This is not a complaint, it's a notification. Lord Nightshade cheats. He'll cast doom and gloom, I'm not kidding, he really does. He can also cast spells when it isn't his turn.
You're referring to Lord Nightshade in Stormdrain Tower in the Haunted Cave off Triton Avenue?
I've helped a wizard farm Lord Nightshade. We must have fought him 40 times, and I've fought him at least two-dozen times on my various wizards. I've never seen him use Doom and Gloom or cast when it wasn't his turn.
