Protean cogs are protean items used to train Invention. They were first properly available on Treasure Hunter from 26 January 2017, though they were added to the game API (and temporarily to the game as a glitch) over a month earlier on 19 December 2016 (update).
The Invention Tutorial is required to be completed to be able to use protean cogs.
At most 60 protean cogs can be manufactured with one interaction and each takes 4.2 seconds to manufacture.
Like other protean items, cogs can be converted to other protean items at the rate of 3:2.
- It was re-released on 7 March 2017 as a 2nd Chance Tuesday promotion.
- First available from 26 January to 30 January 2017.
Level 1-4 are excluded as completing the Invention Tutorial will advance the player's Invention level to level 4.
- Protean cogs were a possible Treasure Hunter prize for a short time on 19 December 2016 until they were removed with a hotfix.
