...So, this is what I wanted to do. A good break through.

I got terrible Quest1, but got better in later quests. I think we can go sub 11 if we get an ideal run. (Though, it may require plenty amount of attempts, because there are many stage MODs to ruin the run)

BTW, I'm really happy that I came up with this build, because Demolitionist is one of my favorite mastery, yet difficult to use. I could finally utilize its potential.
