The Painrial, a diminishing fabrial, is used to decrease pain felt by someone.
Artifabrian, Navani, aided in the design of the painrial. It had a set of clawlike legs which were wrapped around the painful area and locked in place. She believes it has lot of potential, for example on the battlefield to dull the pain of wounded soldiers, or allow surgeons to work on patients without worrying about their pain. She notes that although it could be very useful, it does not heal; it only diminishes the feeling of pain.
