This ability can be used to manipulate joints and tendons in a variety of ways. It is possible to increase or decrease a person's flexibility and joint strength, and to control movements to some extent, similar to puppetry. It can thus be used offensively to contort a person's body into unnatural and painful positions, to force a person to do something or simply to regain control of one's own limbs when manipulated by another ability. It can also be used to inflict and to heal afflictions of the tendons and joints, such as arthritis, tendinitis or neck and back aches and stiffness.
