DISGUISE SPELL [Bard, Metamagic]

You can cast spells without observers noticing.

Prerequisites: Bardic music ability, 12+ ranks in Perform.

Benefit: You have mastered the art of casting spells unobtrusively, mingling verbal and somatic components into your performances so skillfully that others rarely catch you in the act.  Like a silent, stilled spell, a disguised spell can't be identified through a Spellcraft check.  Your performance is obvious to everyone in the vicinity, but the fact that you are casting a spell isn't.  Unless the spell visibly emanates from you or observers have some other means of determining its source, they don't know where the effect came from.  A disguised spell uses up a spell slot one level higher than the spell's actual level.
