Interesting. And I'd say no, but I'm not familiar with the armor. Magic is a wasted state on the MC.
Here is the info I was referring too. Not sure if this person was just trolling but Ive read this response a few places:
Only put points into Magic for the MC if you want to use the Masakado armor for the MC, as it requires 10 Magic to equip. It has the strongest defense stats.
I would invest into a few points into Intelligence for the MC, since it gives magic defense.
Nemissa should be focusing on Magic/Int and Agi mainly. Put a few points into Endurance if you feel like you're taking too much damage. Nemissa is usually your primary damage dealer, so stack those points into Magic for higher output.
