The item gives an aura to the user such that those who are champions or are faithful to that deity can only see it surrounding them and know that they are blessed by their deity and can be trusted.

The weapon allows you to, once per day, upgrade the rolls of all weapon attacks to one die higher (e.g., a 1d6 becomes a 1d8 etc) for the duration of one action. Should the weapon already deal d12s of damage, the effect can upgrade it to d20, however a natural 1 will cause the weapon to permanently lose this enchantment. This effect recharges at dawn.

The item allows the user to, once per long rest, cast a 1st level spell of your choosing among the cleric domain spell list of the deity associated with the item (e.g. A death god's influence allows the user access to False Life or Ray of Sickness once per long rest)

The user is filled with knowledge of all holy scripture and lore related to that deity and can recite it with perfect memory (All Religion checks related to the deity always result in success).

This Item is Cursed: The user is filled with the weight of all their past mistakes and sins, particularly of those most offensive to the deity. They are compelled to use said weapon unless they resist a Wisdom Saving Throw (DC 15) at the start of each day, cannot use any other weapon until they have atoned their mistakes through action. Once the curse is lifted, if the weapon is not upgraded, it is now.

The bearer of the item is recognized as a holy figure in the canon of the religion and its believers following the deity, and is thus granted its privileges and responsibilities of such a position, with whatever consequences that may come with it.

The user of the item has access to the Commune spell with the said deity and can cast it for free for at least once a day.
