The Solar charms are unbalanced, and you can make an argument that the lunar charms are too.  (it mostly depends on whether you like kaiju monsters and have read the erratta for claws of the silver moon)  But the dragon charms are good as long as you apply the erratta so that every dragon blood doesn't have about a dozen dynasty charm effects still lurking around from the first age...  Although it can be fun to give every dragon blood the ability to know what dragon blooded mitochondrial eve would have wanted in that situation, and 99% of the time it's "run away and have more babies to kill that thing."<br/><br/>I figure children who are different aspect from their parents comes as a result of recessive genes from previous generations.  Although you could certainly make the same argument for dragon bloods exalting out of mortals.  The fact that one in 5,000 to 10,000 mortals exalts as a dragon blooded, while 30% to 90% of a dragon blood's children exalt as dragon bloods seems to suggest it might all just be genetic.  (The 30-90% figure comes from the Erratta though, and it's been criticized for being too high.  The number is probably lower for males impregnating females and about that high for females, though without charms a dragon blooded female can only safely bear children once every 50 years.)
