Chests

**Chests** are interactables that are randomly scattered throughout every Environment (excluding the , , , the , and ). Chests contain items that must be purchased with gold.

## Small Chest

The basic Chest variant. A Small Chest has a chance to contain either a common, uncommon, or legendary item.

Base cost: $25

Item chances:

* Common = 79.2%
* Uncommon = 19.8%

Base cost: $50

Item chances:

* Common = 0%
* Uncommon = 80%

## Legendary Chest

A Legendary Chest is an expensive chest that costs 16 times as much as a Small Chest. However, it is guaranteed to hold a legendary item. It can only be found starting from the 4th stage onward, and natural generation is extremely rare.

Base cost: $400

There is one guaranteed spawn location in , nearby a small, yellow, glowing column, in a small cave full of foliage partially covered by a rock, ground-level, near the center of the map. It is also guaranteed to spawn in , in one out of five different spots around the map, indicated by patches of small, glowing mushrooms.

## Equipment Barrel

An Equipment Barrel costs as much as a Small Chest and always contains an equipment.

Base cost: $25

## Multishop Terminal

A Multishop Terminal features a choice of three items to buy, costing the same as either a Small Chest or a Large Chest, depending on the rarity. They come in common and uncommon variants. One item is always guaranteed visible, and the others have a 20% to be replaced by a question mark and hide their identity. After buying one item, the other items are locked and cannot be obtained from that Terminal anymore (unless the Survivor is carrying an , in which case the other items will remain purchasable).

Base cost: $25 (common), $50 (uncommon)

Multishop Terminals that spawn on  and  will sometimes sell uncommon items, while ones that spawn on , , , and  will always sell uncommon items.

## Equipment Triple Shop

An Equipment Triple Shop costs twice as much as a Small Chest. It is similar to a Multishop Terminal, but sells equipment instead.

Base cost: $50

Equipment Triple Shops can only appear on ,  and .

## Category Chest

A Category Chest costs 20% more than a Small Chest and can come in three varieties: Damage, Healing, and Utility. Each Category Chest will only contain an item fitting its category. There is some overlap between categories, such as  being both a Damage and Utility item.

Base cost: $30

* Damage Chests are red, with a symbol of three bullets side-by-side emblazoned on top.
* Healing Chests are dark green, with a symbol of a white cross on top.
* Utility Chests are purple, with a symbol of what appears to be a "U" with a smaller circle inside it.

## Large Category Chest

A Large Category Chest costs 20% more than a large Chest and can come in the same 3 varieties as its smaller variant: Damage, Healing, and Utility. Each Category Chest will only contain an item fitting its category, of at least uncommon rarity with a greatly increased chance to hold a legendary item.

Base cost: $60

* Legendary = 20%

## Adaptive Chest

An Adaptive Chest costs twice as much as a Small Chest and can only spawn from the third stage onward. When interacted with, the center portion raises up to reveal a small compartment, which displays and cycles through items at an accelerating rate. Interacting with it again will drop the item currently shown in the cycle. If the player does not choose an item, the 30th one will be automatically dropped. Any regular item can appear in this cycle, including legendary items and equipment, at around the same frequency as a Small Chest.

Base cost: $50

* Pausing the game in singleplayer will also pause the rotation of items in an Adaptive Chest. Therefore, the player can pause and unpause until they find their desired item and hold Interact upon unpausing again.

Item chances:

* Common = 63.06%
* Uncommon = 27.03%
* Legendary = 0.9%
* Equipment = 9.01%

## Rusty Lockbox

The Rusty Lockbox only spawns when a Survivor holds the common item . It does not cost gold to open, and will always contain an uncommon or legendary item.

* At least one Survivor in the party must possess a Rusted Key for it to spawn (guaranteed spawn), but a key is required to open the Rusty Lockbox.
* Every stage, one Lockbox will spawn for each player with that holds any Rusted Keys. The box cannot spawn on Hidden Realms.
	+ Can spawn in the Hidden Realms , , and .
* It is easier to find a Rusty Lockbox while the Teleporter is being charged, because they become locked with orange tendrils like other interactables.

