Cry of Dystopia

With the dark and powerful forces of Rock and Metal flowing through you, let loose a ballad of complete destructive energy upon your foes. Target creatures that can hear you with a sphere. This fills corners. Those creatures fall prone take 4d8 necrotic and 4d8 force damage and are unable to move or get up for the duration of the spell. Any creature that moves into the sphere must make a constitution saving throw equal to or higher than your CHA score + proficiency.
