I've sunk an easy 10-12 hours into spamming fates in Yak'tel, and I've been sitting on 2 Malachite for weeks.
Sunk another half dozen hours into the Crescent itself (Which I hate for its own reasons. Run to Fate/CE, get nothing, /return, teleport to nearest shard, Run to Fate/CE, get nothing, /return; Ad Nauseum) and got absolutely nothing.

How hard would a pity system be?
You fail a Fate/CE. Get buff: "Your efforts of searching make you keen to the gleam of Demiatma, increasing your chances to find them by 1%".
It stacks per fail; and when I finally get 1, I lose all stacks.

At least then, I know that EVENTUALLY I will get one.
But as it is, I could be grinding this until 8.0 and still be stuck on this quest. It's pathetic.

I have no incentive to even try, because I don't know if ANY of my time and effort will be rewarded. I can (And Probably Will) be doing these for another dozen hours and get nothing.

Congrats to all those who got lucky and actually get to progress their relics, lucky you.
The rest of us don't, for no reason other than the game shrugged and went "Lol nah"
