So guys, I've looted a lot of Idolaspheres and got several Master Seals. I want to get all the good session skills by switching each character to both options and get all the good skills. Question is, if it is adviceable to do it now in the middle of Ch. 5, or should I get all the class exclusive skills and then switch to the other option?
An extra question is if one gets unlimited Master Seals at some point of the game?
