Initiation Time: 1 action
Range: 60 feet
Duration: Concentration, up to 1 minute
Sand floods a 20-foot square starting from a point within range and then softens, catching hold of all creatures touching the ground. For the duration, the ground in the area is difficult terrain.
A creature in the area when you initiate the form must succeed on a Strength saving throw or be grappled by the sand until the form ends. A creature restrained by the sand can use its action to make a Strength check against your ki save DC. On a success, it frees itself.
At Higher Levels. When you initiate this form at a higher level, the range and the radius of the square increase by 20 feet for each level above 1st.
