Spear. All attacks made with this weapon has the Lightning Attacks special rule. On the round that the wielder of the Lightning Spear charges, for each successful Wound made with this weapon the spear strikes the model behind the hit model with an attack at -1 Strength. If this attack wounds, then the model behind the second wounded model is struck with an attack at an additional -1 Strength. This will continue until you fail to wound a model.
