You create a shallow set of shifting extradimensional holes in the ground in one 5-foot square. Any creature within that square or entering it later must make a Dexterity saving throw, falling prone and taking 1d6 bludgeoning damage on a failure. A Medium or smaller creature that succeeds on its save does not fall but is knocked off balance, having its movement reduced by 10 feet and taking a -1 penalty on attack rolls and ability checks until the end of its next turn.
