A compass with two sides. One side looks like a regular compass and functions like one in the real world. The other side of the compass has a dial resembling the night sky, with the needle shimmering in various shades of purple. This side functions only in the spiritual world and indicates the nearest passages to the real world.
Any spirit that hears the bell within 30 feet must make a Wisdom saving throw. If the spirit fails the saving throw, it is banished for 1 minute or until it takes damage.
