The board itself is mostly pretty good, but the requirements for the connections are way off. There shouldn't be a required element of the clue that is not necessary for the 4 entries in the row to form a coherent group - e.g. the "elements without etc etc" should just be "elements." and the "planets without a circle" should just be "planets". It makes no game sense to add in superfluous requirements in the connections.

Agree with Brodiefish, with the addition that the celestial bodies group should also accept deities.

(Also, it seems really odd to have a grid that requires overly specific connections for some groups, but that has one group (gold) with an unusually loose connection).
