Dread Scarecrow

You magically create the horrifying illusion of all your bones breaking and your body bending in impossible ways, accompanied by the sound of a shattered skull. All creatures of your choice in a 30-foot-radius sphere centered on you must succeed on a Wisdom saving throw or become frightened for the duration. While frightened by this spell, a creature's movement speed becomes 0 and it falls prone, its legs giving out under the fear. If an affected creature takes damage, it can repeat the saving throw at the end of its next turn, ending the effect on itself on a success.
