The Brew of the Depths is a drinkable potion that allows the drinker to breath underwater for around 5 minutes. The think to beware of is that for the duration the drinker will no longer be able to breath air! This effect will be removed only when it expires or the drinker dies. Milk does not clear the effect.

The Brew of the Depths is created in a kettle using the recipe found in the book Witchcraft: Brews & Infusions. Into the pot, throw Mandrake Root, Tear of the Goddess, Water Artichoke Globe, Lily pad, Odour of Purity and an Ink Sac.

Wear a Witches Hat (and robes) while brewing to get a chance of double brewing.
