Disassemble

Disassemble is an Invention ability unlocked during the Invention Tutorial, located under skilling spells. When used on an item, the item will be disassembled into materials which can be used in Invention. It requires 1 Invention (which in turn requires 80 Divination, Crafting, and Smithing) and the Inventor's Tools (which are automatically added to the tool belt during the tutorial) to use, but have no cost. Disassemble can also be used by dragging the item over the Invention icon in the inventory; additionally, weapon and armour gizmos can be disassembled using their right-click option.

Both noted and unnoted items can be disassembled. Some items disassemble in batches - for example, most ammunition disassembles in batches of 50. Up to 60 batches (normally 60 items, or 3000 ammunition, etc) will be automatically disassembled per use of disassemble.

Analyse can be used to know what materials the item can be disassembled into, but using it is not a requirement to disassemble the item.

Limitations

 * Disassemble cannot be used at the following locations:
 * Inside Daemonheim, during Dungeoneering
 * The Wilderness
 * Underwater
 * Barrows minigame
 * Castle Wars
 * Disassemble cannot be used on items on the ground, present in the Loot tab, or in a Beast of Burden's inventory - they must be moved to the player's inventory first.

Not all items can be disassembled:
 * Attempting to disassemble crystal seeds (tool or weapon) prompt the message: "You cannot disassemble crystal seeds."
 * Attempting to disassemble items such as dreadnips and red chinchompas will prompt the message: "You monster! You can't disassemble a living thing."
 * Attempting to disassemble Tokkul will prompt the message: "The TzHaar would not approve if you disassembled TokKul."
 * Attempting to disassemble bolt tips will prompt the message: "You cannot disassemble bolt tips." Similarly, arrowheads prompt the message: "You cannot disassemble arrowheads."
 * Attempting to disassemble certain rare items (Off-hand rubber chicken) or high valued items (Blue partyhat) will prompt the message: "You could not bring yourself to destroy this rare item."

Trivia

 * Pets such as ravens will only yield the default "That item cannot be disassembled." message despite being a living thing. On the other hand, salamanders, seeds, and saplings can be disassembled.
 * A junk chance of 98% as well as a chance for simple parts (often) and variable components (rarely) appears to be the "default" result for disassembling items, as it could often be found on more obscure items.
