It sounds like its achieved in a different way, but yes, voldemort was a bug where all of a boff's abilities were unlocked when you equipped them. It's one more bug that cryptic has had the lack of ability to squash. I'm assuming its something locked deep in the coding that they can't seem to figure out or root out

There was a guy running around in a defiant a couple of months ago with EWP3, so the original bug is still around as well as this new horcrux
