Resonant Image

You create a distortion in the air through the vibration of particles. You create an image with whatever appearance you desire, occupying 10 cubic feet at a point of your choice within range of the spell. This image moves at the end of each of your turns for the duration of the spell to a point of your choice within range. This image ignores cover and can pass through objects normally, dealing damage to them.

If a creature occupies the same space as this image when the spell is cast, moves through the space occupied by the image, or starts its turn there, the creature must make a Constitution saving throw. On a failure, it takes 9d8 disruptive damage and becomes Paralyzed for the duration of the spell, repeating the saving throw at the start of each of its turns to end the condition.

If a creature fails this saving throw a number of times equal to its Constitution modifier (minimum of 2), the creature falls Unconscious and can’t be woken until the spell ends.