The item chances are the same as for a Large Chest.

## Encrusted Cache

The Encrusted Cache only spawns when a Survivor holds the void item . It does not cost gold to open, and will drop a Void Potential instead of a normal item.

* At least one Survivor in the party must possess an Encrusted Key for it to spawn (guaranteed spawn), but a key is required to open the Encrusted Cache.
* Every stage, one Encrusted Cache will spawn for each player with that holds any Encrusted Keys. The Cache can also spawn in the Hidden Realms , , and .

*See also: Encrusted Key*

## Crashed Multishop "Delivery"

The Crashed Multishop only spawns when a Survivor holds the uncommon item . They act similarly to normal Multishops, but only have two options instead of three. It does not cost gold to open. One item will always be visible, while the other replaced with a question mark.

* At least one Survivor in the party must possess a Shipping Request Form for it to spawn (guaranteed spawn).
* Every stage, one Delivery will spawn for each player that holds any Shipping Request Forms. The delivery can also spawn in the Hidden Realms , , and .
* The rarity of the items are affected by how many stacks of Shipping Request Form the Survivor has at the start of the stage, much like how  behaved before the Anniversary Update.
* Similarly to a normal Multishop, carrying an  will allow both items to be collected.

*For information on rarity scaling, see main page: Shipping Request Form*

## Cloaked Chest

A Cloaked Chest is an invisible chest that can be found in all Environments. Unlike other chests, this one does not have to be purchased. However, it is very difficult to see, being completely transparent, only slightly distorting the background.

* Cloaked Chests get locked while the Teleporter is charging, so try to spot them at this point.
* Keep an eye out for the "Open Cloaked Chest" prompt that appears when walking near the chest.
* Cloaked Chests can be scanned using the .

The item chances are the same as for a Small Chest.

## Drop Chance Bias

When a chest can drop an item from multiple rarities, in order for the game to choose the loot, it does not actually choose a rarity first and then an item within that rarity. Instead, it puts all available items in a weighted list, with each item of a rarity having the weight of the rarity category. This creates a bias towards rarities with more items. For example, for a Large Chest there are 30 uncommon and 26 legendary available drops. This means the weighted list will have 56 items and the chances of getting an uncommon drop are

(

∗

/

(

.2
∗
26
# )
82.1
%

{\displaystyle (.8 \* 30) / (.8 \* 30 + .2 \* 26) = 82.1\%}

.

This behaviour affects all Chests (with the exception of the Crashed Multishop Delivery), Scavenger's Backpack, Shrines of Chance, Void Cradles, Void Potentials, the drops from the Artifact of Sacrifice, and the wave rewards in Simulacrum.

In most cases the actual rarity chances do not differ very much from the expected values, because the number of items within the common, uncommon, legendary, and equipment categories are proportionally fairly similar. Exceptions to this include:

* The Small Healing Chest has (7/4/4) available drops.
* Any Chest or Simulacrum wave reward with void rarity, as there are (5/6/2) available drops.
* Any Simulacrum wave reward that has legendary and boss drops competing.

## Trivia

* As the choices for a Multishop Terminal are completely random, it is possible to have three of the same item appear.
	+ Prior to the *Hidden Realms* Update, it was completely possible to have all three choices be question marks.
* Legendary Chests and Adaptive Chests have collision, unlike all other kinds of chests.
* Prior to the *Hidden Realms* Update, the Rusty Lockbox was hard to spot due to its relatively small size. This update made the Lockboxes easier to spot by making them 50% larger and shinier.
	+ In the *Anniversary* Update, the visibility of Lockboxes was further improved by giving them a glow effect.
* Broken, worn out and rusted chests can be found in the , possibly because the Survivor from Risk of Rain 1 had already been in that area and taken whatever items they held.
