Roake's Clay Urn

As an action, you can present this clay urn and speak a handful of ritualistic phrases unique to it. One spirit of your choice that can see or hear you within 30 feet of you must make a DC 13 Wisdom saving throw. On a failed save, it is pulled inside the clay urn and sealed away. If the spirit has a challenge rating of 3 or higher, it automatically succeeds on the save. While the spirit is sealed inside, it is in a state of slumber. It doesn't need to eat or breathe, it doesn't suffer from any wounds or illnesses, and it ceases to age. The creature is released when the urn's seal is broken or the urn is destroyed. At which point, the creature reappears in the nearest unoccupied space to the urn, waking up as if no time had passed. Once Roake's Clay Urn has been used to seal a spirit, it can't be used again.
