The Porta-Still is a crafting item used for creating alcohol. It is a starting item if the player selected the Alchemy Skill. It can also be found as a random item throughout the game, although it is more likely to be found in specialized "Alchemy" Rooms.
The Porta-Still can be used to create any of the Drinks found in game, by converting various fruits or Drinks into stronger beverages. It can also distill the more potent potables (and one specific mushroom) into Aqua Vitae, which is used in many alchemical recipes. Higher levels of Alchemy skill will result in more liquor produced for the same amount of raw material.
A minimum skill of 1 is required to use the still, as there are no 0-skill recipes for this item.
