Mana Contract
It is an agreement between two parties bound by mana itself.
To form a contract, both parties must willingly swear upon their mana. If either side goes back on their words or breaks the contract, they will lose the ability to wield mana altogether.
To be precise, since only those of [gold] rank or above can truly wield mana, a broken contract would cause their rank to fall back to [silver].
Although technically they could still use skills, they could never advance back to [gold] again. The door would close forever.
To form a Mana contract, at least one party must be [gold] or above. If the second party is a [silver] ranker and breaks the contract, they might not face immediate backlash, but they can never advance to [gold]. The ceiling of their potential would be sealed.
This is why very few people use mana contracts. No one can predict the future. It is unpredictable. A day may come when they have no choice but to break their word.
