Nin vs. Brd

[free_lancer_]

All ninjutsu (not mudra, btw, the mudra refer to the individual symbols that compose a ninjutsu) except Fuma Shuriken are magic. To verify this, you can go against levi EX and see which ones that tail reflects.
Raiton, Katon, Hyoton, and Suiton are all magic, and thus affected by Foe's and anything that limits magic. This makes DPSing fights like Levi very, very tricky.

It also makes other fights such as T11 annoying too. Because the Sphere takes 50% dmg on Magic and the Cube takes 50% less dmg on Physical. So NIN DPS gets a slight loss when they're fighting the Sphere.
