What crystal to use?

[Golem]

Obsidian gives 3-6 random Crystal Affixes to choose from. if used again, it has a chance to hopefully increase to Crystal affixes value to maximum.

Kyanite only works on Normal (yellow), Epic (orange), Legend (Red), Set (Green) affixes, and only 1 at a time.

Quartz can be used to take off multiple affixes, but it is random and can end up ruining a good item if it takes off an affix you don’t want taken off.

for Eternal Items and what Crystals can be used on them…

Bad luck? Crystal affix weaker than epic affix

for the HP & MP on hit, Crystal only doubles instead of triple, so same value as Epic on Eternal Item. from +250 to +500 instead of +750. I think there is a game balancing reason for this. Edit: also, Obsidian can be used to improve your Crystal Affix now, not just Diamond. and only a few Crystals can be used on Eternal Items.
