you need to kill leeches in certain areas and one of them will drom carbuncle's ruby, then you give it to someone in windurst and you get sent on a quest to experiance all 6 weather types. once you see each one you see a cutscene and the ruby glows, after you see them all you can be a smn and summon carbuncle. he's the only non-elemental. and it doesnt matter anywho cuz you can always un-summon and then summon something else to adapt to your enemie's str and weaknesses. Hes not non-elemental, hes light element. White light is made up of the 7 colours of the visible spectrum. Thats y u have to collect all the types of light to summon carbuncle. Make sense?
