Mastering the UI / Navigating the Game Screen
Important quests, such as main scenario quests or those that unlock game content, are identified by unique icons.
Certain quests offer large amounts of experience points, which are ideal when leveling your character. Others unlock helpful game features such as chocobo companions and the ability to dye equipment. Of course, if you're not certain of which quests to undertake, it is always recommended to continue progression through main scenario quests.
Quest icons may change as you progress, indicating NPCs or places where you may proceed. Should they turn red, it means you do not meet the requirements to do so. In such cases, check the duty list or journal for hints on how to continue. The journal can be found under Duty in the main menu.
Other icons may also appear over the heads of NPCs, indicating the availability of content.
