Trans-Dimensional Pocket

You create a small, unstable pocket of non-Euclidean space. Choose an area of space within range, up to a 10-foot cube. Any creature or object entering this space must make a Wisdom saving throw. On a failed save, they are briefly shunted into an adjacent dimension. At the start of their next turn, they appear in a random, unoccupied space within 20 feet of the pocket. On a successful save, they are disoriented, and their speed is halved until the end of their next turn.
