Blade charge
(Rule)Description: Once per battle, a unit that includes any models with weapons with this special rule may declare a Blade Charge at the start of any of the controlling player’s Assault phases. For the duration of that Phase, the attacks made by all models in the unit with weapons with the Blade Charge special rule gain the Rending (3+) special rule in addition to any other effects their weapons might have. This does not replace or improve any other versions of the Rending (X) special rule already possessed by the unit.
