Fish oil

Fish oil was the natural oils extracted from the bodies of various fatty fish. It was used in alchemy, ship-building, tool crafting, and as a spell component. "We deal with magical crises, threats to the very existence of the Realms, wild creeping horrors that seek to devour all Waterdeep—that sort of thing. We do not fetch down cats from balconies where they've fled because their owners wanted to bathe them in fish oil. Fish oil is best used for romancing mermaids."

Description

One noteworthy producer of these oils was Tethyr. The Guild of Fishmongers and Fishermen had warehouses on the eastern docks of Tulmene that were filled with fish oil and could be smelled from afar. The town of Port Kir, like many other port cities in Tethyr, produced fresh and salted fish, as well as fish oil.

Uses
