>>6465125gK.Y.Fl or gK.2G.Fl would be decent, with Neptune being a very good defensive Layer still it would also pair nicely with the same sub-parts. As far as attack goes, gV.2G.J would be a semi effective combo. But yeah, try getting Atomic.
>>6468288For stamina there isn't much good stock, so Blaze Ragnaruk, for defense Tornado Wyvern, though it's difficult to obtain so alternatively Acid Anubis, for attack Killer Deathscyther or Victory Valkyrie, for balance Legend Spriggan or Alter Chronos.
