I have to say that the Protector gave me a pleasant surprise at the start of Chapter 9. I raised it all the way to level 12 while I finished that darned Tournament. Then I fought it with two dragons that I'd never have picked it to go against: A level 12 Illusion (black-purple), and a Level 10 Ninja (Champion) It took the Illusion with a mB, and the Ninja with a M.
I hope his luck, and yours holds out and you breeze through them.
