Excuse me, is there any one who knows how to deactivate the code for the experience multiplication, I just want to turn the EXP x256 off so I get normal XP cause I want to work my way up with the Magic Knight class fairly, but I don't want to wait forever to level up the 3 classes needed to 30, any help please? Cause if I shut it off normally, I still receive the x256 EXP effects
