Contract Familiar

Sign a familiar contract with a willing creature.

The creature keeps its type but gains familiar's traits.

Once signed, it cannot be undone unless the familiar's soul is destroyed.

The creature's soul is bound to the caster. When a creature's physical form dies or is destroyed, the caster can use a total count of 6 spell slots of any level to perform a ritual to recreate its body and put its soul back into it.

You can sign a contract with Tiny size creatures.

When you cast this spell slot of 5th or higher, the size of the contracted creature increases by 1.
