Dark monk (3.5e Alternate Class Feature)
From D&D Wiki
Orcs set up monasteries to get closer to their god of war so they could train in combat, rather than meditation. Quickly, these dark monks became capable of producing pitch black chi. This strengthened them, enchanted their weapons, and allowed them to make pitch black chi blasts. Many races, good and evil, began training as dark monks. Dark Monks typically work alone, just as a single assassin works most efficiently. They usually wear black hoods, and their resourcefulness makes them some of the most deadly assassins there are.
