Sounds nifty.
Oh, and Legendary Weapons? Sure, but probably further down the line. Or at least for unlocking their full potential at the least. Give them in a degraded form if they're gonna show up earlier. Maybe make a point out of it to restore them.
Would a skinwalker or shapeshifter be viable? If yes, would they need a focus like a pelt of the animal they're transforming into, an actual animal to transfer their mind to, or some other limitation?
If there were some votes for Aquile, I'd definitely throw my vote at it, but alas. I guess I'll just have to rely on my mangoes for that fix instead.
So the Score it is!
