I was told you can redo quests for xtals I've been trying but it won't give me end bonuses. Do I have up finish all of them first? Or what? Ty for help.
The devs removed the xtal bonuses at the end of quest blocks due to player abuse. You can still get random xtal drops I believe, but the rate is ridiculously low. The stat near the top of the guide is about two years old, so it's not reliable but probably a reasonable estimation still.
Clarify, removed the bonuses for subsequent resets after achieving them one time. you can still get them the first run through or the first time you complete a certain quest (as in, if you got halfway through and then reset, you could still get bonuses from the second half. Just not the first.)
