Key

General
Keys are used to unlock chests across Tyria.

Keys are named after the geographic region where they are bought or found (eg. Ascalonian Key and Shiverpeak Key) and can only open chests from that region. The value of keys increase as one progresses in the game, as the value of the items found in chests increases.

Keys of the same type will stack.


 * Note: Keys were implemented at the September 7, 2005 update, and more valuable and rare items are placed inside chests. Also, chests are now randomly placed throughout explorable areas and missions. Prior to that update, chests were not locked and thus keys were not required.

For a list of keys, see Category:Keys.

Usage
Keys may only be used once, meaning players will have to gamble that the items found inside a particular chest will either be useful to them, or have a higher resale value than the key. Because of this risk, when you click on a chest, a confirmation message will popup asking whether you were sure that you want to use a key to open it.

Each member of an exploring party will have to use their own key to open each chest, however, the items found from chests are not shared across the party. A chest opened by a player cannot be opened again by the same player.

Note: Currently, the rarity of items produced by the chests is consistent for the same chest. i.e. If a chest produces a purple item for the first player who opened it, it will produce purple for all who open it afterwards.

Acquisition

 * Bought from merchants in the same region.
 * Random Loot from monsters in the same region.

Value of Loot
While the keys are guaranteed to produce purple items or gold items, it is not guaranteed that these items will be perfect or have maximum statistics. In general, the key is worth more than the item produced from the chest if the item was sold back to the merchant. For example, a Shiverpeak Key is is sold for 600 gold but on average produces items that are worth 200-300 gold at the merchant. The real value is that an item produced by that key could have great statistics and thus sell for multiple platinum to other players in trade. Additionally, identifying the item might unlock upgrades.
