Infernal Bloodline (Bloodrager)

At 1st level, as a swift action up to three times a day you can infuse your attacks with hellfire. When you do, your melee attacks gain the flaming weapon special ability for 1 round. At 12th level, you can use this ability five times per day, and the effect is treated as flaming burst.

At 4th level, you gain fire resistance 5, as well as a +2 bonus on saving throws against poison. At 8th level, your fire resistance increases to 10, and the bonus on saving throws against poison increases to +4.

At 8th level, you gain a +4 bonus on saving throws against enchantment and fear effects.

At 12th level, when entering a bloodrage you can choose to have bat-like wings grow from your back, giving you a fly speed of 60 feet with average maneuverability. At 16th level, your fly speed increases to 80 feet with good maneuverability.

At 16th level, when you charge the attack you make at the end of the charge gains the benefit of your hellfire strike without expending a use of it. If you already have hellfire strike active, the fire damage ignores fire resistance of 10 or lower.
