Here is a prestige class for those characters wishing to pursue the path of the dragon metamorphosis.
Basically what I have done is allow the abilities of the defiler metamorphosis spells from Legends of Athas to be applied as free factors (in terms of spellcraft DC) when gaining a level of this prestige class. At the same time the character may also add additional factors of his own, if desired.
This offers the dragons (and the avangions when I write it up) a moderate power boost compared to what is offered in LoA. The entry requirements are far stricter, though. Check out the PDF below.
It is meant to be used in conjunction with my additional factors for the metamorphosis seed here -
