Veil of Sand

You conjure up a veil of heavy sand from the ground underneath you at a point you can see within range. You can make the wall up to 30 feet long, 10 feet high, and 10 feet wide, and it falls when the spell ends. Movement within the wall is slowed. A creature is blinded while in the wall’s space and must spend 3 feet of movement for every 1 foot it moves there. The area is covered with sand after the spell ends.
