Need advice on homebrew Curse Connoisseur Lich build

I am still learning how to build in POE2, but I have no problem clearing Juiced tier 15+ maps with this build. My biggest issue is single target DPS - I can kill bosses, but its a drag. I am also a little squishy - hopefully my last ascendancy points will fix that. I am looking to see if any of you experts can spot any obvious improvements, recommend gear changes, or maybe this approach just isn't viable?

At a high level this build is using the Soul Mantle chest unique. I can summon 3 totems, they last about 5 seconds each, when they die I get cursed. Each curse gives me a 30% increased damage bonus with Warding Fetish. Pretty sure I have max reduction on curse effects on me.

I am using both Dominion Over Flesh and Whispers of Doom so I can apply 3 curses at a time.

My curses hinder enemies with Zone of Control and then I get a 30% increased damage bonus with Hindered Capabilities.

It is a pretty active build - definitely a calorie burner 😂

Throw down Despair, throw down 3 Dark Effigy totems, Contagion, spam Essence Drain until I have to make my totems again. On bosses I rotate in Sigil of Power.

Note: Current PoB I am not Chaos res capped. If you switch that gloves to the Tempest Clutches I will be. Its a trade off of damage and protection. The only thing right now that really kills me is Volatile Plants and they kill me even when I am capped.
