I see... I always figured the contracts work by magic, which can be powerful as the individual who is using it and his/hers ammount/pool of energy. Basically magic and energy are different things, yet connected to each other. By concentrating a set ammount of your energy into a specific action, you either trow a Ki blast, fly, cast a spell and stuff, the ammount of energy focused into an action, determines how strong said action will be. Therefore, a contract by a Demon could be broken by a being of superior power and any attack by a weaker opponent would be virtually useless against a stronger opponent (unless is caught off guard, or already drained from battling someone else...) At least that's how I assumed things work in MGE world.
