Unlock "Cave of the Seven Stars" Dungeon
Beat the game once, reload your save and enter the left door up the stairs after the final save point which allows you to fight the Undying Dragon. Once you beat the dragon, you receive the Darkness Ring. Go back to the Colosseum in Tatroi and go to the end of the left hallway on the first floor. Use the Darkness Ring on the Glyph in the wall to uncover the secret entrance to the dungeon.

Unlock Wandering Dungeon
Defeat Gabriel Celeste at the end of the Cave of the Seven Stars. After that, take the elevator in En II down to the Old Road to Sanctuary and speak to Barago. Barago will then take you to the entrance. Monsters here appear as shadowy zombies, so you never know which enemies you'll be facing in combat, and each floor is randomly generated every time you step in. There are no save or restoration spots, and the final boss of this dungeon is 20 floors in. If you leave the dungeon, the floors are randomly generated again, and you must start over. After defeating the Ethereal Queen on the 20th floor the dungeon goes on for as many floors as you like, simply repeating the bosses of the 19th and 20th floors.
