No armour saves are allowed for Wounds caused by the Slayer of Kings. In addition, Archaon may unleash the power U'zuhl in any Close Combat phase. If he does this, he fights with double his normal number of Attacks (to a maximum of 10) but any rolls To Hit of a 1 will strike either himself or a friendly model in base contact (controlling player's choice). Archaon may not re-roll To Hit results of a 1 when unleashing U'zuhl. Once U'zuhl is unleashed, Archaon must use this special ability in every close combat he is subsequently involved in for the rest of the battle.
