Wyrm-Born Sorcery (Metamagic)

Your draconic ancestry allows you to enhance your spells with the power of dragons.

Prerequisite: Draconic bloodline sorcerer or dragon creature type

Benefit: A number of times per day equal to 1 + your Charisma modifier you can change the energy type of a spell you cast to the energy type associated with your draconic ancestry. You also deal an additional +1d6 points of damage of that energy type per spell level upon a failed saving throw. A draconic sorcery spell uses up a spell slot equal to that spell’s actual level, and does not adjust the casting time of that spell.
