Auto disassembler mk. II

The auto disassembler mk. II is a machine that can be built in the Invention Guild basement at level 81 Invention. It automatically disassembles items put into it, even while the player is offline.

Every hour, on the hour, the auto disassembler will process up to 60 items deposited in it, consuming up to 230 machine charge. Building it requires 40 of the power allotment supplied by the generator. It can hold up to 13,000 items over the three input slots. Researching the auto disassembler mk. II blueprint awards 5300 Invention experience.

Items which are disassembled in batches count towards the item limit as once per item, not once per batch. For example, arrows are disassembled in batches of 50. This machine can process a maximum of 13,000 arrows, not 650,000.

Once the auto disassembler has processed some items, the resulting materials will be placed in a pouch of components in the output slot. When the pouch is withdrawn, all the materials (including junk) will be added directly to the bag of materials. The auto disassembler also accounts for the player's researched level of junk chance reduction, but the Invention master cape perk does not apply to the machine.

Analysis[edit | edit source]

The auto disassembler mk. II disassembles 60 items per hour at a cost of 230 machine charge. Thus, each item costs 3.8 machine charge to process - an equivalent of 82.3 coins per item.

The auto disassembler mk. II processes 1,440 items per day at a cost of 5,520 machine charge (just under 2 divine charges). When completely filled, it will take 9 days 1 hour to disassemble the 13,000 input items, using 49,910 machine charges (under 17 divine charges).

Update history[edit | edit source]

This information has been compiled as part of the update history project. Some updates may not be included - see here for how to help out!
  • ninja 14 December 2020 (Update):
    • Players will now receive log in and update messages whenever their Invention machines have finished processing their inputs, run out of secondary inputs, or run out of charges.
      • These messages can be toggled in the Login Messages or Notification Messages option menus.
    • Auto disassembler machines will now display the correct processing time for items disassembled in batches, such as ammunition.
      • The charge used to process such items will now be correctly calculated and consumed.
  • patch 9 October 2017 (Update):
    • Improved likelihood of receiving low chance components when auto-disassembling while logged in, to better match chances with regular disassembly.

Trivia[edit | edit source]

The animation the auto disassembler mk. II has in the Invention Guild shows it disassembling a myriad of superior dragon weapons, even though those cannot be disassembled.
