Erm, well the common knowledge was confused due to 2 things:
Firstly, Zantai left the explanation at this:

There is a degree of sequence to how the conversion is applied.
Basically, the game tallies up all the conversion of X to Y together, then applies them. It then tallies up A to B, then applies it. Etc.
So in your caseā¦you have Elemental to Aether, and Fire to Aether. To the game, these are different ātypesā and so they are applied sequentially. The order of events this occurs in would take some digging, but not sure itās that important.
This occurs twice, first for conversion from skills, and then for conversion from gear (essentially the game tallies up conversion on skills and item independently, so Aether to Elemental on a Skill would be considered a different ātypeā from Aether to Elemental on an Item).
Under no circumstances can damage be converted twice though (ex. canāt do fire to aether, then aether to chaos)
Then it was apparent that the elemental order could be affected by the order of item equipping, if you were splitting to different damage types.
Ofc, if everything converts towards the same type, which is the typical case, it is a moot point and the order does not matter. The multiplication is the same no matter which order.
But this was one of the rare cases where damage is split to different types. The issue was reported over 1/2 yr ago.
Iām still not sure that Crate fixed the bug/feature but it looks like it may be the case now. Iām a bit skeptical and would like to see more confirmations; idk if it is a priority, since it is fairly rare.
So you are 100% certain that the bug is fixed and elemental is always second in the order, regardless of item equip order?
