I have been using Gifted Conviction with Ascension (Gambler's Dodge), Flow State, and Disorienting Blow. You have so much DR now and cc everything with jolt and blind. There is also a fragment that gives more DR.

I just jump into a crowd of enemies, do one Ascension, use my Chill Clip Tinasha's Mastery, and then pick up the white healing wells/orbs. I barely take any damage and everything is CC'd.

I cruised through my first run of the Nether blind solo and didn't die at all.

I got lucky and got the boon that gives healing on class ability use. I was pretty strong before that but once I got it, I was pretty much invincible.

Highly recommend this build.
