- Corrected some minor mistakes

5. Feb 2021
- Added all maps where there is no secret hidden loot as well into the guide, just to clarify it better for the reader, if there is something to find on a map or not.

These are the blueprints that can not be dropped by enemies, but only be looted in specific biomes in certain secret places.

If you are looking for a specific one, the number in brackets tells you the respective stage it will appear in. Scroll down to that Stage to find it's exact location.

(For more blueprints that are exclusively dropped by the Bosses take a look at my Boss Loot Guide.)
