Weapons crafted of Ithilmar are incredibly lightweight and balanced to perfection. Such blades slice swiftly through the clumsy parries and counter-thrusts of enemies.
When engaged in combat, a model with this special rule that is fighting with a hand weapon may re-roll any rolls To Hit of a natural 1.
Note that this special rule only applies to a single, non-magical hand weapon and does not apply to a model’s mount (should it have one). If the model is using two hand weapons or any other sort of weapon, this special rule ceases to apply.
