thats a damn good robe for fire expansion :v
And AB as well... not as good, though. And it's decent for CC, so it can be a good robe for geneticists.
I see, thats so unfortunate. It will take 30 tokens per attempt(assuming it fails to get the optimal). You will need 300 tokens to enchant/reset it for merely 10 times, and thats far not enough to get you the desired result. To get Int3/Int3, or even Int2/Int2, you will likely need at least 3000 tokens.
I didn't even use a lot of tokens to get this enchant, but then, when I get something really good, there's always some trolling from fate.
