You liquefy ground made of stone, earth, or sand in a 30-foot radius centered on a point within range. The material dissolves into a pit of quicksand 30 feet deep, transforming the surface into difficult terrain. A creature or object that can’t support itself over the quicksand (such as with a foundation outside the affected area or clinging to a rope) begins to sink.   Each creature and object that starts its turn in the quicksand or enters it for the first time on a turn must make a Strength saving throw. On a failed save, a target is restrained.   A creature or object restrained by this spell must make another Strength saving throw at the end of each of its turns. If a target succeeds on three of these saves, it is no longer restrained. If it fails three of these saves, it sinks beneath the surface for the duration.   A sunken creature is restrained and blinded, has total cover against all attacks and other effects, and begins suffocating. In addition, it takes 6d6 bludgeoning damage at the start of each of its turns until it is freed.   A creature outside the spell’s area can use the Help action on a creature restrained by the sand, granting it advantage on the next Strength saving throw it makes against this spell.   When the spell ends, the quicksand resolidifies, returning to its original state and shunting all creatures and objects
