Bone Protrusion

The power to jut out bone spears from one’s body.

Capability
The user can eject the bones quickly to impale intimately close people. There is an organ tunnel for the bones to travel through coated with lubricated mucus.

The bone spears retract back into the bone, the skin sealing over. Can forcibly eject bone spears out of body to impale something, but this results in temporally disuse of power as the bones juts need to grow back (needs calcium).
