What Changed on March 25, 2026
The Infinity Tower update, which landed on March 25, 2026, reshaped Sailor Piece in two significant ways: it introduced a brand-new endless challenge mode and dropped two Mythical-rarity swords into the loot pool simultaneously. That combination — new high-end content paired with dedicated exclusive rewards — is precisely the kind of update that resets progression hierarchies and gives both veterans and newcomers a concrete goal to chase.
The Infinite Tower: How It Works
The headline feature is the Infinite Tower gamemode. Unlike standard boss encounters that end the moment a target is downed, the Tower runs indefinitely, floor by floor. Each floor you clear brings you face-to-face with stronger enemy variants and a fresh layer of debuffs designed to chip away at your character's effectiveness. There is no ceiling — the floors keep scaling up as long as you can survive.
Because the Tower's rewards are exclusive and cannot be obtained anywhere else in Sailor Piece, it immediately became the single most important repeatable activity for players looking to push their progression. If you are farming a race reroll before tackling the high-HP Sea 2 bosses like the Cosmic Being (499 billion HP, spawning every 15 minutes at Punch Island) or the Kraken (1.25 trillion HP, Sea 2), the Tower is now the logical checkpoint before you make that leap.
The floor-by-floor structure also means your build is tested in a fundamentally different way than traditional content. A boss encounter in Sailor Piece has a defined HP bar and a fixed attack pattern. The Tower layers cumulative debuffs on top of escalating enemy stats, which means raw damage output alone will not carry you. Survivability, damage reduction, and smart ability timing all matter more the higher you climb.
New Swords: Atomic and Abyssal Empress
Atomic
The Atomic is a Mythical rarity sword priced at 45,000 gems, making it the most gem-expensive sword added to Sailor Piece to date. Its design focus is high AoE burst damage and boss clearing, and the community widely considers it a direct upgrade to the Shadow sword — which itself costs 10,000,000 money and 15,000 gems and is described as a well-balanced mix of burst and sustained damage. Where Shadow hedges between both output types, Atomic leans decisively into burst, particularly effective against groups of enemies or multi-phase boss encounters where detonating large damage spikes on a cooldown determines the pace.
Here is how Atomic compares to the other gem-purchasable Mythical swords available before this update:
| Sword | Rarity | Gem Cost | Money Cost | Combat Focus |
|---|---|---|---|---|
| Shadow | Mythical | 15,000 | 10,000,000 | Balanced burst and sustained |
| Yamato | Mythical | 30,000 | — | High sustained damage |
| Moon Slayer | Mythical | 37,500 | — | Consistent, small-area AoE |
| Atomic | Mythical | 45,000 | — | AoE burst and boss clearing |
At 45,000 gems, Atomic sits at the top of the gem cost chart among swords. That price tag signals this is a deliberate late-game investment — you want solid progression through Sea 2 and a healthy gem reserve before committing.
Abyssal Empress
The Abyssal Empress is also a Mythical rarity sword, focused on high burst damage in a more targeted form than Atomic. Unlike Atomic, Abyssal Empress does not have a direct gem shop listing, which strongly suggests it is tied to the Infinite Tower's exclusive reward pool or drops from a specific high-level condition. Both swords share the standard six-key Mythical moveset layout — Click, Z, X, C, V, F — that the rest of the Sailor Piece Mythical sword roster uses.
Meta Impact: Who Benefits Most
The Infinity Tower update reshapes the current meta in three clear ways:
- 1It creates a meaningful gem sink. Atomic at 45,000 gems gives gem-rich players who already own Shadow a defined upgrade target. Before this update, the highest gem cost for a sword was Moon Slayer at 37,500 gems.
- 2It establishes a dedicated endgame loop. The Tower's exclusive rewards mean serious players now have a reason to return that is independent of boss spawn timers. This is structurally different from the existing content, which revolves heavily around waiting for world bosses or sea creatures to respawn.
- 3It rewards survivability as much as damage. Stacking debuffs over many Tower floors punish glass-cannon builds. Players relying on pure offense will hit a wall; those who invested in HP and damage reduction will climb further.
For sword users, the Leviathan race is arguably the best complement for Atomic inside the Tower: +65% Max HP, +60% Damage, +17% Sword Damage Multi, and +5% Lifesteal. That lifesteal becomes a meaningful sustain tool on long Tower runs where healing items may not be available. The Luckborn race (+90% Max HP, +15% Sword Damage Multi, +80% Damage) is a strong alternative when maximizing raw damage output is the goal.
For fruit users, Light Fruit (legendary) provides excellent movement via its V-move, useful for repositioning around Tower debuff zones, while Quake Fruit (epic) delivers massive AoE NPC damage that can accelerate clearing the Tower's earlier floors quickly.
How to Prepare Before You Climb
Going into the Infinite Tower underprepared wastes time and potential exclusive rewards. Here is a practical checklist:
- Clear Sea 1 boss content first. The Corrupted Knight (750 million HP, Boss Island, Sea 1) is a reliable benchmark. If you are struggling there, the Tower will be extremely punishing.
- Build your gem total deliberately. If Atomic is your target, do not spend gems on transitional swords you will quickly replace. Set 45,000 as the milestone and hold there.
- Pick a race that synergizes with your weapon. Leviathan for sword users, Oni (+65% Max HP, +20% Melee Damage Multi, +10% Damage Reduction) for melee users who want defensive upside inside the Tower.
- Redeem active codes before your run. Check the Sailor Piece codes page — free gems, XP boosts, or rerolls available at the time of your run can make a measurable difference on a difficult Tower floor.
- Understand debuff types before climbing. Tower debuffs accumulate floor by floor. Going in without knowing what debuff each tier applies means you will hit an invisible ceiling that preparation would have removed.
Frequently Asked Questions
How do I get Abyssal Empress?
Abyssal Empress is a Mythical burst-damage sword added in this update. It does not have a listed gem shop price, so it is most likely obtained through the Infinite Tower's exclusive reward pool or a specific drop condition tied to high-level Tower progress. Keep climbing floors to work toward it.
Is Atomic worth 45,000 gems?
If you are already running Shadow and looking for your next upgrade, yes. Atomic is the direct evolved form of Shadow with a clear shift toward AoE burst, which is powerful in the Infinite Tower and against multi-enemy boss phases. The price is steep but it marks the top of the gem-purchasable sword ladder.
Do Tower rewards reset daily?
The update does not specify a confirmed daily reset schedule for Tower rewards. Treat it as an ongoing farmable activity and watch the official patch notes for any changes to reward timing.
Which race is best for climbing the Tower?
Leviathan is the best pick for sword users due to its Sword Damage Multi and Lifesteal combination. Oni is the strongest defensive option for players struggling to survive higher floors. For builds focused purely on melee weapons, Oni also provides a 20% Melee Damage Multi bonus on top of its damage reduction.
