My build is currently set up to run reflect maps, so there is a weird 5 points placed in my passive tree to mitigate elemental reflects. If I was focusing on pure bossing, I would drop this, and pick up a different 5 nodes near the top of the tree for even more damage. I have done every Uber, OTHER THAN Sirus. I have not even attempted Sirus, while I believe this sparker COULD do it, spark is simply not the "best" Uber Sirus runner, as the arena is HUGE, and the fight sucks horribly.

I also just realized, in the first part of the clip, I never activated Focus, which would have increased my damage SIGNIFICANTLY as it adds almost 40% more chance to deal double damage. Whoops!

I would love more eyes and discussion around the "Ideal Build" PoB. I believe this is about as good as it can get, but I would love to hear other opinions.
