This specific illusion is one that, surprisingly, has beneficial effects to the victim. Although this depends on the context used. By making contact with an individual, or simply having influence over their chakra network through a prompt, the user may remove the sensation of pain from the victim of a wound of some sort. This can be used to assist in medical procedures, or more deviously, be used as a means to disallow any reaction to a strike that has occurred. This in turn, can cause individuals to not react to wounds, and therefore, die of symptoms such as blood loss, and the like. However, if one sees the wound, then the technique immediately dissolves, as the visual sensation of seeing the wound would cause the body to produce "pain" to alert the victim.
