This build has the right idea, but The Ram makes it infinitely better because ANY voidwalker charged melee triggers life steal on hit, allowing you to use life steal and soul rip simultaneously. Oh, and by the way, The Ram also gives you increased armor! So if you max out your toughness stat on top of all of this, you'll basically be an unkillable source of endless purple space magic. So if you like this build and you're lucky enough to have The Ram, USE IT!!! It's my current build and I highly recommend it.
