So here we go guys! I've been working on this build for over two weeks, maximizing everything and trying to beat as high GR as possible. I must be TOO MUCH NERD with this, but it's just what i am :DD
Check the written guide for details, it's VERY IN-DEPTH
PS: I believe this is highest Tempest Rush clear in the world as well I tried to do 83, but it's pretty damn fishy for my low paragon and lvl75 augments. I believe high paragon players can push this into 90s.
