"Since an unknown accident a long time ago, this city has been closed. Rumor has it that a secret experiment happened here. Even though it's been a long time, it still remains restricted."
"You can acquire Options Points for Option Recontracts."
Closed City is a special dungeon and the only way of obtaining Option Points while exploring (with the exception of special events). The first area of the dungeon is unlocked when a player reaches Level 20, although contractors of that level might not be able to clear the dungeon due to its difficulty.
Each area of the dungeon has a specific boss and gives a different amount of Option Points based on it's difficulty. Since the dungeon is hard to clear and the Light Cost is high, it is recommended that the player always have enough FP for retries when exploring.
- Fountains of Light do not appear on these dungeons.
- High chances of finding Powerful Devils or Boss Battles while exploring.
- High chances of getting Devil Gaze jackpots, which means players can occasionally get Devil Perfumes by exploring this dungeon.
