For weapons for attack the higher the number the better, for hit% the lower the number the better, and for evade the higher the number the better. For shields attack and hit% are both irrelevant and the higher the evade the better. For a more detailed explanation of how weapon affect statistics, see the statistics page.

Note that people in the back row can not attack or be hit with physical attacks unless they are using a bow (then they can attack but they still can not be hit). Since a bow allows people to attack from the back row, which makes it so that they can not be hit, people with bows do not need shields and so can not equip a second weapon. Finally, note that Layla and Lionheart are left handed, so everything which is right handed for most people is left handed for them.

Mythril stuff can be obtained by giving the Mythril to the guy in Altea that's whining about the fact that he ain't got no dang mythril.
