Your mastery of illusions allows you to subtly alter your appearance at whim.
Prerequisite: Ability to cast 3rd-level spells.
Benefit: As long as you have a glamer spell of 3rd level or higher available to cast, you can alter your appearance as the spell disguise self, except that the duration lasts 1 minute per level of the glamer spell.
This illusory transformation requires a full-round action to activate.
As a secondary benefit, you gain a +1 competence bonus to your caster level when casting glamer spells.
