The bone brooch was released to players on 18 October2010, upon the completion of the Halloween event. The reward was chosen by players in a "Guaranteed Content Poll". It allows the player to morph into a pile of bones when worn, although these bones appear different from a real pile. If a player is attacked while wearing it, they will automatically unmorph. As it is an untradeable holiday item, if lost it can be recovered by speaking to Diango.
When playing a game of Great Orb Project, the message will read "You're here to collect orbs, not turn into bones."
While in combat, the message will read "During a battle is rarely the right time for fashion experiments."
When peddling at the Blast Furnace, the message will read "You don't think you could pedal effectively if you were just bones."
During the 2011 easter event if you wear the brooch when standing where the roots of the evil trees spawn in the easter event area, the bones will "jump" away and you will unmorph.
The interface when a Bone Brooch is equipped.If you attempt to wear the bone brooch while you are stunned from picking pockets, your chatbox will state that you cannot transform while being bound by magic.
If you attack a non-aggressive NPC, then immediately morph, your avatar appears to have bones falling out of it. This glitch can also be performed by "whacking" another player (with the rubber chicken or easter carrot) and quickly morphing.
It is possible to teleport as a pile of bones if you morph, then quickly switch to the worn equipment tab, and right click any teleport jewellery. The jewellery's right click menu should stay open even while the avatar is in bone form. This works for most teleport jewellery - e.g. cabbage-port, the amulet of glory, etc.
When opening the equipment screen, although the Bone brooch is worn-and there is the option to wear it, you get a message in your chat box saying that the Bone brooch can't be worn. This is because the Bone brooch is never actually worn, clicking on wear simply transforms you.
There is a glitch when you cabbage port and repeatedly click the bone brooch, you will turn into bones instead of coming out of the cabbage.
While in bone form, you will not die of thirst in the desert until you change back which, if left for awhile you will be immediately effected by thirst. This can be used to heal some life points.
While in bone form vyrewatches will not notice you and demand a tithe (only the non-aggressive ones, not the ones near Burgh de Rott).
If you morph in the Dorgeshuun caves without a light source, the message about the bugs biting you comes up in your chat box, but no damage is done until you unmorph.
The bones you turn into look very similar to regular bones dropped by most NPCs, except you also drop with a skull.
