Weapon Refinery Buff for low tier units

Corrin F is now one of the best mixed tanks in the game. Young Tiki does have more defense than her by 1 but Corrin has better speed for preventing doubles and has a better meta color.

Her res stat would only matter when facing dragons so pair her up with a falchion user. Because her def stat will act as her res stat against staff users and mages, she is really only countered by strong greens and dragons. Falchion users being her best partners because they can counter Corrin's weakness and provide healing.
an attack stat of 41 is lacklustre (with steady breath) but will rely on bonfire/ignis for kills. With a total of 48 defense, and considering the low res of a lot of meta threats, she can take out a lot of the cast with a boosted ignis/bonfire.

Azama can potentially solo a team if they all have a res stat under 28 (at least against my -atk azama)

I already have this fully built and just need to refine his weapon. He can pain down one unit by 10 hp and the rest around him by 24. Assuming he attacks a faster bow user, he will have 3 charges of miracle. Then enemy phase, same unit attacks him, hopefully he survives and now has a fully charged miracle and he can pain a unit near the initial target. Now assuming all units have 27 or less res, Azama would have pained them all down to 1 HP and he can finish them all off on vantage turns. If a single unit has a high res stat, thats where miracle comes in and someone else can go ahead and handle him. Otherwise, he can blow all their HP down effortlessly and potentially sweep a team.
