Everlasting Oath

When you set the terms and conditions for a deal you make, you can cast this spell to make sure neither of you can break this deal. After this spell is cast, you are physically unable to go against the terms you have set. For example, you set the conditions for a duel, if you lose you have to stop learning magic, if you win, your opponent has to apologize. The spell can be canceled by casting again, and canceling the spell does not take up a spell slot. Only the caster can cancel this spell and both parties involved must be in agreement to cast or cancel the spell.
