Role quests are a big part of Final Fantasy XIV, giving you access to new content and skills to learn for your character. They work a little differently for the Dawntrail expansion, and the way you unlock them makes them easy to miss.
FFXIV Dawntrail Role Missions Ranged DPS Level 100
They unlock as you progress through the expansion; if you’re not careful, you can easily breeze past them. You’ll have to put in some work to get to this point in the game, and they’re not mandatory. Instead, you can complete them after you finish the Dawntrail campaign, but you don’t want to wait forever to do them in FFXIV.
Role Quests become available to your Final Fantasy XIV character as you progress through the Main Scenario Quests in Dawntrail. After you complete The Feat of Pots, which is around level 92-93, your Role Quest will now be available for you to work on at your leisure. You do not have to complete your Role Quest to continue playing through the main story, so don't feel obligated to do so right away.
You can start the Role Quest by first completing Uncouth Customers in Tuliyollal. Speak to the NPC Br'uk Evu, who you may have encountered while completing other quests in the Main Scenario Quests. He is located at the coordinates (X:12.5, Y:14.6). This is a required first step for all Final Fantasy XIV players, and after it is completed the following quests will become your Role Quest.
