Organ drop rarity and distribution

Hey everyone,

Out of curiosity I checked the trade site and these are the current offers:

32730 Hearts 34,94%
28833 Lungs 30,78%
20363 Brains 21,74%
7114 Livers 7,59%
4629 Eyes 4,94%

So obviously eyes and livers are more rare than the others, which is probably no news to anyone.


However, I also checked the current offers for what parts from which monsters are available and it seems that while some bosses can drop every part, most of them are not and several even only drop two.


Here are some examples:

Of course the numbers are somewhat unreliable but I think in general it could provide a basis for target farming certain parts.

Thoughts?

thoughts?

eyes are rare for some stupid reason but that's tencentggg dev's making endgame behind RNG to hold players cuz they know no better so far..

You don't need to implement endgame content for your league if you just don't allow players to participate in regular encounters. *taps forehead*

Thoughts? Any time you resort to "obviously" in a discussion, you're on shaky ground.

It might be that popular runs drop less eyes than unpopular ones do... hence we see less of them even though the drop rates would be the same if all other factors were equal. I don't know. But I know that coincidence doesn't imply cause.

For me, no matter the boss, there's always a shortage of brains. Brains just don't want to drop.

Racecourse has always been my favorite map but now it is even better. Three boss organs to choose from <3

No need to go off the trade site data when it's all been datamined, just Google POE organ calculator to see it in action

Ok, disregarding the fact that this is really overengineered (a simple excel sheet would've been sufficient); It only displays what organs can be found in what map - which is good - but not the probability depending on the boss because it doesn't take into account the actual trade data, only the organ variety in each map.

For example: There are 141 eyes from the Hybrid Widow on sale out of 1180 Hybrid Widow organs in total, so the chance to get an eye seems to be about 12%.

If you look at Tolman, the Exhumer you'll find that there are 81 eyes on sale but 220 organs in total, so the chance to get an eye from Tolman seems to be around 37% (almost three times higher than Hybrid Widow) although both bosses only drop 2 organ types.

If you then look at monsters like Oak the Mighty who can drop all 5, the probability for getting an eye there sinks to a meager 0,6% (only 4 on offer out of 694 Oak the Mighty organs) and not 20% like the tool says.

So at the very least this tool shows misleading information as the percentages can't be right.
