Moving +1 spec though recomb

If my current base is str/int and I want it on a necrotic (dex/int) im assuming i have to move it 2x?

from str/int to int with evasion essence
then
form int to dex/int with armour essence?


is this correct?

There are a lot of people that report this method doesnt work anymore. I am not sure if they followed the steps 100% correct, and both their bases could not roll naturally the mod they introduced by essences so they messed up somehow. I have not tried to test it myself, so I am curious about it too. The thing I have tested though is that recombinator when it is about to choose base, at least in the predictable mode, it is not 50-50. It favours the base that has the "big"/"rare" mod.
I have seen a lot of videos claiming you can never lose, with the unpredictable recombinator mode, the "rare" mod of your item, in this case the delve mode +1 to summon spectres. But also a lot of comments and threads under them reporting very wild results, like no modes transfered , they got a rare item with 0 modes (including myself), or having 0 prefixes/affixes. Or transfering the non native mode like +armour to a base that cannot roll it, like int body armour. If you are playing some weird league I would wait to confirm it first or at least experiment with it in some other league with more recources.

I just did a quick experiment. Well it is only 1 try so it only proves that "sometimes it works" but defently disproves "never works". Also my suspicions that recombinator doesnt not have 50/50 chance t o pick a certain base when one of them has a "bigger" mod, but favours the base with the bigger mode is somehow confirmed. Here is a very short video, sorry for the sound microphone very bad 5 euros 15 years ago, sorry for the english non-native speaker.

So lets say it works 100%, keep in mind that you might have to get a lot of bases trying to transfer it to the necrotic armour, because I think it recombinator favours the base the "exotic" mod is on.
But lets say you finaly get necrotic armour with +1 spectre, then what?Try fracture it?

Finally here is what you need as you said already in your post:

At the second recombination try, I got it to move into the necrotic armour:
