It is worth it if you are lucky!

I have put in 20 million on materia for my relic, 14 million failed. and Im still only 30/31 det 40/44 Crit
It wasn't worth it for me at all. I never quit when I want to do something, like getting best stats. But for like my first time I quit that stupid thing because losing 12 det IV in a row made me sad

I don't mind rng much, I would much rather farm 100 atma if they removed the possibility of failing and losing materia. But when rng makes you lose that much gil, then it's so stupid
