Armour saves cannot be taken against Wounds caused by the Spirit Sword. Furthermore, immediately when an enemy character, champion or monster suffers one or more unsaved Wounds from the Spirit Sword, both he and the wielder must roll 2D6 and add their respective Leadership values.
If the wounded model’s total is higher, or the totals are the same, nothing else happens.
If the wounded model’s total is lower, it immediately suffers a Wound for each point by which its total was exceeded, with no armour saves allowed.
