In each Magic phase, the Priest can use one of the following Prayers, counting it as a Bound Spell with a Power Level of 3. Ar-Ulric's fervour and will-power is such that he may use two Prayers in every Magic phase, although he may only use each Prayer once successfully:
Battle Howl
Remains in play until dispelled or the Priest attempts to use another Prayer. As long as the Battle Howl is in effect, the Priest and any unit he leads add D3" to their charge moves. If the charge is failed, the extra movement is wasted; make a normal move towards the target as normal.
Destruction
Every enemy model in base contact with the Priest suffers a single Strength 4 hit.
Winter's Chill
Any units engaged in close combat with the Priest or the unit he is with must take a Leadership test. If failed, they suffer a -1 penalty to hit in the next Close Combat phase. Note that this is not a psychology test.
Fury of Ulric
Remains in play until dispelled or the Priest attempts to use another Prayer. The Priest and any unit he leads become immune to fear, terror and panic.
