1. There should be a text saying whether or not you have a study desk near your "Study Report" in the Character Sheet. (if different types of Desks are implemented, it should say which one you have.)
2. Different types of Desks/Desk progression. There could even be tiny (3x3 or 4x4) Desk that requires only boards/blocks.
