I am an unequivocal crit *****, as well as a parse *****. Anything that will up my critical hit rate, I am interested in. As such, this has caught my eye. It's been cast away for years as crap, but I underbid and got one for 20k, woo. Junk, I figured, +1, +2% increase at most! Still, I gave it a go, and just got done with a party while swapping between this, and a Hauberk. The critical hit numbers are below;
Round 1;
Jawshan: 19.75
Hauberk: 14.29
Difference; +5.46
Interesting! When I joined the party, I announced I'd be doing some parsing between the two of them, and our Red Mage mentioned he'd heard it was a +5% increase. I thought that was too good to be true, but it didn't seem so! Now, the above numbers were just prelimenary, 20~21 fights each. After the initial testing, I decided to go for the long haul. Below are the results for 60~ fights a piece;
Round 2;
Jawshan: 25.15
Hauberk: 18.75
Diffference: +6.4
That's pretty substantial. As it is now, I'm going to call that a +5% increase, looks like six, but I'm not ready to say six. Going to do some more parsing, and will probably update this post later.
