question about unlocking job

[Niwashi]

It's at level 30, not level 15. Once you get one of the ARR combat classes up to level 30 and finish its level 30 class quest, there will be another quest offered by someone at the class's guild hall to unlock the corresponding job. (Depending on the class, sometimes it's the guildmaster, sometimes the receptionist. Just look for the quest icon with the plus sign indicating it's a significant unlock.)

You might still find some outdated information online indicating you need one class at 30 and another at 15. That used to be the case, but no longer is. Now the requirements are just:

• The base class to level 30
• Complete the level 30 class quest
• Have completed at least up through Slyph Management in the Main Scenario

p.s. The unlock quest will start at the class guildhall, but send you somewhere else. That somewhere else is where you pick up the subsequent job quests.

As a lancer, the quest you want to unlock your job is Eye of the Dragoon. You get it from Ywain (the lancer guildmaster) and he'll send you to the Observatorium in Coerthas Central Highlands to talk to Ser Alberic. You'll then go back to Ser Alberic for subsequent job quests.
