may choose not to untap those Jedi. As long as those Jedi remain tapped, that unit can't untap.
