Learn how to get the Shadow Sword in Sailor Piece, including all required materials, how to farm the Cid Dungeon, and where to find the NPC.

The Shadow Sword is a Mythical rarity sword in Sailor Piece, and one players target as they push into the mid-game. It's a well-balanced weapon with moves that cover a lot of area, including cutscene skills that deal heavy damage to both mobs and bosses.
Getting it isn't as simple as finding a drop. You need to farm the Cid Dungeon on Dungeon Island to collect specific materials, and you also need to have the Shadowborn race equipped before the Shadow Trainer NPC will even offer you the trade.
In this article, we'll walk you through everything you need to get the Shadow Sword in Sailor Piece, including the required materials, how to farm them, and where to find the NPC.

Shadow Sword Requirements

Before you start farming, you need to know exactly what the Shadow Trainer NPC requires before he'll offer you the trade.
You need the following items:
- Shadowborn Race (equipped, not just owned)
- 10,000,000 Money
- 15,000 Gems
- 8x Void Seeds
- 4x Shadow Essence
- 20x Umbral Capsules
- 1x Atomic Core
The Shadowborn race is a legendary-tier race obtained through race reroll items. Without this race equipped, the Shadow Trainer will not offer the sword even if all other materials are present. Make sure it's actively equipped when you approach the NPC, not just sitting in your Race Bag.

How to Farm the Materials

All the materials you need are found inside the Cid Dungeon. The Cid Dungeon portal is summoned by speaking to the Dungeon Master NPC on Dungeon Island, and dungeons are only unlocked for players who have collected all Dungeon Pieces in Sailor Piece. Summoning a portal costs a Dungeon Ticket, and up to four players can enter.
Once inside, the dungeon runs on a wave-based system. Common enemies drop Umbral Capsules, while the Cid Boss is your primary source for Shadow Essence and the Atomic Core. The Cid Boss spawns every 5 waves, specifically at Wave 5, Wave 10, and Wave 15.
You can choose between Easy, Medium, Hard, and Extreme difficulty. The higher the difficulty, the better the boss drop chances, though the Shadow boss will have significantly more health and damage on Extreme. Run the highest difficulty your build can handle comfortably to maximize drop efficiency.
