A question have I!
First of all, I really like what you've done here. I was trying to come up with something similar myself, but you beat me to it.
Now, on to the question.
I have been working on a class based in large part on the Summoner. This class is meant to represent a character who can transform himself into a "monster" of one sort or another. Kinda like a werewolf, only not a race, and can be used to represent any number of other things as well (such as a "wizard" who's only learned one spell -- to transform himself into a hideous abomination -- or a "half-devil" who can take on the form of her devil parent.
So my question, then, is if you'd be willing to allow me to take your work here and integrate it into my own. I plan on posting the class up on the homebrew forum when I'm done with it (which may take a bit, it's been more work than I thought when I started.)
Anyway, thanks for taking the time to read this. I'm looking forward to seeing more.
