Vial of Absinthe

Vial of Absinthe (formerly just Absinthe) is an item available during the Halloween 2005 and Halloween 2006 special events. It is traded by several Halloween collectors in severals cities in Elona and Tyria. In addition, Absinthe is handed out as a random prize for players who obeyed the Mad King when he appeared at Lion's Arch and Kamadan.

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. The screen will also turn more green the more drunk you are. Other than the flame it is comparable to Hunter's Ale or Dwarven Ale.

Halloween collector items, purchased or received from the Mad King, will remain in each character's inventory until they are used or destroyed.

Additional Note
Absinthe is a real beverage available in the EU, legal to possess in the US but not for human consumption.
