Improved Dragon Wings
Source: Races of the Dragon
Your draconic wings now grant you flight.
Prerequisite: Dragonblood subtype, Dragon Wings, 6 HD.
Benefit: You can fly at a speed of 30 feet (average maneuverability). You can't fly while carrying a medium or heavy load or while fatigued or exhausted.
You can safely fly for a number of consecutive rounds equal to your Constitution modifier (minimum 1 round). You can exert yourself to fly for up to ice as long, but then you're fatigued at the end of the flight. You are likewise fatigued after spending a total of more than 10 minutes per day flying. Because you can glide before, after, and between rounds of actula flight, you can remain aloft for extended periods, even if you can only use flight for 1 round at a time without becoming fatigued.
When you reach 12 HD, you have enough stamina and prowess to fly for longer periods. You can fly at a speed of 30 feet (average maneuverability), and flying requires no more exertion than than walking or running.
You can make a dive attack. A dive attack works like a charge, but yoy must fly a minimum of 30 feet and descend at least 10 feet. You can make a dive attack only when wielding a piercing weapon; if the attack hits, it deals double damage.
You can use the run action while flying, provided you fly in a straight line.
