Wall of Wonder

You create an illusory wall in a point within range. The wall appears in any orientation you choose, as a horizontal or vertical barrier or at an angle. It can be free floating or resting on a solid surface. You can form it into a hemispherical dome or a sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-by-10-foot panels. Each panel must be contiguous with another panel. In any form, the wall's thickness can range from 1/4 inch to 1 foot. This wall can appear as any material, or it can be made to mimic the appearance of Wall of Fire, Wall of Ice, Wall of Sand, Wall of Stone, Wall of Thorns, or Wall of Water. No matter the form of this wall, the illusion includes audible, visual, tactile, and olfactory elements, but cannot deal damage. When you cast this spell, you can choose any number of creatures you can see. These creatures know this wall to be an illusion; it retains its properties to them, but they can freely pass through it. Otherwise, the elements of the illusion behave as if they were real. . A creature that uses its action to examine the wall can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, they also gain the ability to pass through the wall.

Creatures with truesight can see through the illusion entirely, treating it as a transparent image, also gaining the ability to pass through it.
