its really not good build /:
i see no point mix the P and E skills in the way u did..
for what max the Roar ?
for what flash slash ? -its useless for every sword master build.
and for what multuple sword slash if u not use critical passive ?
hmm there is many many more but u need to get the idea of sword master.. his power is build on critical P.
read more about sword master befor u try make ur own build.
i dont have any bad though about spirits sowrd but this build is not well /:
