Some guys in one of my german forums and some japanese guys are doing a No Crystarium Run right now. They stuck at Barthandelus in chapter 11.

I know it is possible to get that far without Crystarium because I did this in my japanese version. Unfortunately my PS III is broken so I cannot try to continue with chapter 12.

LoonyBob, why can't you think of a way to prove it? People just need to make a video of their empty crystarium while in chapter 11, 12, 13, whatever.
