++++++++++++

Beside the slight 1.5def avg off, base def math added correctly.
Testing change when Defender is up. It seems the rolls only applies to base DEF (gear only) without buffs.
I did not try with Protect and Atma buffs. But so far, it isnt looking good. If I have some time, I will update new numbers.

From some quick testing me and a brd freind did after testing we found an 11 roll was 50/255% increase in defense. Granted we only tried it with a few gear sets but that precentage fit each test.
