Lets kill this guy, or if you afraid to kill him at least knock him unconscious. Each round he gets a better chance at summoning the apocalypse, grabbing and yelling at him isn't going to stop him if people actively trying to kill him hasn't already persuaded him to do so. I would hate to lose this campaign because we decided to try and think outside the box at the last minute when the obvious answer to stop the guy is right their before us. If he's dead or unconscious he ain't summoning in the the apocalypse.
I hear you loud, clear and on FM, as Cat used to say. Let's hope my dice agree
