Half-Dragon (3.5e Racial Paragon Class)

Half-Dragon
"Also, dragons are pretty. Very pretty."

Half Dragon is a character class that can be used to make a monster into a more "dragon-like" monster. It can also be taken by player characters who want to be more dragon-like, for whatever reason. Maybe they got spilled with dragon blood and became dragon-like themselves. Maybe their mother slept with a dragon in disguise. Maybe the dragon wasn't in disguise. I don't want to hear about it.

Class Features
All of the following are class features of the Half-Dragon.

Weapon and Armor Proficiency: The Half Dragon gains no proficiency with armor or weapons.

 (Su): A Half Dragon is able to emit a deadly breath weapon. The energy type of the weapon is appropriate to whatever dragon type is involved in the dragon-half. As appropriate, it will either come out as a cone with short range, or a line which is twice that long. The breath weapon does 1d6 of damage per character level (or CR) of the Half Dragon and the Reflex save DC is 10 + 1⁄2 Hit Dice + Con Modifier. Using this breath weapon is a standard action, and once used it cannot be used again for 2d4 rounds.

 (Ex): Half Dragons gain 60' of Darkvision and see 3 times as far in limited light conditions as per Low-Light Vision.

 (Ex): Half Dragons gain an Enhancement Bonus equal to 1/3 of their Hit Dice (rounded up) to their Natural Armor bonus to AC.

 (Ex): 2nd level Half Dragons are immune to sleep and paralysis effects, as well as the energy type that they themselves breathe on people.

 (Ex): Upon achieving 2nd level, a Half Dragon is blessed with increased Strength. She gains an Enhancement Bonus equal to 1/3 of her hit dice (rounded up) to her Strength score.

For example: a Half Black Dragon would gain subtypes of [Dragon, Water].

 (Ex): At second level, a half dragon grows dragon wings. They may be small and cute or huge and cloak-like. But regardless of size or mass ratios, they allow the character to fly half again as fast as their land movement rate with average maneuverability.

 (Ex): 3rd level Half Dragons have Spell Resistance of 2 + Character Level (yes, only 2 + Character Level, I'm not even kidding).
