Double Charge Damage (Quality)

While on a mount and wielding a weapon with the Double Charge Damage quality, the weapon's base damage dice are doubled, and any damage adders due to high strength, feats, and weapon enhancement bonuses are also doubled. If the charge attack critically hits, the critical hit is treated as if the crit multiplier were two higher than normal for the weapon (this is instead of, not in addition to, the doubling of the weapon's base weapon damage).
