Until the end of her next turn, she can know the location of any undead within 60 feet of her that isn’t behind total cover and that isn’t protected from divination magic. This sense doesn’t tell her anything about a creature’s capabilities or identity.

Radiant Soul. Zysca can use her bonus action to unleash the divine energy within herrself, causing her eyes to glimmer and two luminous, incorporeal wings to sprout from her back.

• her transformation lasts for 1 minute or until she ends it as a bonus action. During it, she has a flying speed of 30 feet, and once on each of her turns, she can deal extra radiant damage to each target when she deals damage to it with an attack or a spell. The extra radiant damage is 20.
