Essence of theBinding Vow

You receive the ability to impose contracts and limitations in exchange for blessings and powers of the same magnitude.

This power is fiat-based, and not subject to lesser form of systems, including skill, magic or superpowers. It works conceptually, and thus you don't need to have the skill or ability to actually realize the effect like in HunterXHunter of Jujutsu Kaisen.

Vows with oneself allows the sacrifice ,exchange and binding of power, a set of actions, risk or any other factor of your will. You may simply bind one portion of your power to enhance other, exchange it with another power, or tweak the power to your specifications.

This form of binding may be unmade at will, in which case gain and losses are harmlessly equalized.

Examples include but are not limited to: Exchange a time loop power into a resurrection one, a quicker power up for loss of potential, greater potential for present power; including hand seals, time and chanting to enhance a spell. Sacrificing all your mystical energy to empower your body and vice versa, make money or lifespan disappear to become skilled at something.

If you choose to exchange power for potential and later unbind that vow, you will keep the gained power.

You may also give and break such restrictions on others, as long as they are willing and ready to bear the price of such. Break Maki's Heavenly Restriction and turn her back into a normal sorcerer, help other sorcerers into possessing powerful curse-less bodies. Give Superman powerful magical or psychic abilities by weakening his physical body.

You may tweak the binding to allow for breaking or switching off and on. By default, it's unbreakable for anybody but you.

You may form vows between two parties. They must decide on the set of conditions, benefits and restrictions beforehand and agree to it. You may decide what happens if someone breaks this vow. It can be anything to instant death, cursed luck, sickness, or anything else you desire.
