Black Sails of Schnai

Enchanted in the land of Snow Barbarians and blessed by their shamans, these square sails are hoisted only on the funeral ships of great heroes and lords. The deceased's body is burned along with the ship and all but a small piece of the sail, that contains the spirit of the deceased. While you hold this piece of sail, as a Magic Action you can conjure a Medium spirit to a point that you can see within 30 feet of you. that you can see within 10 feet of you. The spirit lasts for 1 minute or earlier if you dismiss it as a Bonus Action. When you are within 30 feet of the spirit, you deal 2d12 additional psychic damage on any successful weapon attack. As a Bonus Action on your later turns, you can teleport the spirit to an unoccupied space that you can see within 30 feet of you. Once you use this property, you can't use it again until you finish a Long Rest.
