Wall of Sand

3rd-Level Evocation
Casting Time: 1 action
Range: 90 feet
Components: VSM (a handful of sand)
Duration: (C) 10 minutes

You create a wall of swirling sand on the ground at a point you can see within range. You can make the wall up to 30 feet long, 10 feet high, and 10 feet thick, and it vanishes when the spell ends. It blocks line of sight but not movement. A creature is blinded while in the wall's space and must spend 3 feet of movement for every 1 foot it moves there.

When the wall appears, each creature within its area must make a Strength saving throw. A creature takes 2d10 slashing damage on a failed save, or half as much damage on a successful one. Creatures who fail this save are blinded until the end of their next turn. A creature must repeat this save when it enters the wall for the first time on a turn or ends its turn there

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10, and you may increase its length, height, or thickness by 10 feet for each slot level above 3rd.
