Divine Sense

As an action, until the end of your next turn, you
know the location of any celestial, fiend, or undead within 60 feet of you that is not behind total cover.
You know the type of any being whose presence
you sense, but not its identity. Within the same radius, you also detect the presence of any place or object that has been consecrated or desecrated.
You can use this feature a number of times equal
to 1 + your Charisma modifier. When you finish a
long rest, you regain all expended uses.
