So your idea for the curio system is a little bit confusing to understand, so please correct me if i misunderstand your points.

I think the ability system is fine as it is. Getting "level ups" to them more of an advantage to larger groups who would be able to bot forageable crios/who can mass collect them, and in turn be able to "level up" faster. Also, adding "level ups" to the curios would be pointless if one of the points for using lp is to put into abilities, so it would just add a huge buff to curios. With the exp, giving curios the ability to give exp would be pointless because the whole point of the exp system is so that you have to get exp before you can study a curio.

IMO if you really feel strong about your idea, I recommend rethinking it. About this part, I do like the idea of making some curios more valuable or limited, making them equally accessible by all players making them good for trading. So maybe integrating the fate system(if i understand what it is) a bit more to the current game could be interesting.
