Okay, so I created a poison generator build on D3 planner, copied the link... And it was Coldkil's build. No idea what went wrong, but something sure did!
Either way, it refused to simulate the damage and a few of the key legendaries haven't been updated yet, but I think it'll work.
Will it be totally 100% clearing Grift 100 solo viable? Probably not.
Do I care? Not even a little .
It'll be enough to play until I get bored and move on to something else. I'll probably make a more cookie cutter build with my next seasonal Necro, but for now I want to make the slightly odd build that first came to mind when I saw the Inarius set.
