Not sure on what is the best build is but this is what I am running https://share.wolcen.dev/s/TjszUqIEyj Shadow Infinity Blades and I currently have no Issues with will power to the point that I can spam out Aether Jumps with out having to worry about it's cost in between fights if it only takes 4 or 5 casts to get to the next one. My staff generates 334 Willpower on hit currently. Heres my current build: . I would say I owe my ease of resource mostly to the resource related stats in my gems and gear rather than the gates though. Also I decided to go with health instead of energy shield since I am mainly wearing gear with health and resistance. You can do either or but I personally feel like the stats I needed for the build was more often in brusier or heavy armor than anything else. Crit damage is always good possible get it in your rings. Edit: I have no uniques on just fully suited in legendaries. I have not found a unique worth equipping yet except for the magic find belt. Uniques not having gem slots is a pretty big deal breaker considering they are a lot of stats.
