Swan Song

Aria never managed to get anyone with Swan Song. After 20 seconds of humming, people usually just hit her with a sword.

You hum a haunting melody that can compel creatures who can hear you within range to die. If you maintain concentration on this spell for 30 consecutive seconds, creatures within 60 ft of you that have 100 hit points or fewer and can hear you, die. Otherwise, the spell does not affect them.

If you use verbal components to cast a spell while concentrating on this spell, this spell ends.
