You unlock The Twinning immediately after finishing the Shadowbringers main scenario up to “The Final Gasp.” The dungeon is opened by the quest “By the Time You Hear This” in the Crystarium, so the answer is 0 quests after The Final Gasp if that’s the point you mean.

Quick Scoop

  • Prerequisite: Finish the Shadowbringers main story.
  • Unlock quest: By the Time You Hear This.
  • Location: Crystarium, from Bethana.
  • Practical answer: You do not need to do a long chain after The Final Gasp first; the unlock is effectively right after completing that story point.

Tiny caveat

Some guides phrase it as “after you beat the main story,” which can make it sound like there are extra quests in between. In practice, the dungeon’s unlock quest is tied directly to finishing the relevant MSQ milestone.
