So me and a couple of friends were replaying the Vault of Glass raid, which we have already completed a couple of times. When we got to the Gorgon Maze someone suggested that we could try to kill one of them, just for a laugh. Low and behold it's possible to kill the Gorgons. Everyone used their Supers, Grenades and most of us used exotic weapons. The Gorgon was actually rather easy to kill, and upon killing it, we received Grimoire process. Also, it's worth noting that killing a Gorgon cancels "Gorgons Gaze", therefore enabling players to continue throughout the maze. Anyway, looks like me and my friends were some of the first to discover this, so I thought I'd share it with the community!
