How to Get Atomic Sword in Sailor Piece

The Atomic Sword is one of the high-tier weapons in Sailor Piece, known for its powerful burst damage, advanced combo potential, and strong late-game scaling. This weapon is not beginner-friendly to obtain—it requires grinding, boss fights, and collecting rare materials.

Atomic Sword Overview

The Atomic Sword is a late-game weapon designed for players who have already progressed into advanced islands and boss content. It focuses on fast, precise attacks and high DPS output.

• High burst damage and combo chains
• Special “F Move” unlock through mastery
• Boss-based progression system
• Scaling damage with upgrades and quests

Similar to other top-tier weapons in Sailor Piece, its full potential is only unlocked after completing additional mastery quests and repeated boss farming.

Material Preparation

Before obtaining the Atomic Sword, you need to prepare the following core materials in advance.

• Title (Must be equipped) - Eminence Incarnate
• Required Weapon (Must already own) - Shadow Sword
• Core Materials
  Atomic Omen ×1
  Eminence Essence ×3
  Shadow Remnant ×9
• Basic Materials
  Magic Shard ×16
  Abyss Sigil ×80
• 45,000 Gems

How to Get Atomic Sword

Step 1: Acquire the Prerequisite Weapon

To obtain the Atomic Sword, you must first possess a Shadow Sword; this serves as the foundation for the Atomic Sword. So, how do you unlock the Shadow Sword?
You first need to gather the necessary materials: 10,000,000 Money, 15,000 Gems, 20 Umbral Capsules, 1 Atomic Core, 4 Shadow Essences, and 8 Void Seeds. Next, travel to Dungeon Island, locate the NPC "Shadow Trainer," and complete the quest to defeat the "Shadow Warrior." However, the Shadow Sword drops randomly, so you will need to spend some time farming for it. It is recommended that you use a high-damage weapon or form a team to speed up the farming process.

Step 2: Gather All the Materials Mentioned Above

Among the required items, the Abyss Sigil is a material that demands patience to farm; it is relatively difficult to collect. It is required in large quantities, and there is no direct alternative method to obtain it—it can only be acquired by defeating enemies. It is recommended that you travel to Lawless Island and Ninja Island to farm by defeating the "Arena Fighter" and "Ninja" enemies.

Tips of Quick Farming

• Equip a Luck title (such as Lucky) to increase the item drop rate.
• Use weapons with a wide area of effect and high damage output to clear enemies quickly and save time.
• Choose a server with fewer players to avoid having your enemies stolen by others.

The acquisition methods for the remaining materials are listed in the table below.

Step 3: Travel to Lawless Island to Exchange

Use a portal to travel to Lawless Island. On the right side of the island, you will find the Atomic Seller. Speak with the NPC—ensuring that your inventory contains all of the required items—then click to perform the exchange. You will then successfully acquire the advanced weapon: Atomic Sword.

Step 4: Unlock the "F Move" (Optional)

If you wish to further enhance the damage output of your Atomic Sword, you can unlock an additional skill by completing the Mastery Quest. This will make your Atomic Sword even more powerful.

Quick Way to Get

Upon completing the steps outlined above, you will successfully acquire this top-tier piece of equipment. However, gathering the necessary materials is a lengthy process requiring a significant investment of both time and effort. If you lack the time—or if the item drop rates are simply too low, making it difficult to finally complete your collection—you can instead visit the Sailor Piece Shop. There, you can purchase the Atomic Sword directly, offering the quickest and easiest method to obtain it.
