Order of the Rack

Order of the Rack Hellknights hate wastefulness of both thought and deed. They crush pointless dreams, end rebellions, and trample frivolous or dangerous inventions. They also closely observe individuals, seeking hints of destructive ambitions and wasteful vices, and are skilled at destroying seditious writing and strange inventions. Three times per day as a standard action you can target a single creature. That creature must pass a Will saving throw (DC 10 + level in this prestige class + your Charisma bonus) or become unable to cast spells for a number of rounds equal to caster level in this prestige class. At 5th and 9th levels you gain one additional use of this ability. The same effect occurs whenever you confirm a critical hit.
