Black Santa hat was removed from RuneScape after an update, but still exists in-game for those who had obtained it.
The black Santa hat, also known as BSH, is a tradeable discontinued item players were able to obtain during the 15 Days of Christmas mini-event, starting on 20 December2013, ending on 3 January2014. The hat could be obtained by pulling a festive cracker, with a drop chance of 1 in 2,000. Wearing Christmas themed items increased the chance of crackers dropping while training any skill by 20% for each festive item equipped (for a maximum of 120% increased chance).
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.
Before its release, Mod Matthe transformed his character into a black Santa hat and moved around Lumbridge, showing the item's appearance to players.
When a player received a black Santa hat from a festive cracker, special fireworks would appear above the player and a server-wide announcement was made, saying: Someone pulled their festive cracker and received a black Santa hat!
The black Santa hat is the most valuable discontinued item to be released since 2002 and the second rarest (only surpassed by the holly wreath), making it one of only two modern discontinued items to surpass the values of the h'ween masks and the original Santa hat.
