5th Level Illusion
Casting Time: 1 action
Range: 120 feet
Components: V S M (A glowing crystal, carved into the shape of a plectrum)
Duration: Concentration, up to 10 minutes
A hypnotic wall of illusory magic springs into existence at a point you choose 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 is 1/4 inch thick. It lasts for the duration.
When the all appears , each creature within its area must make a Wisdom saving throw. On a failed save, a creature is charmed for 1 minute. A creature charmed by this spell is incapacitated and has a speed of 0. Those who pass their saving throw have their movement speed reduced by half until the start of their next turn.
Creatures that choose to try and pass through the wall or start their turn inside the area of the Wonder Wall must make a Wisdom saving throw, becoming charmed as above. The charm effect ends on a creature if it takes any damage or if anyone else uses an action to shake the creature out of its stupor. A creature woken from this charm effect cannot be charmed by the same spell for 24 hours.
