Night-Eye Potion

Description
"She strained her eyes into the blackness beyond the rim of the dim light, tense with fear of what she might see. A whimpering gasp escaped her lips. The darkness was taking form. Something huge and bulky grew up out of the void."

- Xuthal of the Dusk

Some creatures have perfect vision even in the darkest of environments. Through the power of Jhebbal Sag, this potion confers the benefits of such night vision to the imbiber.

This gives an obvious advantage to those who would creep up on enemies during the darkest of nights, but also allows for freeing up hand during dungeon exploration.
