Unless you did your knowledge, the first knowledge level iirc quadrouples our knowledge %, and it continues to go up significantly per rank. I personally don't have the patience to test it out on the PTR as free labor just to do it again on my actual toons. Really though there's not a lot of ways it could go without it being a negative thing. Gold traits are typically 3-4% dmg increase, and this is worded as an RNG rift that gets added to the pool. There's lots of different ways you can go about it, but none of them are what people have been asking for.
