During the 15 Days of Christmas in 2013, this item, along with other Christmas-themed equipment, were given the Hybrid style of combat, and stats that scaled with the player's levels. This was so players could use these items in combat to assist in hunting for festive crackers during the event.
While wearing the full Christmas ghost set, ghosts in Port Phasmatys will assume that the player is a real ghost.
Although the full set resembles the outfit of the Ghost of Christmas Yet to Come (minus the chains), it is used by the player to assume the role of all three ghosts (Past, Present, and Yet to Come). The chains might resemble Scrooge's co-worker Jacob Marley who appears in heavy chains to warn Scrooge about the past, the present, and the future.
