Gillywater

Gillywater is a herbal preparation in nature, where Gillyweed is added to water to 'brew' like a tea. The resulting solution is a blue-green translucent water like potion that harnesses the effects of Gillyweed and amplifies them so that the person consuming the potion has these effects for a longer period of time. Like Gillyweed, Gillywater allows the person who consumes it to navigate underwater environments with ease and style.
