Magic Power Attack [Sorcery]

Prerequisite: Charisma 15, Magic Attack Bonus +4

Benefit: Whenever casting a spell which requires you to make a magic attack roll, you may use up additional Magic Points to gain bonuses to your magic attack roll. For every 2 MP you expend in this way, you gain a +1 to your Magic Attack Bonus, to a maximum additional bonus equal to your Charisma modifier. Furthermore, for every 2 MP you expend in this way when casting spells that affect only creatures of a limited number of hit dice, that number is increased by +1.
