Mitre of the Hierophant

Wondrous item, rare (requires attunement by a cleric or paladin)

This ostentatious hat channels the wisdom of the divine into its faithful servants. The wearer has advantage on Intelligence (Religion) checks and on Charisma (Persuasion) checks with creatures of the same faith or alignment. If the wearer casts augury, commune, divination, or a similar spell more than once per day, the chance of a random result 6 is reduced by 25%. In addition, you can concentrate for 1 minute to ask a single question of your deity (as if you had cast commune, though this does not increase the chance of a random answer). After asking this question, you cannot use this ability again for 1d3 days.
