Well done!
Not sure why you had difficulties with Korvaak, for me it was stomping content after around level 30-35 Veteran.
Your build is fine, but there’s room for optimization. E.g. your helm and boots. They are low level, so behind in armor rating vs enemy damage arms race. There doesn’t seem any good excuse to use them, you can pretty much swap them to some greens. Helm is especially easy since there’s a MI one.
Other than that I don’t get why you’re using Corpse Dust for example, you should have access to Mark of Illusion already. You’re also using Antivenom Salve in helm even though you should have access to Sanctified Bone and Runestone. And your shoulders are empty too, if you don’t know what to put there a second Scaled Hide is a good choice. You can check with this guide of mine for component selection:
It’s a shame you don’t plan to carry on with this build, you’ve almost reached Abomination’s proc and this is where it becomes a lot of fun dealing with crowds.
