Components: V, S, M
Duration: 1 turn/level
Casting Time: 1 round
Area of Effect: Creature touched
Saving Throw: None

By means of this spell, the priest renders a creature touched immune to the effects of a specified spell of 4th level or lower. It protects against spells, spell-like effects of magical items, and innate spell-like abilities of creatures. It does not protect against breath weapons or gaze attacks of any type. The spell has additional limitations. First, the caster must have directly experienced the effect of the spell specified. For example, if the caster has been attacked by a fireball spell at some time, then he can use spell immunity to provide protection from a fireball. Second, the spell cannot affect a creature already magically protected by a potion, protective spell, ring, or other device. Third, only a particular spell can be protected against, not a certain sphere of spells or a group of spells that are similar in effect; thus, a creature given immunity to the lightning bolt spell is still vulnerable to a shocking grasp spell.

The material component for spell immunity is the same as that for the spell to be protected against.
