Divine Sense

As an action:
You can open your awareness and know the location of any celestial, fiend, or undead within 60ft of you that is NOT behind total cover.
You know the type (celestial, fiend, or undead) but not its identity.
Within 60ft, you also detect the presence of any place or object that has been consecrated or desecrated, as with the Hallow spell.
