Armet du Dieu Unique

If it is not behind total cover you know whether
there is a celestial or fiend within 30 feet of you,
as well as where the creature is located.
After a long rest, you can pray to one of the entity listed on the Helm of the Gods table to store the
listed spell, replacing any spell that is already
stored there. The save DC for the spell is 13.
The helm has 3 charges. To cast a spell from the
helm, you must expend 1 charge, and the helm
regains 1d3 charges daily at dawn.
