Spell resistance (SR) is a special defensive ability. If your spell is being resisted by a creature with spell resistance, you must make a caster level check that is at least equal to the creatureâ€™s spell resistance for the spell to affect that creature. The defenderâ€™s spell resistance is like an Armor Class against magical attacks.
