Drop rate

Drop rate describes the chance a certain source will produce items, most commonly killed monsters.

Mechanics

The most basic way of acquiring loot is to kill monsters. Monsters' base drop rate is currently unknown, but from testing in Kalandra and Sanctum league, normal rarity monsters are estimated to have an 8% chance of dropping any item.

Base drop rate can be modified by four multiplicative factors: the player, the area, the party, and the monster. Each category has its own item quantity modifiers. For example:

• Player/skill: legacy equipment (e.g. GoldwyrmGoldwyrm
  Nubuck BootsEvasion: (113-126)Requires Level 34, 62 Dex60% increased Mana Regeneration Rate
  (20-40)% increased Rarity of Items found

Within each category, increases and reductions are additive, more and less modifiers are multiplicative. Between categories, quantity stats are effectively multiplicative; the final value of each category is its own drop rate multiplier.

• The player/skill category has diminishing returns; its actual drop rate multiplier is smaller than the sum of its quantity modifiers. For example, a character equipped with items totalling 50% increased Quantity of Items found might receive only a 1.35x multiplier (not 1.5x), and another character with 200% increased Quantity of Items found might receive only a 1.77x multiplier (not 3.0x).

As monsters can drop multiple items, drop rate has no known maximum. If a monster's chance to drop an item is scaled beyond 100%, it gains a chance of dropping a second item. Note this is not necessarily observable from an average pile of loot: the game culls a percentage of normal and magic equipment that would realistically never be looted, and common currency items may be deferred to drop in a larger stack later. Additional hidden mechanics may exist.

It should be noted that quantity is not the sole factor in overall item acquisition. The number of monsters (modifiable through e.g. map pack size) is a multiplier for natural drops and several mechanics, item rarity may have an effect on the number of dropped items through monster reward modifiers, and many Atlas passives grant non-standard drop rate modifiers to specific item types.

Item types and their interaction with quantity modifiers

Natural drops (excluding maps) are affected by all four quantity categories. Non-natural drops may ignore some categories, ignore all of them, or interact with quantity modifiers or party size in alternative ways. The table below describes these interactions, based on ingame testing, patch notes, manifestos, and developer comments. It is not complete, and it is possible that subtler effects remain undiscovered.

Drop rate penalty

A drop rate penalty exists for currency and divination cards in areas more than two levels below your character. Each additional level beyond area level +2 reduces the drop rate of these items by 2.5%.

$$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}dropPenalty=2.5\%*(lvl_{char}-(lvl_{monster}+2))$$

(1)

For the purposes of this penalty, your character level is never considered to be higher than 68; a level 75 character receives no penalty in a level 66 area. Drop rate is unaffected in areas with a higher level than your character.

Examples

Using equation 1, if you are level 30 in a level 20 area you will see 20% less currency and Divination card item drops on average:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}dropPenalty=2.5\%*(30-(20+2))=20\%$

A level 30 character in a level 28 area will see no drop penalty:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}dropPenalty=2.5\%*(30-(28+2))=0\%$

A level 68+ character will be unable to drop currency or divination cards in areas lower than area level 27.

Version history

Version	Changes
3.25.0	The way that the Quantity and Rarity of items dropped from extra content has been changed. Generally we have added item Quantity or Rarity bonuses to a number of mechanics, such as Essences, or Delirium. On top of that we have added drops back to some leagues where it wasn't present before, like Ultimatum. In general the philosophy here is that if you are killing monsters you get loot, and if they are more difficult, you should get more and better loot. A major change we have made alongside the above is that we have changed a lot of the quantity and rarity bonuses on monsters to prevent things multiplying out of control at the very top end. Item Quantity bonuses on all Character items have been removed, though this will not affect existing items in Standard Leagues. Influenced and Corrupted Modifiers that provide Increased Item Quantity can no longer roll. Increased Rarity of Items found can no longer roll on jewels, or appear as an Implicit Modifier on Synthesised Jewels.

0.9.11	Increased item quantity prefixes have been removed from the game. Items that already have them are unaffected.
0.9.9	Diminishing returns now applies to the rate that Increased Item Rarity affects magic, rare and unique items (it affects the less common ones more). Increased Item Quantity stats now also have diminishing returns. This allows us to have higher initial values and lets us balance the extreme cases so that their rate of item gain is high but not abusive. Bonuses to item rarity and quantity from bosses or from additional players in the game now stack multiplicatively with the player's bonuses (rather than additively). Diminishing returns only apply to the player's bonuses. Added a set of Increased Item Rarity and Increased Item Quantity prefix mods.
0.9.8	Reduced values of Item Quantity and Item Rarity mods and support gems.
