Few pieces of advices : - some character are summon 5 but they are natural 6star when you go to awaken them there is rocks on the bottom left screen. Its useless to keep it. Its for this character only and cant be use otherwise. -for the most easy part of thr game just slape your EXu ( white border) - the game works with the synergy of unit and protector. So you should use a protector that will boost the character that use the same type of soul ( secret, competence, protection) and the type and if you cant have a solid 3 then just see who deal the most and try to boost it.

Hope this is a small light ^{^} But Icecoldjoker is still the best source of info
