Aspect of Elbegdorj

You conjure up 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. Any ranged weapon attack that passes through some or all of the wall’s space has disadvantage on the attack roll.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the maximum length and height of the wall increase by 30ft for every slot level above 4th.
