Multimod Prefixes+Suffixes cannot be changes

So I'm curious, what happens when I have an Item with 2 Prefixes and no Suffixes (scoured them off before).
I'm now applying Multimod + Prefixes cannot be changed and Suffixes cannot be changed.
Now I'm left with an Item that has 1 open suffix (2 Prefixes + 1 crafted Prefix and 2 crafted Suffixes) and I want to Harvest craft say "Reforge Crit" on the Item.

In my theory, the Multimod should stay on the item and the Reforge should only affect the last remaining Suffix slot, meaning it works like an crit augment.

Am I right or does the multimod get overwritten regardless?

I know it's very expensive to do so, but it might be my only way to craft a better weapon for me in SSF right now.

Thanks in advance.

this is what happened, tested to make sure
Can always check in emulator on craft of exile it hasn't been wrong for me yet

What are the 2 prefixes? Might be better ways of crafting it

well it's T1 Phys (Merciless) and T1 flat Lightning Damage (Vapourising).

I want to multimod flat phys and quality + attack speed or quality + crit.
So a basically guaranteed T1 crit or attack speed suffix would make a pretty big difference.


I thought about other ways of crafting, but I'm out of most crafting materials except ~900 alts. I don't know if i'll be able to get Merciless within 900 alts. (burned through 300 already)

Btw. I just found an fractured Staff with T1 crit multi fracture, but only ilvl 78. I might try to roll that one with phys harvests first.

Thanks for the craftofexile tip, never tried the simulator.
