Quick preview video of the warlock level 75 ability, Shadowflame. I didn't get as many good clips as I would've liked to, but I think this does a very good job of showing off the new ability for those unable to see it in action.
In Flames - Free Fall
I highly recommend the higher resolution version if you're big into quality like I am. Looks much better, though a larger file size.
