that's unless it's a good eidolon...
would love it if a 100% eidolon, SSR dragoon, an echidna (she's lv85 for me), or another fafnir (cause i recently drew my 2nd one) pops up...
plus, loading up 3k coins nets you magic jewels too so it's not too bad i guess...
if it was one of each guaranteed, it easily would have cost at least 6k coins...
