The Drow Judicator is a special prestige class of the drow. Servants of demigod Selvetarm, to whom they must make an unholy pledge, judicators are spellcasters that have survived the vicious rites necessary to work with demons and Lolth-warped spiders. They often serve, albeit grudgingly, high-ranking priestesses of Lolth as defenders and assassins. While at least some schooling in spellcasting is required for a drow to become a judicator, only the toughest and meanest sorcerers and wizards can survive the entry requirements.
