so i want to know how to breakthrough a ninja to y+2.

i have sasuke normal

skill 2,3,4 is max

skill 1- +1 and y open

skill 5- +1 and y open.

so skill 4 i went from +0 to +2 by 50+ 50 frags, skill 2 and 3 i got max from vials.

but now when i try to upgrade skill 1 and 5. to y+2, the y version of these skills are not clickable in skill breakthrough tab but only the +! version of these skills are clickable..

so if i do +1 to +2 with 200 frags, will i get y versions +1 and +2 usable as well?
