Gameplay

Starting

Twelve Sky does not require the player to pay for a subscription.

Each player can have 3 characters on a single account, with multiple accounts possible. Servers are all Player versus player (PvP) and Player versus environment (PvE). On any server a player may create characters belonging to only a single faction; Guanyin, Fujin or Jinong on any single account.^[8]

To create a new character players must choose between the factions of Guanyin, Fujin or Jinong. Characters from the factions can communicate and trade with only players of their faction, with the exception of a single zone in the game, and form guilds with only their faction. Each faction has a unique distribution of stat points, appearance and skill set available to them and players much choose their play style based on the attributes of the separate factions.

On-Going Gameplay

As the player gains levels, they receive stat points which may be used to upgrade the four stats: Strength, Dexterity, Vitality and Chi. Characters may also form or join guilds. Characters in the same guild have a private chat channel, a shared guild name, guild storage and possibly battle in duels.

Much Twelve Sky play involves questing, which through much of the game's story is told. Some quests are linked by a common theme, with the next quest triggered by the completion of the previous, forming a quest chain. There are also level restricted PvP wars, and special timed wars, such as Heolgo, Chugun Palace, Pagoda.

The game featured a solo- and party-friendly battle system with combat that allowed players to hit their opponents. Factional PvP was also a main focus of Twelve Sky. The game was shut down in April of 2010, and has been succeeded by its sequel, Twelve Sky 2.
