So I recently learned about UVs, and set out to get some nice ones on my gear. Already crafted a Calibur ASI High. But now, I'm trying to get a Sentenza or Biohazard to fill my shadow damage needs, and I notice both the Antigua and Catalyzers are uncraftable. So, I assume I can buy one with tokens, and then go to one of the gremlin smiths to throw some UVs on it?
What strategy do people usually go for? Take the 20k 1-variant service and repeat until you get an UV you need? Go for 3-variant and settle for what it gives you because more is better? I'm still pretty poor in this game and I don't feel like wasting my crowns without knowing beforehand what is generally considered the wisest investment.
The cheapest option (unless you are super lucky) is to buy what you want from the AH or bazaar. I mean, I've spent thousands of ME crafting wolver caps, and I ended up buying a shock high wolver cap and only ever crafted one fire high wolver coat. The rest were either things I didn't want (Curse/poison Max!) or where med/low. Your odds of rolling or crafting are incredibly low if you are looking for a specific UV.
If you have a paid account (or elevator pass) then you can use free mist to craft an umbra driver, since that would be a good option for shadow damage and the cheapest way to get a UV, but you might be waiting for a long time.
