who needs to kill magnus?

It's fake. The name of the item is oh so strangely farrrrrr more blurry than the rest of the entire screenshot. It's not in the game's data.

Either fake or from a private server.

While it is most likely fake, the fact that the name is blurry is not really an indicator. That happens all the time when you take a screenshot ingame with Scroll Lock on any item with a pink name.

There are several pictures like that in the "Godly Scrolled Items" thread.
