The alchemiser is a machine that can be built in the Invention Guild basement at level 72 Invention. It automatically casts High Level Alchemy on the items put into it, even while the player is offline.

Every hour, on the hour, the alchemiser will process up to eight items deposited in it, consuming up to 45 machine charge as well as five fire runes and a nature rune. Building it requires 20 of the power allotment supplied by the generator. It can hold up to 1,500 items over the three input slots, and up to 1,500 nature runes and 7,500 fire runes. Researching the alchemiser blueprint awards 56,862 Invention experience.

Once the alchemiser has processed some items, the resulting coins may be withdrawn via the machine management interface. However, no Magic experience is awarded.

At level 108 Invention, the alchemiser can be upgraded to the Alchemiser mk. II.

Analysis[edit | edit source]

The alchemiser processes eight items per hour at a cost of 45 machine charge. Thus, each item costs 5.6 machine charge to process - an equivalent of 97.1 coins per item. The alchemiser also requires a nature rune and five fire runes for each item, increasing the cost to 1,054.1 coins per item. This is an additional cost of 692.1 coins per item compared to normally casting High Level Alchemy with a fire staff.

The alchemiser processes 192 items per day at a cost of 1,080 machine charge (approximately 0.36 divine charges). When completely filled, it will take 7 days 20 hours to alchemise the 1,500 input items, using 8,460 machine charges (approximately 2.82 divine charges).

The alchemiser mk. II is significantly cheaper to run than the mk. I, as the mk. II does not require fire runes (and is of a similar machine charge cost) - each item costs 465.5 coins to alchemise in a mk. II.

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.
  • patch 14 September 2020 (Update):
    • Untradeable items can no longer be duped using the Alchemiser Machine.
  • hotfix 21 December 2017 (Update):
    • Players can no longer place augmented items into an auto-alcher machine, as this causes them to lose their perks and item XP when the item is removed.

Trivia[edit | edit source]

  • The Alchemiser continues to process even if the player has run out of membership.
