White Knight´s training places?

there's no point in throwing one point in blast, at all

do 1 rush 1 divine shield, 2 acb

then max acb, then divine shield, then worry about blast

Lv1 Blast is there only because it's better than Power Strike + IF. A lot better. It's optional though.

Personally, I think Lv3 Divine Shield has too low an activation rate (6% I think) to warrant that one point so early...
