Critical hits with this weapon to targets of evil alignment deal and extra 3d6 good damage for a x2 multiplier, 4d6 for a x3 multiplier, and 5d6 for a x4 multiplier. Additionally, if you roll a natural 20 when attacking and confirm the critical hit, the weapon blasts your target, doing 4d6 more good damage to any enemy of non-good alignment.
