help with a dual wielder

Hey guys, been playing this game for YEARS and so stoked it is finished. With that being said, I’ve never really gotten much into crafting a truly hardcore viable character. On my best character, a lvl 58 conjurer (Shout out to the lazy pokemon master!) I picked up a weapon, the crimson spike. This thing looks just beastly and I figured why not make a build that can use it. I was thinking some sort of life steal dual wielder but I have no idea where to start.

Thoughts? Ideas? Mocking laughter at my newbish ineptitude for failing to come up with something myself? Discuss!
