Why are crystals still a thing?

[Jonsky]

I'm also not a fan of the number of bicolor gemstones needed. I have to spend all day farming fates then the gemstones are gone in a heartbeat. Feels more like work than fun.

You can send out a combat job retainer to hunt for the materials that you are spending bicolour gemstones on. Depending on their item level, they can get you 5-15 pieces of a material every hour.
