I think there should be a little more risk to rolling a rook. -50 mood is much too cheap for high-level players. After all, players who are trying to roll rooks are summoning the ancient enemy of the Giants and all of Ur! A rolled rook should immediately stun the player who summoned him. The rooked player starts losing energy and mood and can't move, eat, drink, or do anything other than chat to request help. If he isn't revived in time by enough other Glitches, he dies and goes to hell for a round of grape-squashing.
