Is there a way to remove crystal affix the cyan colored? I tried using kyanite but it won’t. I guess the only way is using quartz? If that so, I just wasted my pandemoneum robe. I used obsidian crystal and all choices are trash so I just choose 2k++ mp regen. I thought I can just replace it in the future when I have another obsidian cs. :(persevere:
Yes, there is a way. Disenchant. Quartz.
Though in the process you remove everything else in the item since disenchant removes affixes from bottom to top, and crystal affix is topmost, so… 
dammit! it should be the other way around. T__T
owh… i thought quartz “randomly remove one affix” lol… that bummer
