Undead Ward
(Abjuration, Necromancy)(Wards)

Range: Special
Components: V, S, M
Duration: 1 turn/level
Casting Time: 2 turns
Area of Effect: 5-foot cube/level
Saving Throw: None

 This spell prevents most types of undead creatures from entering the area of effect (a cube whose sides equal the caster s level times 5 feet-a 15th-level caster could affect a cube whose sides equal 75 feet) .
 When an undead creature attempts to enter the protected area, the creature is affected by the ward as if it were being turned by a priest two levels lower than the caster. The casting priest need not have the ability to turn undead himself.
 Thus, an undead ward created by a 10th-level priest would turn creatures as if by an 8th-level priest .
 The results of the turning attempt are calculated normally. If a large number of undead assault the warded area, not all of them are turned by the spell, since the normal limitations apply Undead who are unaffected by the turning attempt ignore the undead ward for its duration.
 Undead within the area of effect when the spell is cast are not affected. However, when such undead leave the area of effect, they are subject to the effects of the spell if they attempt to reenter.
 The material component is the priest's holy symbol, which must be carried around the perimeter of the area to be warded.
