So, as promised, I powered my way through Scarlet Blaze a second time, but with all of the units I recruited starting out in the mid-40s to do it again on Hard difficulty and fill out the support conversations I didn't get the first time. The "recommended level" curve for the Hard versions of levels is steeper than the ones for Easy and Normal. It looks like for every level increase between maps on Normal, the Hard mode versions go up by two. By the end of the game, the enemy levels top out in the low 100's, and I sure as hell wasn't going to do
that much grinding.
Keeping all of my bonuses from New Game+ came with the added benefit of a fully-upgraded base camp, so I can spend more time training and unlocking new skills for my generals. I even stumbled upon "innate abilities", which work almost like Budding Talents from
Three Houses where you train a skill outside of the given unit's area of expertise to learn a new spell or ability. The first two I got were "Nullify Magic" for Edelgard (which allows her to no-sell
all magic damage after training her as a Gremory), and "Gather" for Monica (which clusters enemies in front of her whenever she starts an attack combo, allowing her to blast them all at once with high-damage area-of-effect spells like Aura and Hades; I got this one by training her as a Trickster). I have a feeling these skills are going to be essential to surviving the game on Maddening difficulty, so I'm teaching as many of these skills as I can to my party members while I have them.
Despite the enemy levels starting to outstrip mine by Chapter 12 or so, I still managed to get through and earn S-ranks by upgrading, "reforging", and "unleashing" my best weapons at the blacksmith, which I'd mostly ignored in favor of finding and using the most powerful weapon drops. Even with levels in the high 60's while the enemy had triple digits, going into battle with +30 forged weapons was enough to close the power gap (though I still got knocked around a lot by the final boss).
After completing my second Scarlet Blaze run, I chose to do Golden Wildfire next because I'd recruited most of their members in SB anyway, meaning I didn't have to focus on leveling them up or grinding for their supports. And you know what that means!
