Spell Immunity

By means of this spell, the cleric or any creature touched is made immune to the effects of a specified spell of 4th level or lower that the cleric has directly experienced. 

For instance, if the cleric has been hit by a fireball spell at some time, then this spell can be used to protect someone from the effect of a fireball. 

This spell cannot affect an intended recipient who is already magically protected by a spell or other temporary effect. 

The magic of this spell will only protect against actual cast spells, not against effects of magic items or a creature's innate spell-like abilities, but immunity lasts for the full duration of the spell. Only one spell immunity can be in effect upon a single creature at one time; any applications subsequent to the first have no effect until the first duration ends. The spell immunity does not extend to items carried by the recipient, which must still make saving throws (if applicable) to avoid damage. Only a particular spell can be protected against, not a certain class of spells or a group of spells which are similar in effect; thus, someone given immunity from lightning bolt spells would still be vulnerable to a shocking grasp. 

The material component for spell immunity is the same (if any) as for the spell to be protected against.
