Flickering, yellow chaotic energy surrounds you. This energy has three effects.

First, you gain a +4 deflection bonus to AC against attacks by lawful creatures.

Second, on making a successful melee touch attack against an lawful creature from another plane, you can choose to drive that creature back to its home plane. The creature can negate the effects with a successful Will save (spell resistance applies). This use discharges and ends the spell.

Third, with a touch you can automatically dispel any one enchantment spell cast by an lawful creature or any one lawful spell. Spells that can't be dispelled by dispel magic also can't be dispelled by dispel law. Saving throws and spell resistance do not apply to this effect. This use discharges and ends the spell.
