So, anyone who's played SO2 extensively and had Opera knows that's it really difficult to get her to make the Black and Green Systems, and FAQs generally agree that she has to be at a high level and will go through a lot of Material Kits before she makes either one.

So how the hell did she make the Black System today at level 46, with only Machinery skill level 8, and it was the first time I'd had her do it in this file? Seriously, what are the odds of that? XD I'm guessing extremely low. I literally exclaimed "Holy shit!" when I saw it pop up, and had to look at it in the inventory to make sure I'd really seen it.

Shame Laser Bit doesn't seem to be that good, though. :< Oh well, hopefully I'll get lucky again and make the Green System too. I can dream, can't I? XD
