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.


 * 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.

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.
