The Abyssal Empress Sword is a top-tier weapon in Sailor Piece, sitting alongside the Atomic Sword and Shadow Monarch as one of the game's strongest blades. Inspired by Acheron's sword from Honkai: Star Rail, every attack releases purple and crimson auras with wide reach, making it excellent for crowd control in Boss Rush and the Infinite Tower. Unlike most high-tier weapons that require material gathering and crafting submissions, the Abyssal Empress follows a different acquisition path entirely — it's tied exclusively to Tower Island.
Quick answer: Buy the Abyssal Empress Sword from the Tower Shop NPC on Tower Island for 4,000 Tower Tokens. You can also obtain it as a rare drop inside the Infinite Tower or purchase it from the Robux shop for 1,399 Robux.
All Methods to Get the Abyssal Empress Sword
There are three distinct ways to add this weapon to your inventory. The Tower Token purchase is the most reliable free-to-play route, while the Infinite Tower drop is luck-dependent, and the Robux options skip the grind entirely.
| Method | Cost | Notes |
|---|---|---|
| Tower Shop (Tower Tokens) | 4,000 Tower Tokens | Infinite stock; most reliable free method |
| Infinite Tower drop | 1 Tower Key per run | Very low drop rate; higher floors improve odds |
| Robux Shop (standalone) | 1,399 Robux | Instant purchase, no grinding |
| Bundle: Atomic + Abyssal Empress | 2,449 Robux | Includes the Atomic Sword |
| Bundle: Strongest Shinobi + Abyssal Empress | 2,349 Robux | Includes the Strongest Shinobi style |
| Bundle: Atomic + Strongest Shinobi + Abyssal Empress | 3,349 Robux | Best value if you want all three |
Buying from the Tower Shop
Step 1: Open any Teleport Portal and travel to Tower Island. It appears as the last island on the teleport list.
Step 2: From the spawn point, walk straight toward the tower. The Tower Shop NPC stands on the right side near the entrance to the Infinite Tower portal.
Step 3: Interact with the NPC to open the shop. The Abyssal Empress Sword is listed at the top and has infinite stock, so you can purchase it whenever you have 4,000 Tower Tokens.
How to Earn Tower Tokens
Tower Tokens are an exclusive currency that only drops from clearing floors inside the Infinite Tower. No other activity in Sailor Piece awards them. To access the Infinite Tower, you need to meet two requirements: your character must be Level 8,500 or higher, and you must have at least one Tower Key in your inventory. Tower Keys drop at a high rate from NPC mobs, mini-bosses, and World Bosses throughout the game, so stock up before heading to Tower Island.
Step 1: Travel to Tower Island and speak to the Infinite Tower NPC (separate from the Tower Shop NPC, though they stand near each other).
Step 2: Click the Spawn button to open the Infinite Tower portal. One Tower Key is consumed each time you spawn the portal.
Step 3: Enter the portal and defeat waves of enemies and bosses on each floor. The higher you climb, the more Tower Tokens you earn per run.
Infinite Tower Debuff Scaling
The Infinite Tower gets progressively harder through a debuff system. Understanding how debuffs stack helps you plan how far you can realistically push in a single run.
| Floor Range | Debuff Behavior |
|---|---|
| Floors 1–49 | One random debuff every 5 floors (health, dodge, or damage reduction) |
| Floors 50–99 | Two random debuffs every 5 floors |
| Floor 100+ | Three random debuffs every 5 floors |
Early debuffs might reduce your health pool or dodge chance. By floor 50, the stacking becomes punishing enough that undergeared characters will struggle to survive. Reaching higher floors is the key to earning tokens efficiently, so pushing your build to its limits before entering matters more than running the tower repeatedly at low floors.
Farming Tower Tokens Faster
Collecting 4,000 Tower Tokens takes significant time, but a few strategies cut the grind down considerably.
Max out your Haki levels first. Armament Haki and Conqueror Haki both provide major damage increases. Higher damage means faster floor clears, which means more tokens per hour.
Equip your strongest gear before entering. Your best sword, devil fruit, accessories, artifacts, and runes should all be equipped. Stat points invested in Defense and health boosts from Titles, Clans, and Races improve survivability on higher floors where debuffs stack.
Form a team instead of running solo. Group runs let you push deeper into the tower in a single attempt, earning far more tokens while consuming only one Tower Key per player.
Use AFK farming when available. Toggle on Auto Skill and Auto Haki in the settings to let your character fight automatically. This works best when your gear is strong enough to handle floors without manual input.
Abyssal Empress Sword Moveset and Damage
The Abyssal Empress features six attacks, each with distinct animations involving purple and red visual effects. The damage numbers below reflect a fully buffed build (+20% sword damage, +280% damage, and ×2.3 damage multiplier). Your raw output will be lower without these buffs, but the relative power of each move stays the same.
| Key | Move Description | Damage (Buffed) |
|---|---|---|
| M1 | Standard sword slashes with purple and red effects | 320,000,000 |
| Z | Three rapid slashes with a short cooldown | 446,000,000 |
| X | Forward dash slash into a void effect and blast | 918,000,000 |
| C | Two slashes followed by fast red-purple strikes; large AoE | 1,700,000,000 |
| V | Cutscene attack with charged slashes and void effects across the arena | 4,200,000,000 |
| F | Domain cutscene attack with continuous slashes and scattered flower petals | 8,800,000,000 |
The V skill is particularly effective for clearing waves in the Infinite Tower and Boss Rush, since it hits a wide area with multiple slashes. The F skill deals the highest single-move damage in the sword's kit and creates a domain-style effect that locks down groups of enemies.
Other Tower Shop Rewards Worth Knowing
While farming tokens for the sword, you may also want to pick up the Abyssal Outfit (4,000 Tower Tokens), which is one of the strongest accessories in the game. The Void Empress Title cannot be purchased — it only drops as a rare reward from clearing Infinite Tower floors — but it provides a 77.5% damage buff when equipped, making it one of the most impactful titles available.
If you're already investing time in the Infinite Tower, keeping an eye out for these drops alongside the sword itself makes each run more worthwhile. The Abyssal Empress Sword has infinite stock in the Tower Shop, so there's no rush — farm at your own pace and buy it whenever you hit 4,000 tokens.
