I'm a bit confused here. I just did GOF VII, which took about 20 minutes this time!
Got to the dragon in about 2 minutes. That bastard kept stunning me on almost every single hit. My Eddie was literally stunned 10 times in a row at one point.

Did the chance of stun from grievous burn go up drastically? Or was that just bad luck like the book of souls?

For the record, I did win. But it just took for freaking ever. I might as well have done level X instead at that point cause of the time.
