Potions in the indie computer game Minecraft are bottled substances, many of which give the player some kind of effect. For example, a potion of regeneration gives a status effect that increases the health of a player or a mob. The base item used to create potions is a water bottle. A water bottle can be obtained by fishing it with a fishing rod or by using a glass bottle on water. The Minecraft cursor and game pointer with Water Bottle and Potion of Regeneration!
