Just talk to her with Ike in the chapter where you have to fight bird laguz on a ship.

He isn't as hard as The Black Knight but be sure to call in a Laguz Lord i nthat battle and use him to help you. I think Giffca is the best choice.

The Dragonfoe skill scroll, two coins, the SS ranked dagger Baselard, a White Gem, a Laguz gem, and a Daemon card.

It depends if u like all out attacks go for the laguz people but if u like strategy go for things like the archsage marksman and Gold Knight

But they are characters who are overall better than others, such as, Haar, Gatrie, Nephenee, all Laguz kings/queens etc

If You like people (beroc) the number 1 best person is Harr. Because when you level him up, we won't get hit and if he dose he won't get hurt very much. Other People are Shinon, Soren, Gatrie, Titania, Oscar And Byod. Royal Kinghts, Nephenee, Brom and Pelleas. Otherwise everyone else sucks.

You can't. level 20 is as high as it goes. Well it was until Fire Emblem: Radiant Dawn. Transforming human/beasts known as Laguz can go to level 40. You CAN however use a Master Seal, Knight's Crest, etc. to evolve a character above level 10 to a new, more powerful class.
