Fire Emblem: The Sacred Stones - Max stats Demon King Fomortiis

Well, except move, anyway.
Inspired by Blazing Lion's video, I wanted to try beating the Demon King at max stats without hacking my own stats too. Luna isn't actually a must for this to work, ranged Sacred Twins(except Gleipnir) in the hands of a sufficiently strong user can work too, dealing less damage but more reliably. But since summoners are required anyway to force the switch to Ravager without sacrificing a unit, I went with Luna.
