When you say "difficulty" and "value/worth/cost", what exactly is the difference in these? you say the the value is the variable for rarity, i understand, but then what will difficulty represent?
A general relative skill level. I think mostly this will be used for training levels but may have other uses. Perhaps there is also a primary/secondary stat requirement that is affected by skill level. So no matter how much training you have you can never be a "insert dexterity requiring skill here" if you have a super low dexterity. Or something like that.
The difficulty of a skill is different than how rare it is to find a trainer.
so there won't be any stat requirements, but there will be stats?
There will be stats. They may be requirements... or they may just control how affective the skill is or something. There will definitely be stats, though.
can't wait to see how all this ties together!
