Binding Vow

Binding vows are considered by all Curse Sorcerer to be one of the essential tenets of cursed sorcery. Binding Vows are essentially contracts that an individual can make with one's self or another person. The act of abiding by the rules and restrictions agreed upon in these contracts can result in a greater power or the achievement of a goal, but breaking a binding vow has uncanny repercussions.

Vows with Oneself

Self-imposed restrictions that are potentially harmful to the creator, such as willingly limiting the amount of cursed energy they can use for a period of time, can increase the amount of the user's cursed energy and of their cursed techniques.
As a product of negative emotions, cursed energy responds to the desires of its individual user. As a result, the user can increase the power of their cursed energy by stating a self-imposed "cursed restriction" that creates riskier conditions to use their abilities. For example, by divulging one's cursed technique, it creates more risk for them, making their cursed energy swell in response to its user's resolve.
In addition, creating rules for using one's cursed energy and abiding by those rules which allow their cursed technique to improve in strength. The penalty of breaking a binding vow with oneself is the loss of whatever was gained through the contract.

Vows with Others

Contracts created between two or more individuals are bound by cursed energy. Both parties must agree to a particular set of conditions that benefit both parties. The penalty for breaking a binding vow with others is considered to be far greater than that of a self-imposed binding vow.
