I'm creeping my way deeper into Delve. I hit lvl 79 tonight, upgraded my chest piece, bought another jewel I needed and fixed my gems a little bit. Even though I'm ages away from completing the build, everything is working quite nicely. I think I can still get the build doing more than 10 times the current damage so I still have a long ways to scale the build. Each jewel I get really boosts the damage and right now I'm sitting at 4 of 13 jewels equipped in the build. After that it's just a matter of adjusting my skills slightly.
I don't think any crazy new craftable mods exist for this build, I was kind of hoping some would pop up but I haven't seen anything yet. A random +1 to golems on gloves or boots would have been super nice but I don't think it exists.
