Solo plowing lightblue undead the fastest way to evolve them?

Seems like you need more kills if you duo/group to evolve 1%.

Level of mob doesn't seem to make a difference as long as it gives xps.

Do you have to set level xps to 100 to evolve faster?

I couldn't find much info on how exactly evolving items work now. Other than they used to steal xps but now they don't. They only steal xps from eachother.

Breakneck earring if it matters.

I found clearing CoD to be a reasonable way to evolve the ring I use. I initially was just killing whatever (db undead), but after I went on a tribute-farming excursion, I noticed I got a pretty good evolution rate doing the Carprin cycle. I cleared all the undead and then the rest of the zone, after undead were down.

I did some LDoNs to evolve my belt. I could get about 5% a LDoN on it, plenty of undead in butcherblock and south ro LDoNs. And yes soloing is faster than grouping for evolving items go go soe with that screw up.

Evolving items, to my knowledge, work as follows:

Every mob that you kill, either solo or grouped (NOT raid kills) will give you a set amount of experience per kill. There is no way to make it go at different rates, it's either all or nothing. From what I can recall, light blues were the best (and if undead still give the 10% exp modifier, that would be better) solo kill per 1%, group mobs would be the best exp mobs you can get.

Then there's also a way to transfer evolving item exp from one item to another using some container in Coranthus. I'm not sure exactly how it works, but I know you lose some of the exp in the transfer (not sure how much)
