Protection From Lightning

If the caster touches themself, this spell grants temporary immunity to lightning or electrical effects (normal and magic). When the spell absorbs 12 points per caster level of magical lightning damage, it is discharged. Otherwise the spell lasts for 1 turn per caster level. If the spell is cast upon another creature than the caster, protection from lightning grants temporary immunity against normal lightning or electrical effects. The spell also offers a +4 bonus to saving throws against magical lightning and if the save is successful, the creature suffers no damage (and only 25% if the save fails). This version of the spell lasts for 1 turn per caster level.
