If it's a unit that you want to get to SA10, or is already at SA10, always bottom right.


 * Bottom right path - biggest boost, 4 stars to unlock (criticals, additionals, or dodges), requires the unit to be SA10 to be fully maxed.


 * Top left path - 3 stars to unlock (criticals, additionals, or dodges), doesn't require the unit to be SA10.


 * Top right path - 1 star to unlock (type ATK boost or SA boost)


 * Bottom left path - 1 star to unlock (type DEF boost or healing boost)

If you keep your finger pressed on the stars (or any other icon), they'll tell you exactly what they have to offer.
