Undead entering the area of effect were subjected to turning as if by a cleric two ranks lower than the caster of this spell. The turning was subject to the normal limitations of that power, i.e., limits on how many undead can be turned at once. Any undead that failed to be turned ignored undead ward for the duration of the spell. Likewise, any undead already within the barrier set up by this spell were not affected unless they exited and attempted to reenter. Note that the casting priest did not need to have the ability to turn undead.
