The piercing bolt spell allows you to hurl a single missile of force energy that has two effects. You make a single ranged touch attack when casting piercing bolt, if you succeed, you automatically dispel all abjuration spells protecting the target and all protective spells that have the force descriptor (such as mage armor or shield) of 3rd level or less. It even suppresses bracers of armor and rings of protection for 1d4+1 rounds. You also cause 1d8 points of damage per two caster levels (maximum 5d8).
