"Magic Pain Glove"

The Pain Glove is a device of arcane technology used  as a tool for education, meditation, penance, punishment and even torture. This bulky machinery takes the form of a large cylinder in which hangs a body glove made of electro-fibres. The suit will cause pain to anyone who wears it by using electrical pulses to stimulate the nerve endings of their skin.

Settings

 * Educational: The lowest setting, and the only one that can be used on normal humans without death or severe injury occuring.
 * Meditational: A low to moderate setting, typically used as the form of "Educational" for Astartes. At this level, the pain often becomes unbearable and concentration often impossible.
 * Penance/Punishment: A moderate to high setting, typically used for the sake of dealing pain, without death, Some Astartes are known for using this setting as a way to "recover" from self-failure
 * Torture - This is the highest setting of the Pain Glove and is only administered to captured Traitors, Heretics, or Xenos to break them and force them to confess or deliver information. This setting requires careful monitoring by an experienced interrogator, for it can quickly prove lethal even to an Astartes.
