Lash whips are living ropes of muscle and sinew which writhe and twist with a will of their own. In combat they strangle and bind, entangling creatures so that they are easy meat for the Tyranids.
All enemy models which are in base contact with one or more creatures equipped with lash whips reduce their number of Attacks by 1, to a minimum of 1. Lash whips may not be used by creatures who are 2" away and using the Leaping special rule to count their full number of Attacks.
