Witch/Blood Mage Leveling Build?

Hey there, new to PoE.

Was hoping to ask around here if anyone went mainly for Curse/Chaos damage for their Witch while leveling? Not a big fan of pet/summoner classes but i love edgy casters/warlock types. I see that a lot of people are making Hexblast work however what build are people using to get there?

I'm currently level 37 and I've been struggling to clear packs in Act 3. Essence Drain + Contagion is doing alright but takes forever to kill. Unearth was good early and the bodies are nice but even the minions it spawns take a while to kill stuff now that i often prefer using Detonate Dead. It also takes FOREVER to kill any rares now, more so the unique bosses on the map.

My current set up is this:
Chaos Bolt - Inevitable Crit, Execute
Malice
Life Remnants
Essence Drain - Chaotic Freeze, Scattershot, Chain
Contagion - Hinder, Persistence
Detonate Dead - Corpse Conservation, Elem Focus
Bonestorm - Brutality, Arcane Tempo
Skel Warrior - Meat Shield, Elem Army
Withering Presence
Grim Feast - Herbalism
Blasphemy - Despair, Magnified Effect

Already have quite a bit of my passives invested into Chaos dmg and Curses with nodes like Void, Master of Hexes, Controlling Magic and omw to get Pure Chaos.

I tried making Bonestorm work, but it felt a lot clunkier than i thought it would even with Arcane Tempo. I could invest in a bit more phys dmg weapon with cast speed but idk how much that would help. Because if anything, i wouldn't mind pivoting my build into more bones then later on reset back into curses/chaos when i finally unlock Hexblast. I'd rather do that than be a summoner lol(no hate, just a personal preference).

Any help would be appreciated, thanks!

I had quite a difficult time getting my bone witch off the ground. I ended up leveling with elemental stuff because i hated the chaos spells. My first reaction to bonestorm was meh to be honest. It didnt really start coming together untill i fully committed to the physical aspect. I really leaned into the base crit chance, and boosted my crit stats. without the crit investment, and a lot of phys support, it does indeed struggle. I would like to see more done to support the physical stuff with bloodmage.

The 'I Win' button for pack clearing is Detonate Dead. Kill one mob, then explode the rest of the pack.

On my Bonewitch I used Cage for CC, Bonestorm for Bosses, and DD for packs.
