The Infinite Tower is a late-game challenge added in Sailor Piece Update 7.0.
It lets players fight endless waves of enemies and earn powerful rewards.
To enter the tower, you must use a Tower Key. One key is consumed every time you start a run.
The mode is designed for endgame players only, so make sure you meet the level requirement before trying to enter.
Important requirement: You must be at least Level 8,500 to access the Infinite Tower.
If you meet the requirement, the tower becomes one of the best ways to farm rare items, tokens, and stat boosts in Sailor Piece.
What Is a Tower Key in Sailor Piece?
A Tower Key is the item required to start a run inside the Infinite Tower (Sailor Piece).
Each time you open the tower portal, 1 Tower Key is consumed.
Because the tower gives valuable rewards like Tower Tokens, gems, and exclusive gear, players usually farm multiple keys before starting long runs.
How to Get Tower Keys
Tower Keys can drop from any enemy in the game.
However, the drop rate is higher when defeating stronger enemies and bosses.
Best places to farm them include:
- Lawless Island (Sailor Piece)
- Ninja Island (Sailor Piece)
These islands have higher-level enemies that respawn quickly, making them ideal for farming keys.
Focus on defeating large groups of enemies to increase your chances of getting drops.
How to Farm Tower Keys Faster
If you want to collect keys quickly, use farming builds that clear enemies fast.
Helpful strategies include:
Use strong AoE attacks
Area-of-effect abilities allow you to defeat multiple enemies at once.
Increase your Luck stat
Luck affects item drop chances. Titles, skill tree upgrades, and accessories can improve it.
Enable AFK farming tools
Turn on options like Auto Skill and Auto Haki while farming mobs.
Equip your best gear
Use your strongest Sword, Spec, Accessories, Artifacts, and Runes to clear enemies faster.
The faster you defeat enemies, the faster you will collect Tower Keys.
How to Use a Tower Key
Once you have a key, follow these steps to start a tower run.
- Travel to Tower Island (Sailor Piece).
- Find the tower NPC in the center of the island.
- Interact with the NPC.
- Click Spawn to open the portal.
Starting the run consumes 1 Tower Key.
How the Infinite Tower Works
Inside the Infinite Tower, you fight through increasingly difficult floors.
Each floor contains waves of enemies or bosses. Clearing them unlocks the next floor.
Rewards are given for defeating enemies and reaching higher floors.
Common rewards include: EXP, Gems, Money, Tower Tokens
The higher the floor you reach, the better your rewards will be.
Infinite Tower Debuff System
The tower becomes harder as you progress.
Every five floors, a random debuff is applied to all players.
These debuffs can include: Reduced health, Lower damage, Lifesteal restrictions, Other combat penalties.
Difficulty increases at certain milestones:
- After Floor 50: two debuffs are active
- After Floor 100: three debuffs are active
Because of this system, survival and strong builds become more important the higher you climb.
Daily and Seasonal Rewards
The tower offers two types of reward systems.
Daily Rewards
Daily rewards depend on the highest floor you reach in one day.
If you push further each day, your daily reward becomes better.
Seasonal Rewards
Seasonal rewards track your progress during the event period.
Even if you do not reach record floors every run, your total points still increase over time.
This system rewards consistent tower runs.
Infinite Tower Leaderboard
The tower also includes a leaderboard.
Players who reach the highest floor among all players will rank at the top.
High leaderboard placements often indicate the strongest builds and best teams in the game.
Tower Tokens Explained
The main currency earned inside the tower is Tower Tokens.
These tokens are used to buy exclusive upgrades and equipment.
Important rule:
Tower Tokens cannot be traded.
They can only be earned by playing the Infinite Tower.
Tower Token Stat Upgrades
Tower Tokens can permanently improve your character through stat upgrades.
Available upgrades include: Damage, Critical Damage, Critical Chance, HP, Luck.

Void Empress Title
This title has a very rare drop chance when clearing floors.
When equipped, it provides:
+77.5% damage boost

Best Strategy for Infinite Tower Runs
The most efficient way to farm tower rewards is to push as many floors as possible in a single run.
Running the tower with a team usually works better than solo runs.
A strong group can clear floors faster, survive debuffs longer, and collect more Tower Tokens per key.
This strategy helps you maximize rewards while using fewer Tower Keys.
