?? on Warshaper Prestige Class

[R-Hero]

I recently updated my e-tools and I came across the Warshaper Prestige Class.

I can't seem to find any printed material on the subject matter.

Could someone tell me a little about it or at least point me toward the right book.?

I added a couple of levels to a fighter I just leveled up and it seems to be a route I want to take, if it isn't too off the wall and I meet the requirements.

Thanks in advance.

Warshaper is in Complete Warrior, IIRC
