Possibly I guess, you would need White Versal Materia & 7x Black Crystals, so I'm not sure if it would be any more beneficial than Orbis Exchange quest for example.
Right, so then I'm not sure why he said "it also is not dexless if that is what you mean" because I was talking about Night Raven's Claw being a new endgame equip.
Sorry I might be wrong, I just assumed since you upgrade it using a ravens claw (that requires dex for usage), it does indeed sound like it will make the hermit life a lot easier.
