Who is the best to marry your unit in fire emblem awakening?

Answer 1

While these were given to me by a friend, I've tested them and they've shown to be outstanding for Lunatic and Lunatic+ Mode. So it's only natural that I share what he's discovered:

Stahl x Cordelia = Severa

Kellam x Nowi = Nah

Chrom x Olivia = Lucina, Inigo

Ricken x Tharja = Noire

Henry x Maribelle = Brady

Frederick x Cherche = Gerome

Gaius x Lissa = Owain

Caius x Nah = Morgan

Inigo x Severa

Brady x Noire

Gerome x Lucina

Owaine x Morgan

Answer 2

It's not best to marry anyone in particular. Although I will say that there are pros and cons to marrying certain characters. I will give you a few tips though.

If you are to marry someone, choose someone you know you will use for the rest of the game. Married characters give very large stat boosts when they are paired with their spouse. So marry someone who's stats associate to yours.

If you are focused your child, I would say that marrying an adult female would be a smart idea because you get two units as your child, and their stats will be powerful since Robin is almost balanced. But I would still say it's also a good idea to marry a child unit too because you can give your child the stat boosts of Robin, the Spouse, and the Spouse's parents.
