Occult Crescent is great but the relic grind is the worst of both worlds.

This is the main problem, some have all of them, several times, others have 1-2... i would grind a week more, but give me pity or anything... RNG is sucks in this game, always.

But you don't need to grind. You get them passively when levelling and levelling the other jobs. Why do you need the relic right now? I don't get it.
