Blue Mage and the value of Spell Speed

[Kalise]

I doubt it will have much of an impact. The main stat you want for Blu is INT as this will increase the effect of Blu spells.

This.

It was mentioned, that BLU has additional affinity for INT scaling, so it's essentially, stack INT, INT and more INT.

(Also, buy up all the level 50/60 INT materia from the marketboard while it's still dirt cheap before everyone cotton's on to the fact that BLU wants to stack a whole heap of INT)
