Question about drop chances

Question about drop chances

Example:
-

M'avina's Embrace
-

Leviathan

In my playing experience, I get M'avina's a lot lot lot more often than

Leviathan.

Both are Kraken Shells, so the required monster level for dropping the base is the same for both.
But M'avina's qLvl is 21, and

Leviathan's qLvl is 73.

Question is: Given a "

Kraken Shell - drop-capable" monster killed, what is the factor the determines the drop odds for M'avina's and

Leviathan?
Is is just a Set / Unique percentage distribution? Or is also a qLvl factor? If so, how is qLvl determined ? Is is static forever, or based on a kill event?

I admit I only have a partial knowledge of overall drop logic based on TClasses and monster / area levels

Thanks

Errata (2024-08-30 10:35): It is Treasure Class (and not qLvl) that limits monster/chest level that can drop a item
(in the case both

M'avina's Embrace,

Leviathan and

Kraken Shell have Treasure Class 81)

----

From what I remember ... for a item have a chance to drop (beside other factors) the monster/chest level most be >= qLvl of the item, so only monster/chest L73 or more may drop

Leviathan.

And once the game chooses the item that will drop (in the case

Kraken Shell), when it determine the quality of the item, Unique has less change than Set.
chances: Normal > Magic > Rare > Set > Unique

So if monster/chest is L72- you have no chance to get

Leviathan
if monster/chest is L73, you have more chance to get

M'avina's Embrace than

Leviathan

On the same vibe... since I started to keep a tracking

I dropped
14

Immortal King's Stone Crusher

Ogre Maul
8

Windhammer

Ogre Maul

almost twice more the Set version...

(2

M'avina's Embrace and 0

Leviathan...)

What confuses me is that the base TC for dropping any

Kraken Shell is TC 81, so M'avina's and

Leviathan's qLevels are lower than their base item's level, so it leads me to think that any

Kraken Shell dropping monster can drop either M'avina's or

Leviathan. And other factor is responsible for Set / Unique choice odds.

Am I talking nonsense?

PS: I am talking about odds for a normal / champion monster who has levels and TC classes fixed by area. Not talking about bosses who has fixed Monster and TC levels.

BTW, if a chance for choosing Set is minimal but twice as the chance of unique, the drop odds for your

Ogre Maul case make sense!

I think made a big confusion...
It is Treasure class (not Quality Level) that limits monster/chest level that can drop a item (that's why very few non-TZ monsters may drop

Griffon's Eye - Treasure class: 87 Quality level: 84)

(but the part that "Set quality" have more chance to happen than "Unique Quality" is right )

Really don't know what is the purpose of Quality level on Unique/Set item...

On Magic/Rare/Craft, Quality level (together with ilvl and "Magic Level") determine the max alvl of the affixes (OK)

I remember the case of very specific items like

Arachnid Mesh where the item's qLvl (87) is greater than its TC (63), so only monsters with level 87 or higher can drop Arachnid. In this case qLvl plays a role.

Seems like max between qLvl and TC is used to cap the monster/chest level

I had a question. An additional restriction on unique item drop chances is that each unique can drop only once per game session/reset. If the same unique tries to drop again, it will create a “failed unique” (a rare item with triple durability). How does this work when there are multiple uniques for the same base?

Say a group or monsters are high enough lvl and TC to drop both

Tyrael’s Might and Templar’s Might. Say that each monster has a 1 in 1000 chance to drop a unique

Sacred Armor. So each monster has a 4 in 5000 chance to drop a Templar’s Might and a 1 in 5000 chance to drop a

Tyrael’s Might, since (I’ve heard that) 4 in 5 unique Sacred armors will be Templar’s Might when the monster that dropped it was high enough lvl to also be capable of dropping a

Tyrael’s Might.

Say now that you kill one of these monsters and it drops a Templar’s Might. Do the remaining monsters now have a 1 in 1000 chance to drop a

Tyrael’s Might, a 5X increase, or does each monster now have a 4 in 5000 chance to drop a failed unique

Sacred Armor and an (unchanged) 1 in 5000 chance to drop a

Tyrael’s Might? I imagine it’s the latter, but I’m not sure…

Besides the above example, this question could have significant practical applications any time you get a unqiue ring or amulet to drop and it’s one of the trashy and common ones.

Not sure if that restriction still exits on D2R
But Set items I already dropped the same item twice on the same boss one time (if I remembered correctly was

Isenhart's Case...)

IIRC, the way it works is that the game takes rolls in descending order of quality (from unique to magic for what we care about (normal, socketed, superior, etc. come afterwards)) to determine what the item will be, affected by your Magic Find with inversely proportional effectiveness. That is, it first rolls to see if the item is Unique with heavily decreased Magic Find, then Set with greater effect, and so on. So I think that's why you end up having a greater chance to get a set item than a unique, for example.

I made a little spreadsheet to keep track of this for myself (and to know where I am in the horrible uniques diminishing returns curve).

The restriction that a unique can only drop once per game DOES still exist in D2R, I’ve seen it happen and result in failed uniques.

In 2000, before LoD, there was a restriction that a unique item couldn’t drop if it already existed in game. That was taken away a long time ago due to how lame it was, but it allowed players to produce an SoJ with just like 1 million gold by gambling while having a

Manald Heal and

Nagelring but no SoJ. Odds of getting a unique when gambling were also insanely higher, like 1 in 30. But I digress…

This digression does raise an interesting question though: does finding a unique ring that is NOT an SoJ increase your chances of gambling an SoJ within the same game? I think odds of gambling a unique are supposed to be fixed at 1 in 2000. Say I’m sitting on 10 million gold that I want to gamble on rings and then I find a

Nagelring. Should I run to

Gheed within the samw game I found the

Nagelring and gamble rings because the chances of gambling an SoJ has now increased by like 25%?

Curiously enough, for the same period of time playing D2R online non-ladder single player games only (multiple characters) I managed to find 2x

M'avina's Embrace and 3x

Leviathan. Go figure...
