New save Chaos Purifier, Solael's Devourer: help with budget build

I started over on a new save after losing my old local saves to a dead HDD. Leveling up a Purifier and I got the idea to switch over to chaos at 94 to use Solael’s Devourer from the faction vendor. I borrowed bits and pieces and made what looks like a pretty good glass cannon (that needs some farming for greens, but hello 1.1.7. And I know Grava’s a bitch!). Can anyone help with finishing touches? Any ideas how it might get some more survivability? Scads of OA but not enough DA.

I leave off Revenant because of the flat RR on the weapon.
