Oh nice, thanks.

Unless google translate is incorrect, it seems there's a new currency added which is gotten from selling R and above eidolons which is used to exchange for any past raid event eidolon and other items. Thankfully I got several spare past event dupes I can probably get rid of. Though I already got rid of all my old SR eidolons, probably should have kept them for it.
