I was given a key to a treasure box in a labyrinth called the Valley Spring. Can you bring me what's inside?

Treasure on my Mind (Etrian Odyssey IV)Edit


Quest GuideEdit

If you're not at a level where you can defeat the Furyhorn and just go a more direct route to the quest box at B/2-4/5, there is a hidden passage way you can take at C/2-4/5 just a ways away from your Skyship. This grants you back door access to the locked Golden box to obtain the item in question.


  • Item: Speed Hammer
  • Exp: 3500
  • Bonus: Old Breastplate (take it to Berund Atelier to get the Pure Plate)
