Not the most noob-friendly builds, I finally gave this a shot after trying and giving up on previous incarnations but its definitely a strong glass cannon.
You are pretty darn squishy starting out, thankfully most things die fairly quickly if you know how to set it up and keep the cold infusion train rolling. It was probably easier to get Powered by Verisium in 0.5.0 so that part is a pain point for me.
I would try to squeeze in Temporal Chains once you're in maps to deal with being swarmed, as your curses are pretty boosted. Early mirrors will absolutely destroy you unless your damage is already through the roof.
Again, definitely not for the faint of heart, as you have to know what you can facetank through life remnants early on, and what you can't. It is nice to see stuff melt so quickly, finding good jewels is pricey in 0.5.5 which is the sole bottleneck for this build.
