You can use the power of your bloodline to surround yourself in its element.

Prerequisite(s): Cha 13; draconic or elemental bloodline.

Benefit: Once per day, you can surround yourself with the element associated with your bloodline. For a number of rounds equal to your Charisma modifier (minimum 1), you gain resistance 5 to that energy type, and all creatures that attempt a natural weapon attack or an unarmed strike against you take 2 points of damage of that same energy type. If you already have resistance to that energy type, the resistance increases by 5.

Special: You can take this feat multiple times. Each time you do, you gain an additional daily use of this feat.
