Vita lightning is in most cases the most effective.
You will need several setups:
* 200 fcr
* 117 fcr with oak (nature's peace)
* 117 fcr max block max dr switch with oak (0 points base dex)
Since you will be the mouse most of the time, due to maxres/abs, you will rely on either 200 fcr to keep the distance or oak to soak a hit, moving in and out to kill your opponent slowly with needle sticks.
Vs bowas, and potentially other physical damage dealers, you will need max block AND dr AND oak to stand a chance.
