How Do Marks and Curses Interact with Hand of Chayula in PoE 2?

Hey everyone,

I'm trying to understand how Marks and Curses interact when using Hand of Chayula in PoE 2. My setup includes:

Hand of Chayula (splits my attack into six hits)
Sniper’s Mark
Freezing Mark
Conductivity (Curse)
Hypothermia (Curse)
My questions:

When I hit a boss with Hand of Chayula, will all of these apply at the same time, or does only one Mark and one Curse apply per hit?
Do I need to hit the boss twice for all effects to be active in the same second?
If I have room for two Curses (via Whispers of Doom or another method), will both Conductivity and Hypothermia apply together, or is one randomly chosen?
How does the game decide which Mark applies first when using two? Would the last one cast override the first?
Would love to hear from anyone who has tested this or understands the mechanics in PoE 2! Thanks in advance. 🙌

Hi, as far as i know the HoC can apply curses but each curse consumes one out of 3 charge and each charge has a 0,15 second cooldown. So it's limited to 3 curses per 0,15 seconds. I havent managed to test this limit myself but i am playing a HoC build with impending doom and while the theme and style are really fun the interaction itself feels clunky.

I have specced for reduced duration on the skill tree so that the duration of my curses is less then my attack time, enabling impending doom on every attack by HoC.

Cursed ground does not support curses socketed in HoC for some reason

Curses applied by HoC only "stick" to the target that the attack hits. But the doom blast from impending doom seems to do AoE damage.

The AoE radius from doom blast feels quite small

I am only level 50 yet but i think that combined with a high mana pool, archmage, and decent radius the build will become more dynamic.
