Folks, I have hit a brick wall, unable to do increase damage or survivability any further. Unable to complete red-rare and corrupted map bosses.

Either I get one shot as soon as I enter arena or the boss regens more health than my dps.

Would love a review/roast of the build and any ways to improve. Have loosely followed an arc build except for some high investment gears, but now seeing that my wave of conviction is doing more dps than arc or crackling lance. Dont know why, fml.

Any thoughts would be appreciated.
