You develop natural weapons like those of your draconic ancestors.
Prerequisite: Draconic Heritage, sorcerer level 1st.
Benefit: You gain a claw attack. You can make a natural attack with two claws, dealing damage based on your size as if you were truly a dragon (Small 1d4, Medium 1d6, Large 1d8). In any round when you cast a spell with a casting time of 1 standard action, you can make a single claw attack at your full attack bonus as a swift action against an opponent you threaten.
