[review] Red dragon racial progression class

[Skaeren]

So I knocked up a progression across 20 levels for playing as a red dragon.
I would love to get some feedback on this.

I am retiring my current character in our Kingmaker campaign, once we get to the next module, and wanted to play a Red Dragon. I put this together in an effort to make something relatively balanced (please, I know it might seem op on paper, but there are many factors that don't translate to paper, like how red dragons are likely to be hunted, and making equipment for them would be very expensive)

The only other thing I could think of would be to ditch racial hit dice entirely, and assign them a level adjustment. What do you guys think an appropriate level adjustment for them, by age category, would be?

I'm looking for someone to comment on this. I'm the GM for the group and to put in context, the party are currently non-optimized core classes and a CR adjusted Half-fiend without Spell Resistance (yet).

How does this advancement compare to a straight 20 in other classes?

The class column seems to suggest this character has access to other classes built into their own progression? If so, this class is waaaaaay overpowered.

Assuming I am mistaken, the Draconic Power feature is way overpowered. A real mature adult red casts as a 9th level sorcerer.

This class gets almost everything by level 18. My guess is the player will multiclass one level of cleric and one level of sorcerer. Now you have a mature adult dragon not casting as a 9th level sorcerer, but instead casting as an 18th level sorcerer/18th level cleric. In addition if the CLASS column means they get another class' abilities as well, they take all fighter and are now a dragon 20/ Sorcerer 18/Cleric 18/Fighter 13

If I were another player in this group, I would feel out gunned.

That ability alone is issue. The ability to have another class built within is strange. Why do the dragons racial abilities improve on the levels that the dragon is gaining class levels?

This class pretty much gives a gestalt class of dragon/whatever/cleric/sorcerer.

Unless you go back and let the others make racial classes to go alongside regular classes as well, this is way too much, in my humble opinion.
