Keys

There are many different kinds of keys that can be used in Hidden City, there are keys to open doors, enter locations, mini-games, and to unlock treasuries.
All of these keys have one thing in common which is they open the different types of City Treasures that can be found on the map.

## Skeleton Keys

Skeleton Keys can be earned in all locations except the event location, players will earn two per play and previous items leftover to enter an event location become Skeleton Keys.

## Treasures of the Fog

Juliette:

Mon ami, when the fog cleared I spotted some items in the square. If you bring them to me we can see what they are.

## Gift from the City

Cardsharp:

Well met on this fine day in the City of Shadows, buddy. You see that? The Fog is almost gone and...

Oh yes, yes.. I can see the glitter on chests and artifacts that it brought from the depths of the City. Want to take a look at it?

## Key (under construction)

Only one key is required for this chest.

This makes the chest one of the simplest to open, and should often be collected by players that have the time.

Alternatively, the key is priced at 3 rubies.

## City's Treasures Keys

Nine keys are required for this chest that has relatively little reward in comparison.

The keys are priced at 9 rubies, being valued at 1 ruby per key.

But it may take many monster fights to gain 9 keys.

## Survival kit Key

An essential part to every explorer is a kit for survival, but the player has located a traveler's one that is locked. The key oddly uses the same appearance as the one used to open more Monster Treasury Chests. To open this chest, a player should ignore anomalies in the city until this chest appears. Keys can be gained by searching a location with an anomaly, or by expelling them.

### Notes:

* All keys, regardless of the amount gained, or when the chest appeared, will disappear at the end of the day. The goal is to try open the desired chests within that single amount of time. It is possible for the same chest to appear multiple times in a day, only after it has been opened.

* If a player wishes to unlock a chest via coins, a player will have to use rubies instead unless it is the Exploration Chest (the one that requires coins to unlock it).

* There is also a coin pile players are able to unlock via coins but if wanting to unlock anything else without using the keys they will need to use rubies (the in game currency besides coins). A player first needs to click on the chest on the map in order to pay with rubies as they are not available in store.
