the Judge gear is pretty bad by today's ilvl standards
Word of former GMs is that each piece has some sort of hidden effect. Like the cape would give you a permanent brew effect while equipped, the sword has 100% endeath, etc.
But they're also GMs and have access to plenty of debug commands, they don't need to rely on gear.
I really like this, I used to be fascinated by GMs when I was younger, the "in-universe" part of them being these shadowy arbiters of the world's strongest, keeping them in check when nobody else could, was cool as heck to me, and I consumed any and all information I could find about them, had never heard their gear had hidden effects! Really wish there was more info out there about what GM characters are capable of.
Back on the topic, a guy did manage to record a couple of the GMs absolutely curb-stomping Omega, but there's not much to really see, they rock up, flap around a bit (clearly struggling with having flee speed active in combat lol) and it immediately dies.
GMs appear around 10:56 in the
video, which won't embed for some reason, probably because it's a VOD or something.
