Sailor Piece's Infinite Tower is the game's premier endgame challenge, introduced in Update 7.0. It pits high-level players against endless waves of increasingly dangerous enemies across an unlimited number of floors, rewarding them with exclusive gear, currency, and stat upgrades that can't be obtained anywhere else. Getting in requires preparation, and climbing high demands a finely tuned build.
Quick answer: You need to be at least Level 8,500 and possess a Tower Key to enter the Infinite Tower. Teleport to Tower Island, speak to the Infinite Tower NPC, and click Spawn to open the portal.
Infinite Tower Entry Requirements
Two conditions must be met before you can step through the portal. First, your character level must be 8,500 or higher. Second, you need at least one Tower Key in your inventory — each key is consumed when you spawn the portal, so you'll want several on hand before you start grinding runs.
How to Get Tower Keys
Tower Keys drop from defeated enemies. While any mob or boss across all islands has a chance to drop one, higher-level enemies offer a somewhat better drop rate. Ninja Island and Lawless Island are the two most popular farming spots because their enemy density lets you chain kills quickly. Equip a build with strong AoE damage so you can wipe out groups of Ninjas or Arena Fighters in just a few hits. The drop rate is reasonable enough that a focused farming session should net you a comfortable stockpile.
How the Infinite Tower Works
After spawning the portal on Tower Island and walking through it, you enter a floor-based gauntlet. Each floor throws waves of enemies at you, and every five floors, you face a boss that acts as both a checkpoint and a major reward source. The mode can be played solo or with a party — bringing allies makes the waves significantly more manageable.
The twist is the debuff system. Every five floors, a random debuff is applied to all players in the run. These penalties can reduce your damage output, limit your dodge count, restrict lifesteal, or cut your maximum health. The debuffs replace each other in the early floors, but the stacking gets brutal as you climb higher.
| Floor Threshold | Debuffs Applied | Additional Notes |
|---|---|---|
| Floors 1–49 | 1 random debuff every 5 floors | Previous debuff is replaced |
| Floors 50–99 | 2 random debuffs every 5 floors | Enemies become noticeably tougher |
| Floor 100+ | 3 random debuffs every 5 floors | Enemies gain significantly more health |
Active debuff effects are displayed in the bottom-left corner of the screen, so you can always check what's working against you.
Tower Tokens and How to Spend Them
Clearing floors earns you EXP, Gold, Gems, and item drops along the way, but the most important currency is Tower Tokens. The number of tokens you receive at the end of a run scales with how many floors you managed to clear — pushing deeper means a bigger payout. Tower Tokens cannot be traded between players; they can only be earned inside the tower.
Tower Tokens have two uses on Tower Island. You can spend them at the Infinite Tower Upgrades NPC to permanently boost your Damage, Critical Damage, Critical Chance, HP, and Luck stats. Alternatively, you can visit the Infinite Tower Merchant to buy gear, rerolls, chests, and other items from the Tower Shop.
Full Tower Shop Price List

| Cosmetic Crate | 1,500 | Random cosmetic item |
| Aura Crate | 1,200 | Random aura |
| Purple Flare Aura | 1,200 | Specific aura purchase |
| Abyssal Outfit | 900 | +105% DEF, +80% DMG, 15% less DMG taken |
| Secret Chest | 600 | High-tier loot chest |
| Mythical Chest | 75 | — |
| Legendary Chest | 30 | — |
| Epic Chest | 15 | — |

The three marquee rewards are the Abyssal Empress sword, the Abyssal Outfit, and the Purple Flare Aura. While these items can technically drop during tower runs, the drop rates are extremely low. Saving up tokens and buying them outright from the shop is far more reliable. All Tower Shop items are permanently available, so there's no rush if your build isn't ready yet.
Build Recommendations for Climbing Higher
Reaching floor 50 and beyond requires more than raw level. Your build needs to be optimized across several dimensions to handle the escalating debuffs and enemy health pools.
Step 1: Max out at least three primary stats and fully complete your Skill Tree before attempting serious tower runs. Being at or near the level cap is effectively mandatory for floors above 50.
Step 2: Equip your strongest sword, melee weapon, and devil fruit. DPS and AoE coverage are the two most important combat traits for clearing waves quickly before debuffs stack up.
Step 3: Slot in accessories, artifacts, runes, and titles that boost damage, critical chance, critical damage, and defense. Lifesteal is especially valuable because several debuffs target your survivability directly.
Step 4: Make sure your race and clan are high-tier rarities. The passive bonuses from top-tier races and clans provide meaningful stat edges that compound over dozens of floors. If yours are suboptimal, use Trait Rerolls, Race Rerolls, and Clan Rerolls — all of which are available in the Tower Shop itself.
Is the Infinite Tower Worth Farming?
For endgame players, the Infinite Tower is currently the single best source of exclusive gear, stat upgrades, and reroll items. The token-based upgrade system at the Infinite Tower Upgrades NPC provides permanent stat boosts that aren't available through any other method, and the shop's Abyssal Empress and Abyssal Outfit are among the strongest items in the game. If your build isn't strong enough to push past the first few bosses, spend time farming better equipment and leveling up first — entering underprepared just wastes Tower Keys. Teaming up with other players is a practical way to stretch each key further while you're still gearing up.
