Secret Dungeon - Mysterious Unison
In the last desert area in chapter 7, head east three times to reach the oasis. There will be an item there as well as a large door. After the battle with the Ruined Body (2nd to the last boss), you will receive a Hero's Crest. Use it on the door to open it and unlock the archievement.
