[@LuckyBlackCat] Ah, I don't think evolution stones will be necessary since Pokemon that don't have a specified evo level are all down to evolve at lvl 30. Stones and other means of evolution by item will probably just be an "optional" part of the process, although preferred since such be more "realistic."

So, I'd like to leave stones out of the RP for now. Maybe sell an item that helps with combat/level earning or such? One can never have too many items, and there's a wide array of them in the games :)
