Blood Contract

You magically bind a contract written in the blood of all entities involved in its terms. Every item in the contract must be precisely written. If a term can be interpreted multiple ways, then the Blood Contract will apply to all of the ways a term may be interpreted by the DM.

If a term or a rule defined in the contract is broken by an entity whose blood is bound and no failure condition is defined explicitly, the entity must make a Wisdom saving throw once per day while the rule remains broken. On a failure, that entity takes 5d10 psychic damage, or half that damage otherwise.

You can end the spell early by spending 1 hour to dismiss it. A remove curse, greater restoration, or wish spell also ends it.

At Higher Levels. When you cast this spell using a spell slot of 5th it can only be removed by a greater restoration, or wish. When you cast this spell using a spell slot of 9th level it can only be removed by a wish.
