[Zooko]

What good is a doomsday device if you don't TELL anyone!?

My shiny new deterrent is the spell "Doom". As far as I can tell, it is impossible for any attacker to avoid being cursed if he attacks my territory. So don't try it!

Also, my diligent national defense mages are practicing up on the spells of Blindness, Seven Year Fever, and Horror Mark.
