wall of soap

You enlarge a bar of fine soap to be 20 feet tall on a solid surface within range. You can form it into a hemispherical dome or a sphere with a radius of up to 20 feet, or you can shape a flat surface made up of twenty 10-foot-square panels. Each panel must be contiguous with another panel. In any form, the wall is 3 feet thick.

If the wall cuts through a creature's space when it appears, the creature within its area is pushed to one side of the wall and must make a Dexterity saving throw. On a failed save, the creature takes 5d6 bludgeoning damage, or half as much damage on a successful save.

The wall is an object that can be damaged and thus breached. It has AC 10 and 60 hit points per 5-foot section, and it is vulnerable to necrotic damage. Reducing a 10-foot section of wall to 0 hit points destroys it and leaves behind a sheet of foamy soap in the space the wall occupied. A creature moving through the sheet of foamy soap on a turn must make a  saving throw. That creature takes 2d12 radiant damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage the wall deals when it appears increases by 2d6, and the damage from passing through the sheet of water increases by 1d12, for each slot level above 4th.
