First off, are Airship Voyages the only way to get fine alumen? If they are, then is there a decent strategy and/or airship build for obtaining them? Finally, is there any reason to use Viltgance parts? Ours have just been gathering dust in the FC chest for years. Guessing I'm not the only one with these questions. Hoping someone will take pity on me and share what they know. Thanks!
