I have some more questions: What is the best way to farm draconic eye shards? Due to several mistakes (i.e. not doing missions) I only have 12 when I need 30 for Gaia and will need 30 more for Titania later. Is the best way just doing missions every week?

Also, what should I do will all of the extra Prison of Wind Disasters (extra as in ones past MLB) I've been getting from farming wind raids for cores? Should I keep them until that eidolon orb shop thing? And same thing with the extra wheellock gale guns (although if I'm getting D'art eventually it may not be a bad idea to have multiple MLB of those, but I do already have a MLB wind SSR gun).
