Protection from evil provides good protection against evil fiends and somewhat minor protection against undeads. When successfully cast target is surrounded with invisible layer of holy force. Duration and strength of the aura depends on casters abilities. The more evil the attacker is the better cover is provided. The duration and power of the protection are based on caster's wisdom and alignment. Mastery of shielding and a good relic are required for best protection. The protective aura can be boosted by sprinkles of holy water. Old nuns with high purity of heart are known to be able to enhance the protection thus giving shelter against other evil actions.
