This is my tankiest character yet although tormented feared still get me. The regen. on this char is insane with Scion's Guardian node! Then with the deadeye's node with increased mark effect combined with Nimis and Sniper's mark, we get roughly 42 projectiles? Either way, if you stand right on top of the enemy you do tons of damage, as seen when I fought Searing Exarch in the video. All my rare gear I crafted myself, easy enough with dense/eldritch chaos spam.

This build would probably be good with deadeye and inquisitor too!
