Fiend Sight Lenses (Patreon)

Wondrous item, uncommon (requires attunement)

These blessed spectacles grant sight into the souls of the wicked. While wearing these lenses you have darkvision out to 30 feet. If you already have darkvision, the range of it is instead increased by 15 feet. Additionally, you can see a faint aura around fiends, undead, and those of infernal or undead lineage (i.e. Tieflings, Damphir) within that radius.

Though many would think these dark lenses would hamper the vision of their wearer, they conversely gain insight into the darkness of this world. Not caring to differentiate between creatures of the night or their offspring, the church doles them out to each member of the order who ventures into the world. If one can see into the hidden darkness, it is that much easier for the light to burn it away.
