{{items:bonecrusher.png?nolink|Bonecrusher}} **Bonecrusher** When carried in the inventory, if the player kills a monster that drops bones, the bonecrusher will automatically crush them, granting the player the same [[skills:prayer|Prayer]] XP that you would receive for using them on an altar. The Bonecrusher is an essential item for any account with longterm goals. It is very useful when killing [[guides:dagannoth_kings|Dagannoth Kings]], [[npcs:lava_dragon|Lava Dragons]], [[npcs:frost_dragon|Frost Dragons]], or any other type of [[npcs:dragons|Dragon]]. The Bonecrusher can be bought for 2,000 [[skills:slayer|Slayer]] Points at any of the [[skills:slayer|Slayer]] Masters. Unlike OSRS, the Bonecrusher has unlimited charges. The Bonecrusher will return to the Refund Box on death for regular players, and normal [[guides:misc:ironman|Ironmen]]. It will however, completely disappear on death for [[guides:misc:ultimate_ironman|Ultimate Ironmen]].
