Wail of the Banshee

Upon casting this spell, a ghostly visage forms in a point within range and wails supernaturally. All creatures must make a constitution saving throw or fall comatose, with the exception of creatures that can't be charmed. In the beginning of an affected creature turn it must save again, if it succeds the creature awakens, otherwise it remains comatose and receives 4d10 psychic damage which won't wake it. Any other source of damage will wake a creature that suffers the effects of this spell and a creature can use it's action to wake a creature.
