For me it’s proof of hero
Recently I decided to lvl Alex to his final ascension the thing is I don’t have enough proofs to ascend him.
And whenever I want to lvl Gil skills I dont have enough, whenever i want to lvl Herc last skill (he’s 10/10/7) not enough proofs.
Is there ANYTHING that doesn’t require them in stupid quantities?
These things seem to hate me as they rarely drop when I farm them.
So then which mats do you hate or annoys you the most?
