Range Long (400 ft + 40ft/level)
Target One structure
Duration 60 days
This spell creates a powerufl set of protective wards that operate on a single fortified building, temple complex, tower, or similar structure. These wards protect the physical integrity of the structure and prevent magical access.
A building protected by Preservation suffers only 25% of normal structural damage from sources such as siege engine, earthquakes (natural and magical), and powerufl weather-affecting spells. Spell which directly affect the physical integrity of the strucutre (Passwall, Stone Shape, Transmute Rock To Mud, etc.) simply fail when casy on the protected building.
Preservation creates a permanent magical ward on the structure that acts as either Protection From Evil, Protection From Good, Protection From Law, or Protection from Chaos. The caster can decide which to have at the time of casting. There are two wards that overlap, one with respect to Good vs. Evil and the other Law vs. Chaos. Bonuses to saving throws do not stack, but the ward is equally effective against the respective alignments.
Magical spells allowing access to the building also fail. Thus, creatures attempting to Teleport or Fly into the building are stopped. Birds and creatures with natural flight may enter the building normally, as can the caster using his own magical means such as teleporting. When a cleric casts this spell, all clerics dedicated to the same deity, not necessary sharing the same Domains, benefit from a Sanctuary spell.
The spell ends in 60 days if the structure is destroyed.This spell was originally from the 2e Tome of Magic
