Vermin Lord as Sorcerer

[SonsOfSauron]

As a note, you could always give them Find Familiar as a class feature, but it has to take the form of a rodent or other pest (like a centipede or something). Also, I'm unfamiliar with the original prestige, so bear that in mind.

For Aspect of the Vermin, I'd suggest going from a 10-foot cube to a 15-foot cube, centered on you (plays more smoothly with a grid).

All in all I dig the flavor but I feel several of the features are just too similar to the Dragon bloodline, specifically the first bloodline ability and the 14th-level ability.

What might be a more interesting take is to polymorph yourself into some sort of insectile abomination, instead of just sprouting wings, which could give you other benefits as well.
