Fishman Island New Season ‘Abyss Citadel’ is now live! Mix and match modifiers freely, climb the season rankings, and define your own difficulty! Come and face the ultimate trial meant for the strongest!

⚓ The Abyss Citadel Challenge Begins Now!

The Abyss Citadel is composed of multiple floors. Each floor contains several Watchtowers (stages). Captains must challenge and clear all stages on the current floor in sequence before advancing to the next floor.
As you ascend to higher floors, enemies will gain higher HP, Attack, and overall strength. However, the drop rewards and clear points will increase accordingly!

⚠️ Challenge Attempts: Each floor has an independent number of challenge attempts.Each failed attempt will consume a challenge attempt, while a successful clearance will not consume any.
If your remaining attempts are exhausted, you will be unable to continue challenging the remaining stages until the Citadel progress resets. Upon reset, you must restart the challenge from the first stage of your current floor.

Normal Mode Vs. Infinity Mode: What’s the Difference?

📦 Normal Mode

There are 10 floors in total, each offering rich rewards upon clearance! When Captains challenge stages in Normal Mode, rewards for that floor will accumulate. You can only claim the accumulated rewards after clearing all stages on your current floor. If you reset your modifiers before completing all stages on the current floor, you will lose all accumulated but unclaimed rewards for that floor.

💡 Hint: The higher the floor, the more fixed modifiers there will be, and the difficulty will gradually rise. Captains will need to adjust their lineup, character placement, and team synergy based on the effects of these fixed modifiers.

⚔️ Infinity Mode

● Unlock Requirement: Clear Floor 10 of Normal Mode to unlock Infinity Mode.
● Custom Modifiers: In Infinity Mode, you can custom-select the modifiers for your current run. Different modifiers introduce different challenge difficulties and grant extra point bonuses!
● Exclusive Rewards: First-time clearance of each floor in Infinity Mode awards Exclusive Badges, which can be exchanged for rare rewards in the Citadel Shop!
💡 Hint: Infinity Mode supports repeated challenges of unlocked stages. Captains can continuously tweak their lineups, modifier combinations, and combat strategies, retrying as many times as needed until achieving a satisfying clear point.

Challenge Points & Season Rankings

🏆 Season Rankings

The system will record the highest historical point achieved by all participating Captains during the season. When the season ends, ranking rewards will be distributed based on these highest historical points.

📊 Challenge Points

Each time you completely clear a floor during the season, the system will point your performance based on the difficulty of the Citadel run.
● The higher the floor cleared, the higher your Stage Points.
● The harder the modifiers selected upon clearing, the higher your Challenge points.

Challenge Points = Stage Points × Total Modifier Multiplier

🌟 Important! Mix and match more diverse MOD combinations to earn higher points and push for the top of the Season Rankings!

About Modifiers

📌 Fixed modifiers

In Normal Mode, new fixed modifiers will be added every few floors. Fixed modifiers apply to all stages within that specific floor. The higher the floor, the greater the number of fixed modifiers, steadily increasing the challenge difficulty.

⚙️ Custom modifiers

Different modifiers bring distinct combat effects and provide extra point bonuses. The more modifiers you select, the higher the challenge difficulty, but the more points you will receive upon successful clearance.
In Infinity Mode, clearing higher floors unlocks a greater number of selectable modifiers. As the floors increase, Captains can combine more modifiers to secure higher points and storm the Season Rankings!
