Updated: March 26, 2026 
Sailor Piece just dropped a massive update, and one of the coolest things in it is the Infinite Tower. It is a brand new game mode that was created for players who want a real challenge. If you have already done most of the content in the game and want something that pushes your skills, this is exactly what you are looking for. Here is the complete Sailor Piece Infinite Tower mode guide.
What Is the Infinite Tower?
The Infinite Tower is an endless mode that sits on the new Tower Island, where you fight through floors one by one. Each floor has different enemies, and the higher you go, the harder things get. There is no finish line here. You just keep going for as long as you can survive. You need to think about your build and your strategy if you want to make serious progress. The enemies scale up fast, so going in without a plan will get you stuck pretty early.
To get into the Infinite Tower, you need to be player level 8,500 and have a Tower Key. You can farm these by killing NPCs on Lawless Island. Just grind the Arena Fighters NPCs there, and the keys will drop as you go. The drop chance is low, though, so do not expect the key to show up after a few kills.
Make sure you have a decent stock of them before heading into the tower, because you will want to run it multiple times to build up your coin count.
Sailor Piece Infinite Tower Mode Guide
The Infinite Tower does not just throw stronger enemies at you. It also adds random debuffs on certain floors to make things even harder. The debuffs kick in on boss floors, which happen every 5 floors. Here is how the debuff system works as you climb higher:
| Floor Range | Number of Debuffs |
|---|---|
| Floor 5, 10, 15... (every 5 floors) | 1 random debuff |
| Floor 51 and above | 2 random debuffs |
| Floor 101 and above | 3 random debuffs |
These debuffs are random each time, so you cannot fully predict what you are walking into. That is what makes this mode so replayable. Every run can feel different depending on what the game throws at you.
Sailor Piece Infinite Tower Leaderboard and Rewards
The Infinite Tower gives you Tower coins for every floor you clear. These coins are the main reward, and you will need a lot of them if you want to unlock everything the Tower Shop has to offer. There are two types of rewards in the Infinite Tower:
- Daily Rewards are based on the highest floor you reach in a single day. The further you get before the day resets, the better your daily payout.
- Seasonal Rewards work differently. You collect points over a longer event period, so even if you are not breaking records every day, you can still build up your seasonal total over time.
There is also a leaderboard tied to the Infinite Tower. If you can reach the highest floor out of all players, you will be sitting at the top. The leaderboard adds a competitive element to the mode that usual solo grinding does not have. If you are the type of player who likes being ranked, this is your chance to show off.
Infinite Tower Shop
One of the biggest reasons to grind the Infinite Tower is the Tower Shop on Tower Island. You can open the shop by interacting with the NPC. This is where you can spend your coins on some seriously valuable stuff.
You can also use Tower coins to upgrade your tower, which boosts your damage output. This upgrade matters a lot as you push into higher floors where base stats alone will not be enough to carry you.
Tips for Climbing the Infinite Tower
Getting far in the Infinite Tower is not just about having good gear. Make sure your character is fully upgraded before climbing up the tower. The debuffs on high floors hit hard, and you need all the stats you can get. You should also get familiar with the debuff types as you encounter them, since knowing what you are dealing with helps you adapt faster.
Most importantly, do not ignore the daily rewards. Even if you are not pushing for the leaderboard, clearing the tower every day adds up over the season.
The Sailor Piece Infinite Tower mode is one of the best things to come out of this update. It gives you a real reason to keep grinding and a solid shop with a new items and accessories to unlock. If you have not headed to Tower Island yet, grab your Tower Key and get started. For more codes, tips, and info about this game, you can always check our dedicated Sailor Piece wiki.
