The Alliance Alive HD Remastered (EP)

There are skills that are used on yourself and serve as a kind of counterattack (labeled Self). It is best to put the character you want to learn such a skill in a defensive stance and use a basic attack. There is also a nuance with shield skills, as far as I understand, the greater the weight, the stronger the ability the hero is able to learn. That is, for the latest abilities with a shield, load the character with everything you can.
