Final Fantasy 7 Remake: How To Complete Corneo’s Secret Stash Side-Quest | Treasure Locations Guide

One of the lengthiest side-quests in Chapter 14, ‘Corneo’s Secret Stash’ takes you on a long journey all across the Undercity. This Final Fantasy 7 Remake quest forces you to find hidden clues, complete optional side-quests, and make progress in the story to find tons of items.

To complete the quest, you’ll need to find Corneo’s Secret Stash Key, which opens strange doors you’ve probably already seen in certain dungeons. The key is only acquired by completing a different side-quest, and you won’t really get any clues. It’s possible to find clues for all the Corneo Stash locations, but it’s found in a random spot — seriously, the stash locations clue is found on the ground in Lookout Point, in the Sector 5 area.

Check the guide below for everything you need to know. We’ve got stash locations, and step-by-step instructions to complete every part of the quest.
