Not that rare, more like uncommon. I got double UV's on my Gigawatt pulsar. The current idea is that chances for 1 UV are 1 out of 10, chances of 2 UV's are 1 out of 100, chances of 3 UV's is 1 out of 1000.

I've gone days and days without any UVs. I've never crafted an item with more than one, and even when I crafted items with a single UV, it was back when that was the most you could get.

"I crafted a swift flourish it had 3 UVs a med damage vs constructs one for low on fiends and one for low on jellies I think sold it for 60k on the AH"

I think I sould say...

ONLY!!!!!!!!!!!????????????

Iactually have no real idea about how much its worth, but I'd imagine much more than 60k.

I don't... think that the rate for 2 UVs and 3 UVs works like that... I don't know... IMO... I think it'd make more sense if we just said there's a 10 % chance of getting a UV, and in that 10% there's like... a 50% chance to get 1 UV, 30% chance to get 2 UVs, and 20% chance to get 3 UVs... I know that this isn't the actual percent... and probably not even close... but they're just random numbers.

So ... from what I just said... (just pretend with me, guys. lol) it'd be:
5%chance to get 1 UV
-or-
3%chance to get 2 UVs
-or-
2%chance to get 3 UVs
-or-
90%chance to get nothing.

That was actually a bad deal for the buyer, he got pretty lucky. Med vs. Constructs, the Flourish sucks vs construct. Low vs fiend, yeah that could be very nice, but that's a low only.. Low vs. Slime, Flourish sucks vs slime. So, in short the only decent UV could be fiend one, but that's low. I imagine the only reason it sold for 60K was because it was a triple.
