Is "Grit" a proper name for a DRK ability?

[Ultimatecalibur]

I think there will be quite a bit of Localization involved to lose all those Dark prefixes.. would make autotranslate for these abilities rather annoying. If I could choose at the moment, knowing what little we know:

Grit => Bravery
Darkside => Deathbringer
Dark Arts => Darkness

Just a few Tactics and FFXI references.. idk.. At least Souleater made the cut, that's enough to please me.

Darkside is used for the name of the sac hp deal more damage attack in VIII, IX, and The 4 Heroes of Light so the name is in itself a reference.
