While I’m definitely getting a little bit burnt out on Corrin right now, I’ve been thinking on a build to work towards for her considering the beautiful resplendent art we’re getting here shortly. My thoughts so far are as thus:
Good god the investment needed
Got the spec buff and debuff with her refine and C-slot, and A/R Finish buffing her weakest stats with sustain and a bump up to her damage. Moonbow and D. Wrath to capitalize on Finish and to help deal damage.
My other thought was some kind of support build considering her ATK and RES are frankly garbage by modern unit standards, though I only got as far as D/R Unity and maybe, Goad Dragons?
