noooooooo…
Maybe the tooltip just doesn’t show values below 10 or sth.? 
How do I even sum this all up? It’s a bloody clusterfuck 
Let’s just try to figure it out one more time… if 35% more fire>vit conversion can actually complete the conversion here, somehow – but only when PoT3 is involved, too – then those two must compete for some form of 100%, right?
Okay…throwing in the darkflame chest.
So…if hammy is correct,
Or…darkflame is bugged…
I don’t think so; just tried to replace its conversion with fire>lightning from Cindertouch, and the fire dmg still disappears completely with those, too…
Hmm, I’d just summarize what you are telling us here.
Not 100% conversion = results
Add darkflame (which is theoretically 100% = 45+45+35, etc) = results
and doesn’t make sense. etc.
It’s probably one of the 2:
a. One of those hidden/unexplained details regarding mechanics (aka. “working as intended”)
b. Oversight in the coding underpinning the order of conversion (btw, I have 0 coding knowledge, so I’m really speaking out of my bum here)
Hah! You know what was missing in our theoretical calculations when compared to my empirical findings?
My actual gear rolls.
with only 52% fire>vit and 46% fire>acid I could never reach full fire>X conversion without another item – until just now, when I equipped a second Sigil of the Depraved for 17/12 PoT3 with 50% conversion.
Lo and behold: no more fire dmg. Again.
But if fire>acid from PoT & fire>vit from off-hand compete on the same level – where do I lose my dmg, now? 
Still doesn’t make sense…
Evidence (see ring slot):
I’m not quite sure I understand this. Could you please rephrase it for my benefit?
EDIT: LOL. Loving those 5x gdstashed cindertouch
As far as I understand, both the fire>acid and the fire>vit conversion apply at the same time right after ele>vit conversion, I suppose. That is the only reason why, together, they could remove my fire dmg completely, right?
(the whole char is GDStashed already, anyways 
)
I see. So…when you equip a darkflame chest piece, does the conversion work like a weighted pool?
i.e. 52% on offhand + 46% from pot3 + 30ish% from chest = 128 marbles
Which means that pot3 will result in… 46/128 = ~36% fire/acid conversion
If this is the case, then everything is hunky-dory.
If it isn’t, then it’s more proof that hammy’s right.
EDIT: Still wouldn’t explain the DPS loss if they were indeed working at the same operator-level.
Yup. Acid dmg decreases once Darkflame is equipped.
The only other thing I can think of is that could explain is elemental is coming after single.
Which means elemental basically sees no conversion from fire after 50/50+ single. You gain some %vit from Pot but lose 25% of the flat conversion due to fire conversion loss. 50/50 meaning Pot is 50 and the rest is 50, or whatever is the over 100% weight.
TLDR. I don’t know.
Edit: You can try removing the belt to blow up this theory, though. See if numbers are similar.
Regardless, if your conversion total prior to using darkflame is below 100%, you shouldn’t suffer a dip in vit damage.
My money is on hammy’s theory
^I don’t quite follow, mate.
Me neither 
Do you mean that the dmg loss comes from a reduced ele>vit conversion, @hammyhamster1?
Edit:
Yeah, it’s definitely the one where the dmg loss numbers made the most sense up until now…
I guess the TL;DR version of this entire fucking brain contorting, mind fucking mess is this -
Yes, I meant you might have reduced ele->vit due to order of the elemental conversion. Maybe it is not first. But just guessing.
BTW, I was looking at this again, and comparing it to your earlier screenshot…
Why the heck is your vit damage increasing even with crappier conversions? Maybe it’s just from the increase in %vit damage?
I give up.
I mean, you can totally help with that if you want!
But maybe hammy is right and all of this isn’t necessary in the first place?
But which part of my fire dmg could still be converted by the belt if your theory was correct, @hammyhamster1? Wouldn’t it all be vit/acid by the time ele got its turn?
Well, if single was not 100%, then there would be some fire left and elemental would only do 50% of that.
In this theory, that is.
If you have 90-ish% single, removing the belt should only see 5% difference if it is this way. Belt has no other vit bonuses.
With such a marginal increase of dmg, yeah, probably just the different ring values/increased vit% from PoT3…
