Cloaked Casting [Skill]

Sleight of hand can conceal spells as well as theft.
Prerequisites: Spellcasting track, Larceny as a trained skill
Benefit: When casting a spell, you can make a Larceny check as a free action to conceal your work. Opponents whose Awareness defenses are equal to or less than your check result are unaware that you are the caster of the spell. In addition, you may make a Larceny check in place of a Perception check for the in-combat use of the Perception skill. You gain a +2 feat bonus to Larceny checks.
