Spell Specialization

Choose one spell that belongs to a school in which you have Spell Focus. Your caster level is 2 levels higher when casting that spell. This change affects all variables associated with caster level, including level- dependent variables (such as range or damage), and dispel and spell penetration checks. In addition, when you prepare that spell with a metamagic feat, it takes up a spell slot one level lower than normal, to a minimum of its normal level. For example, if Leanine Starborn takes Spell Specialization and chooses frost nova (a 3rd-level spell), she can prepare a maximized frost nova as a 5th-level spell, a silent frost nova as a 3rd-level spell, and so on.
