Whipsting
this was a form of weapon used by the Shaper caste of the Yuuzhan Vong. Like most other Shaper implements, the whipsting was a modified lifeform which was grown to serve this one purpose. It was essentially a long cord which was coiled inside a sac in the Shaper's hand. When poked or nudged in the right place, the living cord would eject its mass outward at a target. The end of the cord was tipped with a poisonous spine, which could pierce fleshand deliver a deadly injection. When jerked free, the whipsting recoiled into its sac to replenish its poison supply for its next use.
