Veil of Favor

Wondrous item, common

Price: 10-50 gp | low sentimentality

This semi-transparent white veil can be worn over your face. When looking through the veil, you see an undulating aura around intelligent creatures showing the amount of favor they’ve curried with the gods. A flat aura about one inch thick represents the average person who is dutiful to the gods. A sickly aura clings to those who have offended the gods while no aura means the gods have abandoned them and won’t answer their pleas. Those with thick auras or an almost overwhelming glow around them are favored by the gods due to great acts of piety or heroism, and they may even be chosen champions of a god.

Paid

When you focus on a single creature, you learn which god they primarily worship.

Overpaid

You also see glows around items which have been blessed or touched by a god and can focus on the item to learn which god blessed or touched it.
