I made this build over several hours and there are so many things I changed and tried to make it better. I hope some of you have ideas how I could improve this build or if I missed something obvious. The gear is already pretty juicy, but I know how to craft them. At the moment I'm not satisfied with physical defense. I tried to reach some good amount of block and armour, but i cannot do it while mantaining enough omniscience. Thank you for looking into this build!

Build PoB (Community Fork): This is my Build I want to work towards in Expedition. What do you think of it? Are there any major flaws? I appreciate feedback!
