Our complete walkthrough of Pokémon Super Mystery Dungeon follows the story chapter by chapter, from the foreword to the epilogue.

The three phases of the adventure

Serene Village (chapters 1 to 10)

The first part takes place around the village and its school. The dungeons are short and serve as tutorials: items, Looplets and Emeras, Link Moves. These chapters take a long time to play, but they set up the characters, the partner, Nuzleaf, the classmates and Grandpa Carracosta, who will matter later.

Lively Town and the continents (chapters 11 to 16)

Lapras Voyages connect the continents.

In Lively Town, the duo joins Ampharos‘s Expedition Society and discovers the Connection Orb, missions and ranks. The Lapras Voyages open up the Wind Land and the other continents. Meanwhile, legendary Pokémon are turned to stone one after another, and the investigation leads to Revelation Mountain.

Nothingness and the Tree of Life (chapter 17 to the epilogue)

The last part strings together the toughest dungeons and the major battles. Bring a well-trained team, healing items and plenty of Apples. After the epilogue, the post-game opens: evolutions with Xerneas, new dungeons, and recruiting every Pokémon, legendaries included, with the Connection Orb.
