Gold coins
Gold coins are the primary currency of Tetractys.

Players can win gold coins:
 * As a reward for completing an easy-peacy mission
 * As a reward for winning a battle mission
 * As a reward at the end of a daily tournament between players, if the balance is positive
 * As a prize for participating in a tournament or event, based on their final ranking
 * As a gift for logging into the world of Tetractys every Sunday
 * As a special gift for every time they log into the game
 * As a gift for increasing the members of their family
 * As a reward for completing a work
 * By selling unwanted items (which they possess) to The General Store
 * By re-purchasing artefacts
 * By crossing the boarders to another realm: Every 100 levels players receive a bonus equal to a percentage of the total amount of coins which they possess at that particular time

Gold coins can be used:
 * For the development of a player’s main attributes
 * For purchasing equipment, tools, stones and pieces of collections
 * For discovering new technologies
 * For purchasing artefacts
 * For paying the balance at the end of a daily tournament between players, if the balance is negative
 * For supporting the guild and its goals

Dies
Dies are the second currency of Tetractys, significantly more rare than gold coins and hard to find. They were created by Dim-bo-o, and were initially purposed to serve as propaganda for global peace. Dies are basically stone seals, made from a rare mineral; when used as a stamp into a surface, dies impress a sign (a sign that Dim-bo-o hoped would become a world symbol for peace), surrounded by the inscription PEACE. Unfortunately, the Tetractians have not quite understood the idea of dies and therefore see them as a peculiar and rare object, a well-forged remain of an ancient civilization, and not as stone seals.

Due to this misunderstanding, dies have become very valuable, although they're not a rare item.

Players can win dies:
 * By logging into the game every Friday (10 dies awarded)
 * As loot from missions, battles and practice-fights between players
 * As a prize for participating in tournaments and events, based on their final ranking
 * At random, by logging into the game on a daily basis (these chances are increased as players level up)
 * As a gift for increasing their family members
 * By visiting The Black Market
 * By crossing borders: Every 100 levels players receive a bonus equal to a percentage of the total amount of dies which they possess at that particular time

Dies can be used to improve the quality of a player’s journey; to facilitate players when time is pushing; to give players the right to claim the identification of other players, as well as the ability to receive updated equipment or rare items of great power.
