The volatile clay tool is an item obtained by playing the Stealing Creation minigame and requires level 50 in the appropriate skill to use. When the tool is operated, it will randomly transform into one of the following tools: pickaxe, hatchet, harpoon, butterfly net, hammer, needle, or a fletching knife. Since 8 October 2013, one may store 29,340 bonus experience by transforming the tool, causing the player to earn double experience in that skill until all stored bonus experience is used up. All versions of the volatile tool can also be used for normal actions (such as a knife for Fletching, or a hatchet for Woodcutting), but once the bonus experience is gained it is not necessary to carry the discharged tools around to benefit from it.
