Raw Quartz is also unobtainable because there's no more nether right? Unless you're trading with someone you can't get it anymore right?
Raw Quartz is the same "rarer than the finished product" deal if things are still the same as when I had some.
My first beacon set me back 15 hard earned diamonds, it was griefed with no logs and between them, noobcrew and cypriotmerks helped refund me. Good old skyblock. Also Gravel/Flint General Abuse/Mass Greifing Ability to find other portals and greif other islands.
I don't remember but I'm pretty sure I wasn't there when there was the nether. I quit for a while probz why Was griefing in the nether allowed?
