Aruther's Everlasting Bond

When someone passes on from this world, their soul leaves an imprint in this world. An experienced arcanist can bind this imprint to an object that was sentimental to them during life. During the ritual, the caster touches the object which the imprint of soul will get bound to. Over the course of casting the spell, the imprint is inscribed on the object.

Once the imprint is inscribed on the object it becomes a magic item. The imprint resides on the ethereal plane and, as a Magic action, the holder of the object can reveal the soul to everyone or just themselves. You can dismiss the imprint back to the ethereal plane at any time, no action required. Even if the imprint is not revealed in this way they can always talk to the creature that has the bound object, but can only talk to other creatures if they are revealed to them. The imprint cannot move more than 30 feet from the object and can only perceive whatever is within 60 ft. of the object. Their knowledge, personality, and overall nature is exactly the same as when they died, but they can change over time through conversation and perception. These changes are not permanent and only last while the imprint in bound to the object. The imprint is friendly to all creatures, but if they recognize a creature from their life they treat them as such.

This spell can only effect the same imprint once. To cast this spell on the same imprint again, the previous object must be destroyed or dispelled. The object has 50 hit points, an AC of 18, and is immune to all forms of damage except Force. After the imprint is inscribed on the object it will stay there until the object is destroyed.
