Horrendous Fury (Recharge 6).
If creature is on an overlapping plane, and not on the same plane as the Windmill Monster, the Windmill Monster attempts to attack the creature from the Ethereal Plane with such fury, that the creature is dimension doored to a random location within 120 ft. There is no saving throw, as the laws of the plane have been warped by the Windmill Monster's fury.
