Binding Contract

Two people sign a contract in blood. There must be a powerful being to oversee the spell, whether it be a God, patron, or powerful spellcaster with access to 8th level spells. The spell lasts until the focus is destroyed or the one overseeing chooses. If a person goes against the terms they must make a wisdom saving throw and the other person is notified.

The spell can be upcast for two extra people for each level increase.
