Wrathbringer

Helmet gives its weilder a sence of unholy authority.
Helmet: Epic Rulership over Melekus worshipers
The wielder can command the obedience and fealty of evil creatures within 360 feet when he or she activates the device (a standard action). Creatures totaling 900 Hit Dice can be ruled, but creatures with Intelligence scores of 17 or higher are entitled to a Will saving throw (DC 29) to negate the effect. Ruled creatures obey the wielder as if he or she were their absolute sovereign. Still, if the wielder gives a command that is contrary to the nature of the creatures commanded, the magic is broken. The rod can be used for 1,500 total minutes within a 24/hr period. This duration need not be continuous.
