My son and I was exploring the sunken BMV Ararat and weird things were occurring. I was fighting a Hydra with a Rising Colossus. He was off screen and cast a Rising Colossus to help. As soon as he cast, something instantly killed him. The Hydra was not close to him, nor was it declared on him. He was not hit with any spells either, just instant death. He has 140 hit points and single hits do not kill him, but what ever this was dealt instant death. The other weird thing is we would get the message that we didn't have the required regents to cast the Raising Colossus sometimes, and other times we could cast it with no problems. We both had plenty of the required regents on us. This was the first time either of us had been down there, so we didn't know what to expect, but this was really weird. Anyone experience anything like this?
