Prayers of SigmarURL Copied!
Once per magic phase, a Priest of Sigmar is allowed to use prayers from the Prayers of Sigmar list opposite. An Arch Lector may use two different prayers per turn and a Warrior Priest may use one. Prayers are cast exactly like bound spells with a power level of 4. Unless differently stated in their description, they can be cast on the Priest himself or on any one character or unit champion within 12" of the Priest.
Hammer of Sigmar: The model can re-roll failed rolls to hit and wound. Remains in play.
Armour of Contempt: The model gets a 4+ ward save. Remains in play.
Healing Hand: The model is immediately healed of all the wounds it has suffered during the battle up to that moment.
Unbending Righteousness: Can only be cast on the Priest himself. The Priest and any unit he joins is Unbreakable. If the Priest leaves the unit or is slain, the prayer will immediately cease to affect the unit. Remains in play.
Soulfire: Can only be cast on the Priest himself. All enemy units in base contact with the Priest suffer D6 Strength 4 hits with no armour saves allowed. Undead, Daemon or Forest Spirit units suffer D6 Strength 5 hits with no armour saves allowed.
