Monks of the Way of the Thousand Needles learn to directly influence their body and that of others with ancient medical techniques. The Way of the Thousand Needles owes its name to its practitioners making use of small, sharp tools to tap into the inner-most physical layer of all beings, though these are not always necessary for their craft.  These monks are able to use this knowledge to grant better health and treating unwellness or causing severe damage to a creature's motor functions, which of these is largely up to their own ends and the moral teachings passed down in their monasteries.
