It seems to be a knight running two accounts with his priest. The devs might want to look into whichever accounts these two chars are in. The knight suddenly turned invisible and I know he's the one because I had added him before and he turned on his hack.
He gets buffed by his priest, lures the aleph, and aoes them like any other aoe knight, except he's invisible. Never seen this kind of hack before. And this is happening right now, at the time of this post. I have half a dozen screen shots as proof, but it says I don't have permission to upload attachments. Anyways, thanks and hope you guys get this hacker, whoever it is.
