I agree with Majushi. Clinging Breath and Dragon's Wrath don't augment your breath, their seperate powers, so Empower Breath etc. don't apply.
Dragon Wings [Dragonborn]
Prerequisite: dragonborn, Str 15, trained in Athletics
Benefit: You grow draconic wings. Any jumps you make are treated as if you had a running start, and you calculate the distance you jump with high jumps in squares, just like long jumps. The distance you jump can exceed your speed.
You can use an Athletics check to reduce falling damage instead of Acrobatics.
Oh, there certainly were follow-up feats. Here are a couple:That's very cool, both mechanics-wise and flavour-wise. I might ask (beg) my DM to let me take it. That said, there should be a follow-up feat that allows you to get even bigger wings (maybe str 19 minimum) and allows you flight (maybe a rest once every few rounds, depending on your con bonus, say).
I was thinking of making an epic-level Dragonborn class, called Dragon Re-born. Basically it's a ritual that turns you into an actual dragon, with all the pluses and minuses that entails. You start off small and get larger, with the ability to shape-shift back into your pre-cocoon dragonborn shape for when you need it. Dragons should have that magical ability, anyway. (I admit, I haven't read the 4e dragons yet, being that I like to have surprises and I'm just a player)
Dragon Pounce [Dragonborn]
Prerequisite: dragonborn, Dragon Wings
Benefit: If you make a jump or fly as part of a charging bull rush, and you succeed on your bull rush attempt, you may knock the target prone instead of pushing it 1 square.
Dragon Flight [Dragonborn]
Prerequsitie: dragonborn, Str 17, Con 17, Dragon Wings
Benefit: You can swap a 16th-level utility power you know for the Dragon Flight power.
Dragon Flight Feat Power
Daily
Move Action Personal
Effect: You gain a fly (clumsy) speed equal to your speed + 2 until the end of the encounter.
Squires among the Winged Knights were capable of great leaps, making them very mobile in the battlefield, and the senior officers were capable of tackling flying foes and bringing them crashing to the ground. These capabilities marked the Winged Knights as a form of mobile infantry, as opposed to the full aerial force of true dragons, and some trace the origin of the word “dragoon” to the order. Winged Knights riding wyverns and leaping off to fight as separate combatants weren’t unheard of. And the ability of the highest Knights to cover great distances on the wing made the Winged Knights the most effective emergency response force in the empire of Arkhosia.
