SB is part magic and Phyical at the same time the phyical part take the element of his wepon the magic part stays neutral
Which makes it almost impoisble to reduse to 0 the only bad part it can be use with any wepon it has no special wepon that requires
to cast SB for.
U can even cast SB with bare hand and do insane dmg >.>
And no one thought this was broken in so many ways =P
