Self made build that finally slayed an uber boss. Full physical Reave

This is my first post ever on reddit and I'm not 100% sure if I'm doing everything right, but here's my build from the title https://pastebin.com/qmU9qK2j . If you have any questions or tips about the build or item interactions, feel free to ask or recommend.

I usually delve to make my cash in game before anyone asks.

My next few upgrades are an Impale paradoxica to save two points in tree. A 3 stat voices for another 2 points and a woke multistrike gem.

I would not suggest anyone try to copy my build because it has a pretty rare combination of mods on a grasping mail (and honestly its a melee build,) but if you do find the items, the build is very fun to play. I'm just super proud of my creation.

Edit: Incase people want to see the full fight, I went and fought him again and recorded the whole thing: https://www.youtube.com/watch?v=zT-cVKyOio4
