Current best solo Rit farmer?

What is a good build that works with a Ritualist currently for solo farming?

I have done some searching, but most videos on YouTube are often months (or usually years) old. I have done some forum searching, but I've yet to find anything that works that amazing with current skill changes and anti-farm code from the past few months.

What you've found is pretty much going to be good as it gets. There haven't been any major skill updates that affect this build in a long time (can't recall when the original big spirit update was) and I can't see there being a lot of variance for performance differences. I'd just check the various spirit spam farm threads here and on gwpvx to see if you're getting the same level of productivity (and you'll need to do more than a few runs to make sure it's not just bad luck). 'Works amazing' is relative/subjective anyway; if it doesn't suit you go back to whatever you were doing previously.
