Ghost-in-the-Box

The Ghost-in-the-Box is an item included in the Halloween 2005 update. It was traded by the Necrid Horsemen Halloween Collectors in each of the major cities (except The Amnoon Oasis). In addition, the Box was handed out as a random prize for players who obeyed the Mad King when he appeared 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 rank 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. Also it attracts enemies attention so they attack the ghost instead. Warriors are also reportedly able to use "I Will Avenge You!" after the ghost disappears.

Halloween 2005 collector items, purchased or recieved from the Mad King, will remain in each character's inventory until they are used or destroyed.

As of Halloween 2006, testing shows that once the ghost disappears "I Will Avenge You!" can be triggered. Additionally, deploying 5 Ghost-in-the-box one after another, then activating "I Will Avenge You!" will extend the duration to 50 seconds, and so on. The Ghost-in-the-box's death still triggers Necromancer's Soul Reaping death.
