Absinthe

Absinthe 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).

It causes a green flame to flare at your feet for a second, then gives a blurry "drunken" effect that compounds with multiple uses within a short period. Other than the flame it is comparable to Hunter's Ale or Dwarven Ale. If enough Absinthe is taken, it causes your character to do things that you never commanded, such as dance, cheer, sit etc. It will also cause you to say things that you did not type, appearing above your head, but not in the text bar, such as "I Love You Man" "Oh No, Not Again" and "STOP SHOUTING."

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.
