Curio

During expeditions there is a chance of encountering Curios. There is a chance of a good or bad event from touching a Curio. Supply items can be used on curios, such as a torch or a key, to favorably alter the chances of getting a good or bad event.

Location
Curios can be found either inside rooms or corridor segments. Different locations contain different kinds of curios, but some varieties of curio are found throughout all types of dungeon. Each room may only contain one curio, while corridor segments can contain more than one curio. Differently from obstacles, curios do not prevent passage when not activated, and it is thus possible to leave them be to minimise risk, especially if there is a lack of correct provision items to trigger their benign effects.

Interacting with Curios
Once the party enters the room or segment that contains the curio, it can be clicked to activate a prompt. Through the prompt, the curio can be activated directly or with the use of a provision item: curios will react differently to certain items. Normally, the use of the correct provision item will trigger a positive effect, removing the chance of negative effects occurring, but there are exceptions.

Some curios grant loot upon activation. There is a fixed pool of items that can be looted by specific curios, but additional loot due to a low light level will be calculated separately and can thus be dropped even by curios with very specific loot drops.

Many curio effects such as stress infliction or heal, damage, the application of buffs and debuffs or the gain or removal of a Quirk affect individual heroes. The affected hero is always the one currently selected at the moment of activation. It is advisable, upon activating risky curios, to select a hero with good resistances or one that could potentially be affected by the negative effects without endangering the expedition.

Update: currently, as diseases have been reclassified as something different from a quirk, curios no longer cure diseases (i.e. Eerie Coral with Medicinal Herbs did not cure anything on a character with no quirks with the runs disease).

Forced Interaction
Sometimes, because of a Quirk the hero may have, they will interact with a curio without the player's consent. This is determined through Curio Types, with certain quirks respond to i.e. a hero with Bloodthirsty may interact with a Dinner Cart or Mummified Remains automatically when approaching it because of their shared "Body" typing. This can be dangerous since they will never use an item on their own when doing this, so there is a very real chance they will cause permanent damage to themselves. In addition a few of these quirks will also compel your heroes to steal the items that are looted, preventing the player from ever getting them.

However, there is a brief window of time during a forced curio interaction where the player may still use a supply item. The appropriate supply item for the curio must be right-clicked from the party's inventory after the hero indicates that they are about to perform a forced interaction but before the interaction resolves. This will yield the same results as if a non-forced curio interaction had been performed using the supply item. As this window of opportunity is very small, success often requires having the inventory window open beforehand, along with good knowledge of your party's quirks.

While usually the only way a forced interaction will occur is because of a negative quirk, the disease Tapeworm and some afflictions can also cause a forced interaction.

Below is the list of quirks that force interactions, along with their type, chance of interaction and whether or not the quirk will inspire theft.

Quest Curios
Some quests require the player to activate curios with special items given at the start of the quest or retrieve special items from these curios. Unlike other curios, these curios can be found in either corridors or rooms (unless otherwise mentioned).

Retired Curios
These curios were once part of the game, but are currently unused.
