This capturing effect last until you deal damage to your opponent or this action is cancelled. Then place all the die that was captured back into your opponent's field. This effect is not considered targeting.
When used, at the start of your attack step, target an opposing character die with a lower level than one of your dice. You must attack with it, it provides you with it's ability. If the controlled die is unblocked or knocked out, it goes to your opponent's prep area at the end of your turn. If the die is blocked but not knocked out, it goes back to your opponent's field. On the burst side, you can target any opposing character with equal or lower level than one of your dice instead. If you have only level 1 character dice in your field, unless you rolled a double burst side for this action, you cannot target any opposing character as none of them are lower level.
