Point of Interest: Darkwater Spring (a Sept-umbra creation) (Patreon)

This spring, found within a temple to a god of darkness, produces magical black water. It's helpful to immerse yourself in it before delving into places with constant darkness.

This is my creation for day 21 of Sept-umbra.

Updated May 2021: Recategorized as a point of interest, rather than a magical item, and given a more detailed description for DMs to use in their games.
