Elder Cronos:
Oh well, what do I have to lose? Here is the list of ingredients you will need in order to create a Fairy Stone. Howover this cannot be accomplished easily, not even by a skilled Dwarven Artisan. I do know of a young lady named Maria who lives in the Town of Dion who can make a Crystal of Purity. I think she may also be able to make a Deluxe Fairy Stone... If she can't help you I am afraid you may be out of luck. But you won't know until you ask, eh? By the way, among the ingredients, the toad lord's back skin cannot be purchased. You must go to the Cruma Marshlands yourself and kill a toad lord to collect it.
