I always have units with excellent IV when it comes to fodders. My only H!Henry was +spd -hp, W!Tharja was +atk -hp, Hardin +atk -hp, and now Hector +atk -hp as well.
I don't care about Hector and Hardin, and have made my decision when it comes to Tharja. But the problem is whether or not to kill Henry. I need the Armor March to make sure that M!Grima function at full potential, and I don't really seem to be using Henry that often. But on the flip side, I have invested quite a few into him (feathers), like Owl tome and QR 3. Is it dumb to kill him at this point?
Honestly, it’s up to how much you’re going to use Grima. If I were you, I’d roll for Amelia and fodder her or put Henry and Grima on the same team. This may not work as they’re both magic greens but Expiration has adaptive damage so meh. Just pack a good blue (like Hardin, or a Brave Lance Effie to secure kills on reds assuming your doing Armor Emblem but go for Reinhardt, Henry, Grima, and a red/bonus unit (Alfonse maybe) if you’re not.
