The Way of the Shadow Palm is the way for the ones who don't fear the shadows and all of it's powers. They spend years mastering how to control the dark energy from Shadow Fell and use it as a weapon against it's enemy, while the monk can ignore any kind of defenses, all of this while sacrificing his vital energy. Temples of the Way of the Shadow Palm are extremely rare as it's viewed as a taboo in the Forgotten realms, since the power to control the shadows often corrupt the monks, however most remain true in fighting against the forces of evil, after all, fight fire with fire. 

Shadow Palm

Starting when you choose this tradition at 3rd level dark tattoos start to appear around your body to help you use the power from the shadows. Whenever you hit with one of your unarmed strikes you can choose to use one point from your ki point's and deal two extra dies of your actual martial arts die as necrotic damage against the target you hit. At 8th level you roll one additional die, at 13th level you roll one more additional die. The point of Ki required to use this feature also increases by one when you reach the 10th level.
