Unlocking the Dungeon Doors
Final Fantasy XV’s main story will have you hunt down Royal Tombs, which are usually buried deep within creepy dungeons. In some of these dungeons, you might’ve also noticed a few locked doors here and there. If you’ve been wondering how exactly to get these doors open, you can only do so after beating the game.
Once you’ve completed the main story, head to the Hunter HQ just east of the Vesperpool and look for the old lady Ezma. She’ll be sitting on a rocking chair on one of the porches. Talk to her, and she’ll hand over a key, and trigger the side quest ‘Menace Beneath Lucis.’ Now, you’ll be able to open those locked doors and test your mettle in some seriously high-leveled dungeons. Do note that this quest is only accessible once you’ve cleared the main game and all optional dungeons.
