Necrotic Shroud. Your eyes briefly become pools of darkness, and flightless wings sprout from your back temporarily. Creatures other than your allies within 10 feet of you must succeed on a Charisma saving throw (DC 8 plus your Charisma modifier and Proficiency Bonus) or have the Frightened condition until the end of your next turn.
The way I am reading this is it happens when you use the bonus action, affects enemies within 10 feet when you take the bonus action and only lasts one round. It is not like an emanation that affects enemies at the end of their turn or when moved into it for the whole minute you are in form.
If so this is a pretty weak feature - small AOE, no range, lasts a round, usable only once a day.
