Cry of the Banshee

You release a vile shrieking sound directly into the minds of your foes. Choose any number of targets within range; these targets hear this shriek, even if it is deafened or can normally not hear sound, and become marked for death. At the start of a marked target’s turn, the target must make a wisdom saving throw against your Spell Save DC. If the target succeeds on three of these saves, it is no longer marked. If the target fails three of these saves, it instantly drops to 0 hit points.
