Blood Nova GR 65 hitting a wall

Howdy Necros!

Playing my HC season necro called OTT

Hoping someone might point me to a bit more optimal curse nova build. I’m fast as fart and clearing mobs without issue as per the build. I feel like a hoover or dyson vacuum on turbo but the single dmg dps is dropping off, and at GR 65 i’m running out of essence before boss kill, have to jump around and eat corpses left behind currently. Still very much built for speed and not GR pushing really.

I’m thinking I can ditch my armor passive from K Cube, lose the speed for survivability and then up my intelligence, but that’s not gonna get me past GR 70.

Got a god roll on my amulet relative to what I usually see with blood passive, weapons decent too!

Hoping to be the top trangs build this HC season and cant find any over GR 73 currently
