How to unlock secret doors in FFXV dungeons

You can get the key once you’ve beat the game – all you need is patience. When you return to Lucis, you’ll need to go to Risorath Basin, in the northernmost part of the map. Once there, talk to Ezma, the old lady sitting on a porch. Prerequisite to be able to start the quest with Ezma is to beat the game and also finish all the optional dungeons in the game first – Balouve Mines, Crestholm Channels, Daurell Caverns, and Costlemark Tower. She’ll tell you all about the terrible things in those dungeons and give you the dungeon seal key. This will begin the Menace Beneath Lucis quest, which will make you revisit almost all of the dungeons and explore their deeper levels.

The lower levels hide dungeons within dungeons are very high-level – the easiest one is lvl 55, while the hardest is lvl 99. Here’s a full list, along with level requirements:
  • Keycatrich Trench dungeon, lvl 55
  • Greyshire Glacial Grotto dungeon, lvl 65
  • Fociaugh Hollow dungeon, lvl 65
  • Daurell Caverns dungeon, lvl 72
  • Balouve Mines dungeon, lvl 78
  • Steyliff Grove dungeon, lvl 86
  • Crestholm Channels dungeon, lvl 92
  • Costlemark Tower dungeon, lvl 99
The lower layers represent an extra challenge for people who’ve already beaten the game, but want more of it. They’re filled with high level enemies, good loot, a tough boss, some consumables and a shiny new weapon at the end. Finishing the complete set might give you more insight into the history of Lucis, but we wouldn’t count on it. From the look of it, they’re just there to provide end-game content.
