Players must be level 13 to join and be invited to a guild. Upon leveling, a tutorial will appear instructing the player on how to apply to one or more guilds.
Players may apply to as many guilds as they wish regardless of the guild's population provided you are currently not in one. The officers and higher ranks will then decide to accept/reject the requests from the Levy button on the Members tab.
Players must wait 24 hours after they leave a guild to join another guild or create a new one. Players may immediately join another or create a new guild if they are kicked from a guild by a guild officer, assistant guildmaster, or guildmaster. You can prevent this by buying a "Covenant Emancipation" Scroll (395 balens).
Leaving a guild will cause you to lose all contribution points and temporarily lose the purchased guild skills. When the player joins another guild, they will get the guild skills bonuses back within the limits of the new guild's skill tower.
