Sudden Action (Su)

Benefit(s): The ninja has learned to act with such surprising suddenness that her foes cannot react to any opening or distraction the ninja may suffer by her actions. The ninja does not provoke attacks of opportunity when she casts a spell with a casting time of 1 standard action or less, makes a ranged attack with a thrown weapon, or moves out of her first square during a move action. Each use of this ability uses up 1 ki point.
