It is true that Caloric Stone can be gained multiple times. The guild members said that "We can get it after the use if we can get rare metal from seven hidden mines again.".

Also, if there's no way to get "Twenty" multiple times, there's no point to gather information about them (because once it is used, it will never work again in YGGDRASIL.). So it's reasonable to guess "Twenty" can get again by certain way. Of course it will be really hard way, and as the world class item must be unique, it seems that if there's unused twenty, then no one can the same item even if one knows the way to get it.
