I'm about to choose my artifact for my feral druid. I know that I should choose  fangs of Ashamane but the weapon isn't a option. 
Why can't I choose it?
Or more like I can't do the artifact quest for feral

Hi,
I have a question to the Dimensional Rift.
How does it works behind the scenes?
I know already it doesn't work with Havoc but is it scalable with other effects like Eradication or Intpot?
I think not because the weapon casts it and not the char but am I right?
After theoriecrafting my head is booming and actually I'm confused xD
