As in Xanathar's Guide to Everything with the following added:

When the wall appears, each creature within its area must make a Strength saving throw. A creature takes 4d6 bludgeoning damage on a failed save, or half as much damage on a successful one. 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, you may increase its length or height by 10 feet and its damage by 1d6 for each slot level above 3rd.
