http://nl.youtube.com/watch?v=fjTeVURPuZU
build 'n stuff is right there and i tried this build and it doesn't really seem to work too well
i keep dying at the end of my 3 VwK's
i don't know what i'm doing wrong
i'm giving my armor those ghostforge insigs for more armor while under effect of a weapon spell
for the rest i don't know what else is needed to make this a succes
pls help

My guess would be that you don't dodge the Spirit Rifts when VwK is down.

Because you really should. Keep moving around when you have no VwK ready, use it again and you can stop moving again. Rinse and repeat.
