Ghost-in-the-Box

The Ghost-in-the-Box 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 Box is handed out as a random prize for players who obey the Mad King when he appears at Lion's Arch.

It causes a small ghost, something like a miniature Wraith to appear in front of you with a slightly startling noise and the word "Boo!" above its head, stay for a brief time, then disappear in a puff of smoke with another yell.

When the Ghost that was once in the box disappears, it's 'death' counts as a Necromancer's Soul Reaping death, and any nearby Necromancers with attribute points in Soul Reaping will gain back energy. Since the new Halloween Items can not be used in PVP zones, there is no possibility of this being exploited in PVP.

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.
