Where can I find Milky Glass Marbles?

Hello everyone, Cruger here! o/

As the title suggests, I'm curious of where milky glass marbles drop. Or rather, where one seems to find them more frequently. Also, it'd be nice for more areas to be noted as for as magatamas go. Thanks in advance!

recently i got some colour marble outside izumo (sadly no black so far /sob) as im recently grind there for weapon feed. but i cant really say the drops really there as im sure got several too in various place and dungeon.
so i still stay at my previous conclusion. since they are considered equipment, they pretty much random and we only can just go grind somewhere and pray.

easier looking for one you need at player shop , but yeah, prepare your OC

Izumo I shall stay, then. I hope it's not too bad, though. Really just want to get that "immune to critical" MT. Well if anything, thank you for the insight! o/

JP wikia says you go grinding Daiku Cave on hard for basic-class mags... If you're over lvl10 that's a tall order to go back into but meh.
