Jsk Feats:Spell Slinger

You have spent time to practice the art of rapidly casting lesser spells. You gain the following benefits:
 * Increase your Intelligence, Wisdom, or Charisma by 1, to a maximum of 20.
 * When a cantrip that requires a spell attack roll would increase the number of damage dice rolled at 5th, 11th, and 17th level, you can choose to make an additional spell attack roll instead of increasing the damage dice. You cannot mix and match these alternative methods of casting: when you cast a cantrip, you choose to increase the damage dice or make additional attacks, not both. You make this decision when you cast the cantrip, but before any dice are rolled.
