Current stats on my blade:
Took forever and about 30M gold to get phys out of the 0% -> 22% -> 0% cycle. I want to get critical up higher, but can't afford it if it does the same thing as phys did, so I'll leave it as is for now.
I traded for the blade when it was at +5, and made it +7 myself the other day, 5->7 no problems (couldn't believe it -.-)
Now, I just need to get a PT and level past 70 and farm up all my sp when I get to 77

Might put that off for Euro though, not sure yet.
