I'm currently trying to work on a tempest rush build but am having trouble with damage on Torment 6 and high level Greater Rifts. Besides the Taeguk gem and the Wreath of Lighting I'm having trouble deciding what final gem I should use that would increase my damage output the most. Any help is much appreciated!
