Fire Emblem is a difficult series, I don't know if you guys have heard

[Hyperion]

Oh, I meant to say I used the Knights crest on Oswin.
I used the earth seal to promote Florina Xd and then I used the pegasus/wyvern seal to promote Heath.

IIRC, I sold one of the seals XD, because I didn't realize I HAD to keep them for characters, lol. I always sold them in PoR/RD because they were useless. Lol, I'm so stupid. I'll be more careful in my second play through.

What do you guys recommend. Should I go straight into Hector's Hard Mode? Or should I do Lyn's?
Also, how does the funds ranking work in this game? I just want to know for future reference if I ever want to do a perfect run.
