Undead ward

Undead ward was a necromantic abjuration spell that created a barrier that turned undead like the cleric ability.

Effects
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 are not affected unless they leave and attempt to reenter. Note that the casting priest does not need to have the ability to turn undead.

Components
The caster must walk the perimeter of the area to be warded, speaking the words of the spell and using his or her holy symbol.
