Honestly focusing on anything to help you with gems would be most beneficial since if you're f2p getting everything you need for those is borderline impossible. As for evo stones, it depends what you're doing with them. Are you making oil/sacred vial? If so I'd just buy that when it's available. If you craft it yourself you'll run out of demon spirit in no time with the amount of vials you'll need. And lastly, you're going to need gold if you don't get enough of all you need on your own.

Aww I want 8K NC D: I've never been able to buy any
