When this spell is cast, it creates a magical barrier around the recipient at a distance of 1 foot. The barrier moves with the recipient and has three major effects:

First, all attacks made by evil or evilly enchanted creatures against the protected creature receive a penalty of -2 to each attack roll, and any saving throws caused by such attacks are made by protecting creature with a +2 bonus.

Second, any attempt to exercise mental control over the protected creature (if, for example, it had been charmed by a vampire) or to invade and take over its mind (as by a ghost magic jar attack) is blocked by this spell. Note that the protection does not prevent the vampires charm itself, nor end it, but it does prevent the vampire from exercising control through the barrier. Likewise, an outside life force is merely kept out, and would not be expelled if in place before the protection was cast.

Third, the spell prevents bodily contact by creatures of an extra planar or conjured nature (such as aerial servants, elementals, imps, invisible stalkers, salamanders, water weirds, corn, and others). This causes the natural (body) weapon attacks of such creatures to fail and the creature to recoil if such attacks require touching the protected creature. Animals or monsters summoned or conjured by spells or similar magic are likewise hedged from the character. This protection ends if the protected character makes a melee attack against or tries to force the barrier against the blocked creature.

To complete this spell, the priest uses holy water or burning incense.

This spell can be reversed to become protection from good; the second and third benefits remain unchanged.

The material components for the reverse are a circle of unholy water or smoldering dung.
