Spellcasting Master (Ex)

At 9th level, a Pathfinder savant can focus his mind three times per day as a swift action. Once he’s focused in this way, any spells he casts for the remainder of that round do not provoke attacks of opportunity. Spells with a duration of concentration that he casts in this round persist for a number of rounds after the Pathfinder savant ceases concentrating equal to his Intelligence, Wisdom, or Charisma modifier (whichever is highest).
