Thats a great build, only minion AI is something to get used to lol
I didn't find a Exsanguinous yet, so I'm using Shroud of Obscurity for LL, which also works out pretty good.
Minion TP is for sure a great QoL, I recommend a video about experimental affix crafting if you want to craft it on an exalted item yourself.
That could maybe be a small addition to the already great build.
I'm not so sure about the Warlock points or if I should just dump all my high level skillpoints into Int 😃
