5/5 Magic Accuracy
5/5 Chain Affinity

5/5 Assimilation
5/5 Enchainment


Currently the optimal solution. For group 1, 10 magic accuracy is infinitely more useful than 10 physical accuracy. Unless they add a Composure effect to Diffusion, it simply isn't worth it considering the short duration of most BLU buffs and the redundancy of the two that are of a decent duration. 50 extra TP on Chain Affinity is a reasonable boost to spell damage on quite a few of our current best spells.
