Witch's Brew

Witch's Brew is an item included in the Halloween 2005 update. It is traded by the Necrid Horsemen Halloween Collectors in each of the major cities (except The Amnoon Oasis). In addition, the Brew is handed out as a random prize for players who obey the Mad King when he appears at Lion's Arch.

It causes a blurry "drunken" sensation for a short period of time, different and much stronger than that of a single Absinthe or Dwarven Ale. Drinking multiple batches of witch's brew may cause unpredictable drunken behavior such as random emotes or text bubbles above the drunken character's head. The screen will also turn more orange the more you drink.

It is unknown how long this will be included in the game. Most likely it will be removed after Halloween. This may make hoarding it now and selling it later quite profitable.
