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.

Note that players can use no more than two main servants and one support servant during these exploration quests.

Players may recruit event servants to assist them in conquering the labyrinth. Here is a list of the best servants one can get:

Kama (+100% bonus damage, +50% bonus bond). Yagyu Munenori (+50% bonus damage, +20% bonus bond). Parvati (+50% bonus damage, +20% bonus bond). Scheherazade (+50% bonus damage, +20% bonus bond). Sesshoin Kiara (+50% bonus damage, +20% bonus bond). Mata Hari (+50% bonus damage, +20% bonus bond). Mashu Kyrielight (+50% bonus damage, +5% bonus party bond).

Free and Challenge Quests

Once you complete all the main and exploration quests, and gather all the event items, you can start doing the post-event free and challenge quests.

The free quests include the six floors with rooms, where each room contains additional boss fights and rewards, such as Silver and Golden Apples. Here is a complete breakdown of all free quests:

Floor 1: Tanuki’s Room, Fox’s Room, Dragon Room. Floor 2: Mirage Room, Shiranui Room, Aurora Borealis Room. Floor 3: Dusk Room, Twilight Room, Room of Everlasting Darkness. Floor 4: Falcon Room, Owl Room, Bird of Paradise Room. Floor 5: Plum Hallway, Peach Room, Beauty Under the Moonlight Room. Floor 6: Lady Kasuga’s Ooku.

The final challenge quest becomes available after you complete all main quests. Here’s the list and order of Jochu bosses you will face:

After defeating all six bosses, you will be rewarded with some more Crystallized Ore.
