it could be "technically possible" if the main changes were not limited but for now you have to pay if you want to do it more than 2 times a day, as for now every main can master 2 elements and even then oasis doesnt let us mix and match talents at will.

i meant talents of the same main like for example how i cant use shadow clone jutsu- ultimate and wind style enhancement because i have to use wind and fire straighten instead, its either all fire release or all vanilla ones, that is what i meant for mix at will.
