I've been farming 11-10 for ungodly number of tries now (nah, maybe 30 tries), and you can imagine the utter disappointment when there's zero drop each time. Just when I reached boiling point, lo and behold, after the enemy is defeated, he dropped, not one, but TWO treasure chests, and I knew something was coming. Then I saw it dropped VAJRA, and I nearly cried tears of joy, such is the emotional woman that I am, I will never tell this to anyone ever. I have just upgraded Jennish to his 3rd and final job, and this right after Zuzu's 3rd job as well, and all this before I even started chapter 12. Am I ready or what? YAY!!!
