A lot of people, including me have already beat Lunatic+/Classic. I'm currently working on capping my characters though so I have quite a bit of work to go even with 82 hr of playtime.
I beat the final chapter, Grima, in Lunatic+ in 3 turns with just Chrom and MU. MU and Chrom had Limit Breaker. MU was equipped with an upgraded Celica's Gale (9mt, 95hit, 5crit) and Chrom had Exalted Falchion.
well every stratagey is mosly luck or reseting until you get enemies with desired skills.
How'd you get past chapter 3 though, it was already almost impossible for me in Lunatic?
