Have difficulty getting beyond the first few floors of the Sailor Piece Infinite Tower? You're not alone. The Infinite Tower is the biggest endgame addition the game has ever seen, and most players are entering with the wrong build, farming keys from the wrong location, and spending Tower Tokens on the wrong items first. This guide fixes all of that.
What Is the Sailor Piece Infinite Tower
The Infinite Tower is an endless survival gamemode that was included with the Massive Update on March 25, 2026. It introduced three new islands, two new swords, a new race, a new clan, and an increase in the level cap to 13,000, thus making it the biggest content release to date since the game's launch.
The essence of it is simple: get into the tower, shoot off the enemies, survive the boss wave every five levels, and go as far up as possible. The higher your floor, the better your Tower Token rewards per run. There is a global leaderboard that tracks each player's highest floor, which resets periodically.
Requirements to Enter the Infinite Tower
Before you can access the Sailor Piece Infinite Tower, three requirements must be met:
- Level 8,500 minimum — this is a hard endgame gate
- 1 Tower Key — consumed on entry, one key per run
- Tower Island access — travel via warp or portal, no quest gate required
Once on Tower Island, locate the Infinite Tower NPC in the center of the island, click Spawn, and the portal opens. Notably, auras now work inside the tower following a hotfix on March 25. Activate yours before entering.

How to Get Tower Keys Fast in Sailor Piece
Tower Keys drop randomly from any NPC across the game, but drop rates are meaningfully higher on the two new high-level islands added in the same update.
Best farming location:
| Location | Enemy | Level | Method |
| Lawless Island | Arena Fighter | 12,000 | AFK with auto skills |
| Ninja Island | Ninja | 11,500 | Active or AFK |
Arena Fighters on Lawless Island are the superior option. Higher level means slightly better drop rates, and the spawn density makes AFK farming straightforward. Turn on Auto Haki in settings (a new quality-of-life addition from the update), stack Luck boosts, and run an AoE build. A single overnight session comfortably produces 20 to 50 Tower Keys, which is enough for multiple serious tower runs.
How the Infinite Tower Works: Floors, Debuffs, and Drops
Every five floors is a boss floor. Clear it to progress. The debuff system is what separates casual runs from optimized ones. Random negative effects stack progressively the deeper you push:
| Floor Range | Active Debuffs |
| Floors 1–50 | 1 random debuff per boss floor |
| Floors 51–100 | 2 random debuffs per boss floor |
| Floor 101+ | 3 random debuffs per boss floor |
Debuffs include reduced damage output, disabled lifesteal, and other negative effects that change each run. Because they are random, survivability stats, defense, HP, and lifesteal when active matter more than pure damage output at higher floors.
sailor piece infinite tower drops scale with floors cleared per run:
- Tower Tokens (primary currency, the main reason to push high)
- EXP, Gold, and Gems
- Race, Clan, and Trait rerolls
- Chests ranging from Common to Mythical
- Secret Runes, Radiant and Primordial, have a very low drop chance exclusively inside the tower

Best Build for Pushing High Floors
Here is what actually works inside the Sailor Piece Infinite Tower:
Prioritize in this order:
- AoE damage — single-target builds fall apart against wave-heavy floors
- Lifesteal — essential for sustaining through debuff floors where healing is otherwise unavailable
- Crit rate and crit damage — multiplies AoE effectiveness significantly at scale
- Defense and HP — increasingly important past Floor 50 when two debuffs stack simultaneously
Recommended builds by platform:
- PC: Gojo V2 paired with Anos delivers the best combination of AoE clearance and survivability
- Mobile: Gilgamesh is the most consistent option given mobile control limitations
Team runs clear floors meaningfully faster than solo attempts, specifically because boss floors become significantly harder past Floor 50. If you have alliance members at the endgame level, coordinate entry times and run together. Your personal Tower Token yield per key spent increases substantially in team play.
How to Get the Abyssal Empress Sword Fast in Infinite Tower
Abyssal Empress is one of the two new swords added in the Massive Update and is immediately one of the strongest options for Sailor Piece Infinite Tower farming due to its wave-clear moveset.
Fastest method, no RNG involved:
- Farm Tower Tokens via AFK runs on Lawless Island for keys, then push the tower
- Accumulate 4,000 Tower Tokens
- Purchase directly from the Tower Shop NPC on Tower Island
Alternative: Abyssal Empress has a very low chance of dropping directly as a boss reward inside the tower. Do not rely on this; the drop rate makes it genuinely unreliable as a primary farming strategy. The 4,000 Token purchase is reachable within one to two days of dedicated AFK farming and is the only consistent method.
Abyssal Empress moveset:
| Move | Effect |
| M1 | Purple and red slash combo |
| Z | 3 continuous low-cooldown slashes |
| X | Forward slash plus void blast |
| C | Dual slashes plus large AoE |
| V | Multi-slash cutscene plus void burst |
| F | Domain slash plus flower petal AoE is the highest damage move |
The F move is particularly strong for boss floors. The domain slash covers a wide area and hits multiple times on contact.

Infinite Tower Shop: What to Buy First
Not all Tower Shop items are equal. Here is the correct purchase priority based on what actually accelerates your progression fastest:
| Priority | Item | Cost (Tokens) | Why |
| 1 | Abyssal Empress Sword | 4,000 | Immediate DPS and wave-clear upgrade |
| 2 | Abyssal Outfit | 900+ | +105% DEF, -15% DMG taken, +80% DMG massive survivability boost |
| 3 | Secret Chest | 600 | High-value random rewards, best token-to-value ratio |
| 4 | Purple Flare Aura | 1,200 | Shop exclusive items unavailable anywhere else |
| 5 | Aura Crate | 1,200 | Random aura is worth it after securing the above |
| 6 | Mythical Chest | 75 | Stack these once the core items are secured |
| 7 | Race / Trait Rerolls | 4 each | Cheap, useful for building optimization |
The permanent stat upgrade shop on Tower Island is separate from the Tower Shop. Prioritize damage and crit upgrades first; these scale multiplicatively with your existing build and meaningfully increase your Tower Token yield per run.

FAQ
My Tower Key disappeared, but I never entered the tower — what happened?
Tower Keys do not get used when you get to the 1st floor, but when you click Spawn to the Infinite Tower NPC. In case the portal did not open with key consumption, reconnect to the server as soon as possible, and also check your mailbox - the developers have since made hotfix releases to fix bugs in the entry points, and usually moved the reward giver back to players over the compensated mail.
Is it worth spending Tower Tokens on Race Rerolls before buying the Abyssal Empress sword?
No. Secure the Abyssal Empress at 4,000 tokens and the Abyssal Outfit first; both directly increase how many floors you clear per run, which means more tokens per key spent. At the cost of 4 tokens each, racial rerolls are sufficiently affordable to purchase in large quantities later on that they do not significantly slow down your item development.
How can you get to Level 8,500 so that you can access the Infinite Tower the fastest?
Lawless Island Arena Fighters at Level 12,000 are currently the best EXP source in the game, in the same location you farm for Tower Keys. Stack EXP boosts from codes, run Auto Skills and Auto Haki, and use an AoE build.
