Sacking a Hector

Myrrh myrrh myrrh

Sheena! I've always envied good Sheena builds as all I ever get is +Spd on her, I can even make a 4*+10 and they're all +Spd. Myrrh is less common for summoning but makes a ridiculously flexible tank.

Ayra is hard to summon for but she's also quite the monster with Slaying Edge + DC as it makes anyone who attacks her get a near guaranteed Regna Astra back. Joshua is the other red and he's F2P to boot.

Blues are more niche than other colors (I think). Effie makes good use but really that's just 'cause armor emblem. Jagen is a mage counter with it, but Fjorm is much lower investment with better BST. The spot for blues is kinda saturated without any clear winners.
