I'm a red mage main, and have only recently started putzing around on my thief inside abyssea.
My ninja is a support job only, as I don't have any fondness for the job myself, and my ninjitsu skill is, sadly, terribly gimped.
It's not that I'm unwilling to go and ungimp it, but the only reason to do so would be to proc grellow, and I was wondering:
Is any form of magic accuracy / ninjitsu skill required to proc grellow with ninjitsu?
I'm guessing "no" for the elemental ones, but possibly so for Kurayami?
