Foul Water (Magical Liquid)

If this liquid is consumed, the imbiber must save vs. poison or become ill for three days. The liquid is intended to be added to other liquids to change them into stale, undrinkable water. Further, foul water doubles the potency of poisons and ruins magical potions. The contents of a single container can change up to 1,000 cubic feet (7,500 gallons) of pure, fresh water into polluted, salty water. It turns up to 100 cubic feet of wine or oil (750 gallons) into mild acid. The effects of the potion are permanent, although the liquid may be purified magically after an initial period of 5d8 rounds.
