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. During the Apple Jubilee promotion, there was a confirmation prompt when attempting to manufacture the cogs without a jubilee hopper. This prompt could be toggled off permanently.
