Chaos Blood Mage - Cheap and easy 1.5m DPS

After struggling a bit to make a built that works for me I ended up on this:

You can see the build in action here: https://www.youtube.com/watch?v=_rY96_860Wc

It's cheap and easy to use and I think it fares relatively well.

If you have any ideas to make it better, please do write them.

Updated build, added jewels, plus some fixes.
