You blow on a whistle, releasing an inaudible sound. Choose a point on the ground within range. The first time a creature moves 5 feet or more while within a 10-foot Square centered on that point before the spell ends, an eldritch maw immediately erupts from beneath the ground, dealing 2d10 Piercing damage to each creature within the Square and knocking one of them Prone (decide when the spell triggers). The spell then ends.
