Chaos Warp

You conjure warped physics from another plane in a 30 ft cube centerd on an area of your choice. Every creature that has moved since its last turn may be teleported to a new location within a 50 ft cube of the center of the cast area, it's new position is chosen by the DM and should be in favor of the caster by default. Each creature teleported must succeed a wisdom saving throw or it becomes surprised.

If you cast the spell two or more times before finishing your next long rest, there is a cumulative 25 percent chance for each casting after the first that you get unfavorable new positions. The GM makes this roll in secret.
