Discovery interface (step 1)
Discovery is a mechanic of the Invention skill, where players research blueprints of materials, devices, and machines used in Invention. Discovery is done at an Inventor's workbench, and involves an optimisation puzzle to maximise experience gained by discovering the blueprint.

Discovering blueprints is affected by bonus experience, the Wise perk, and Double XP Weekend. Malcolm cannot be obtained from discovery.


The discovery process is a 2-step puzzle. The puzzle is randomised when started - switching to another blueprint or closing the interface results in a new solution.

Part 1

The five 'materials' need to be selected from the 10 presented. These can be dragged into the slots, or just clicked. Once the 5 slots are filled, click the prototype button to check - some of the materials will be rejected and removed. Repeat until all 5 slots contain the correct material to move on to part 2.

This part can always be completed in 3 prototypes:

  1. Add any 5 materials to the board and click prototype
  2. Remove all materials from the board then add the other 5 (that have not been tested) and prototype again
  3. Re-add the correct ones from step 1 and prototype
Part 2

The second part is about finding the correct order of materials in the row. The materials can be moved around by dragging them or clicking one then clicking another one to swap with.

How optimised this is - poor, satisfactory, good, very good, excellent, or perfect - determines how much experience is granted by researching, from 20% to 100% of the maximum experience (values listed in the table below). Poor configuration results in 20% of the perfect experience, satisfactory 40%, good 60%, very good 70%, and excellent 80%.

Discovery example

Top: All materials are in the right place
Middle: Materials 4&5 are adjacent and ordered, materials 1&2 are adjacent but not ordered
Bottom: Only materials 3&4 are adjacent, but they are not ordered

A (hidden) score is assigned to each configuration, which corresponds to the optimisation level (Poor, Satisfactory, etc.). Points are given for how many of the materials are correctly adjacent, as well as if they are in contact in the correct left-right arrangement. See right for an example of this.

Tips for this part:

  • 'Excellent' to 'Perfect' is one swap, so repeatedly make a swap, then swap back if it is incorrect. Systematically eliminate swaps by moving left to right: swap the first slot with the other 3 (and back), then the second slot with the 3 to its right (no need to swap with slot 1), and so on.
  • Generally prefer swaps that result in the optimisation improving, or at least remaining the same. Switch to a poor optimisation only if your current one doesn't appear to be going anywhere.
