Eyes of the Grave

As an action, you can open your awareness to magically detect undead. Until the end of your
next turn, you know the location of any undead
within 60 ft. of you that isn't behind total cover
and that isn't protected from divination magic.
This sense doesn't tell you anything about a
creature's capabilities or identity.
You can use this feature 4 times. You regain all expended uses when you finish a long rest.
