To unlock the Dawntrail job quests in FFXIV, you generally need to complete the Dawntrail main scenario questline far enough to reach the role/job quest unlock point, then speak to the quest NPC in Tuliyollal.

What to do

  1. Progress the Dawntrail MSQ until you clear “The Feat of Pots”.
  1. After that, pick up “Uncouth Customers” from Br'uk Evu in Tuliyollal at X:12.4, Y:14.5.
  1. That unlocks the role quests for Dawntrail, which are the job-quest-style progression for level 90+ content.

Important note

  • In FFXIV, many unlocks are tied to MSQ progress , not just your character level, so being level 90/100 alone is not enough.
  • For later Dawntrail quest chains, some finales also require completing all related role quests first.

If you mean old job quests

If you meant the earlier class/job quests from ARR through Endwalker, those are usually unlocked by reaching the required job level and going to the appropriate quest-giver for that job; they are separate from Dawntrail’s role quests.

If you want, I can map out the exact unlock chain for your specific job, like Viper, Pictomancer, tank, healer, melee DPS, physical ranged DPS, or caster.
