Ooku Revival is an annual event in Fate/Grand Order that puts players into the labyrinth of the Edo Castle in Japan, where they need ot fight a hefty number of bosses.

This event can be quite confusing to new players, so our guide will provide you with a clear guide on how to complete Ooku Revival event in Fate/Grand Order, including a list of all rewards in the end.

Main Quests and Explorations

Complete Main Quests

The Ooku Labyrinth has a straight path that covers the main quest, and many divergent paths leading to various challenges. The more of these explorations you complete, the more challenges you unlock, gaining more and more rewards in the process.

The main quests include the following chapters:

  • Prologue.
  • Acts 1-10.
  • Final Act.

Beginning from Act 2 you will start encountering NPCs, bosses to fight, and earning completion rewards such as Saint Quartz. Once you complete the Final Act, you will be rewarded with Crystallized Ore.

Complete Exploration Quests

Once you reach your first junction in the labyrinth, you can use your Osuzu Lantern to unlock the first diverging path. These quests are optional, but offer lots of valuable rewards.

The exploration quests include the following paths:

  • Levels 1-5.
  • Mystery Spot.

Each Level consists of crossroads that have left and right passages. Most passages contain boss fights and rewards, but not all of them. Once you reach the dead end of any one passage, simply return to the junction and try another route.

Once you complete Act 8 of the main campaign, you will gain access to the Mystery Spot, which includes five floors worth of additional exploration quests.
