__TOC__
Loot is rolled when you open the container or kill the mob.

Whoever opens the loot first or kills the mob first is the person whose luck is used to calculate the drops. 
(It is not confirmed if Bard's Unchained Harmony rolls the loot table when it opens the containers.)

Luck is capped at 500. 
It is possible to reach the Luck cap:
*50 from [[Bard#Perks-0|Bard's Wanderer's Luck]]
*150 luck roll from a large [[Potion of Luck]]
*10 from craftable [[Hands#Craftable_Hands_Armors-0|golden hands]] armor piece
*40 from [[Golden Cloak]]
*250 from [[Enchantments#Table_of_Enchantment_Values|max enchantment rolls]] ''on other gear''

==Loot Drop Tables and Drop Rate Tables==

Each drop instance makes use of three pieces of information: the Loot Drop table, the Drop Rate table, and the player's Luck.

Loot Drop tables list all possible items for a specific drop instance, and for each item therein it associates a Luck Grade. 
Drop Rate tables assign a "rate" to each Luck Grade; when normalized, these rates represent the probability of getting a drop of that Luck Grade.

Each Luck Grade's drop rate is split evenly between items that share that Luck Grade. This means that items sharing a Loot Drop table and Luck Grade, will always have the same probability of dropping. 
However, be aware that Monsters and Containers can have multiple Loot Drop Tables, each with their own Drop Rate table. See [[Lich#Loot_Tables|Lich]] for example.

A Drop can be rolled more than once, but each roll is independent of the others. 
Lich rolls their gear Loot and Drop tables twice, theoretically making it possible (though extremely unlikely) to get two Artifacts from a single HR Lich kill.

==Luck Scalar==
[[Luck#Luck_Scalar|Luck Scalars]] are one piece of information needed to calculate drop probability at X Luck. 
The calculation is not a simple multiplication, so do not expect Uniques to be 4.382 times more common at 500 Luck. 
The true effect of Luck varies depending on Drop Rate tables and Loot Drop tables.
See the [[Luck#Probabilities_from_Luck|Luck]] page for an in-depth explanation of how [[Luck#Luck_Scalar|Luck Scalars]] affect probabilities of drops.

If the Luck Scalar Table and Graph don't cover a Scalar value you wish to see, use the [https://www.desmos.com/calculator/rvig6eeqeb desmos graph].
The desmos graph displays the LaTeX equations which are continuous curves, but keep in mind that fractional values of Luck do not exist.

==Probabilities from Luck==
To calculate the drop rate at X Luck there are three steps. 
# For each Luck Grade's Drop Rate apply the corresponding Luck Scalar. 
# Find the dot product between the Luck Scalar vector at X Luck and the Base Rate. (This is the same as adding up each term from the first step.) 
# For each term in the first step divide by the dot product from the second step to get the new drop rate at X Luck.
<tabber>
|-|Quest Drop Example=
The table below is the Drop Rate table of Quest Drops.

Every monster with a quest drop uses the Drop Rate table. 
However, depending on the monster's Loot Drop Table, many of the Luck Grade rates will be associated with dropping nothing.

And in other instances, like [[Demon_Centaur#250-1|Demon Centaur]], a Luck Grade's rate may be split between two Loot Drops. 
This will not affect the calculations below, but they will determine an individual item's probability.

|-|Gold Coin Chest Example=

The table below is the Drop Rate table of the Gold Coin Chest.

The Loot Drop table is rather simple. At Luck Grade 0, "Junk", you get nothing. At Luck Grade 2, "Common", you get 1x Gold Coin Chest.

Notice that despite the [[Gold Coin Chest]]'s item rarity being unique, its Luck Grade is actually Common. 
Item Rarity does not equal Luck Grade, despite the two being equal for most items.

It's worth noting that you can calculate probability at X Luck from either the Drop Rate table ''or'' the Drop Probability at 0 Luck table. 
Using the Drop Probability at 0 Luck table works because the Luck Scalars are all 1 and you have to normalize regardless of using the Drop Rate or the Probability at 0 Luck.

The wiki does not display the Drop Rate tables themselves, however it does show the alternative.
