A wall of sand that is 5 feet tall, 5 feet wide, and 1 foot thick materializes from the ground up in an unoccupied space that you can see within range. The sand functions as solid stone while in its wall form. The wall has AC 13 and 10 hit points. Reducing the wall to 0 hit points destroys it and might cause connected walls to collapse at the GM’s discretion. You can end the spell early by using an action to dismiss it. When the spell ends, the wall crumbles back into sand.   If you cast the spell as a ritual, the wall lasts until it is destroyed or dismissed.
