Alter Self (Bloodline)

Natural Weapons. You grow claws (Slashing), fangs (Piercing), horns (Piercing), and/or hooves (Bludgeoning). When you use your Unarmed Strike to deal damage with that new growth, it deals 2d6 magical damage of the type in parentheses instead of dealing the normal damage for your Unarmed Strike, and you use your spellcasting ability modifier for the attack and damage rolls rather than using Strength. You sprout wing of your ancestrial background (dragon/celestial/fiend/or demon). You gain a fly speed of 60 feet. You also gain a resistance to damage based on bloodline. 

Higher Spell Cast: You gain 1d6 damage for every spell slot higher than 2nd.
