The Shadow Sword is a powerful weapon in Sailor Piece obtained by farming dungeon materials and trading them to a specific NPC on Dungeon Island. Players must collect rare drops from the Cid Dungeon and equip the Shadowborn race before they can claim the sword.
Quick answer: Farm the Cid Dungeon on Dungeon Island to collect 8 Void Seeds, 4 Shadow Essence, 20 Umbral Capsules, and 1 Atomic Core. Equip the Shadowborn race, then trade these materials plus 10 million Money and 15,000 Gems to the Shadow Trainer NPC on the roof of Dungeon Island to receive the Shadow Sword.
Shadow Sword Requirements
The Shadow Trainer NPC requires the following items before granting the Shadow Sword:
| Item | Quantity | Source |
|---|---|---|
| Void Seed | 8 | Cid Dungeon boss and wave drops |
| Shadow Essence | 4 | Cid Dungeon boss and wave drops |
| Umbral Capsule | 20 | Cid Dungeon boss and wave drops |
| Atomic Core | 1 | Cid Dungeon boss and wave drops |
| Money | 10,000,000 | Quest rewards and chest drops |
| Gems | 15,000 | Chest drops |
| Shadowborn Race | Equipped | Race rerolls |
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 materials are present.
Farming Cid Dungeon Materials
Step 1: Travel to Dungeon Island using the teleport menu. Locate the Dungeon Master NPC near the center of the island.
Step 2: Talk to the Dungeon Master and select the Cid Dungeon option. Enter the purple portal that spawns to begin the dungeon instance.
Step 3: Complete waves of enemies inside the Shadow Dungeon. The Cid boss spawns every five waves (Wave 5, Wave 10, Wave 15). Defeat the boss and all wave enemies to maximize drop chances.
Drop rates are not guaranteed. Most players need to run the dungeon multiple times to collect all required materials. Higher difficulty settings increase drop rates for rare items like Atomic Core and Shadow Essence, but also increase enemy health and damage.
Difficulty recommendations: Easy mode is suitable for initial runs and farming common materials like Umbral Capsules. Medium or Hard mode improves drop rates for Shadow Essence and Atomic Core without excessive difficulty. Extreme mode offers the highest drop rates but requires strong gear and stats to complete efficiently.
Players can purchase some materials from the Dungeon Shop on Dungeon Island using Dungeon Tokens earned by completing Cid Dungeon runs. This provides an alternative path if specific drops remain elusive after multiple attempts.
Obtaining Shadowborn Race
Use race reroll items from your inventory to randomize your current race. Shadowborn is a legendary-tier race with a low pull rate. Players should store other legendary or mythic races in the Race Bag storage system before continuing rerolls to avoid losing valuable alternatives.
The race reroll menu includes a skip list feature. Configure it to skip common and uncommon races to speed up the process. Do not skip legendary-tier races, as Shadowborn falls into this category.
Once Shadowborn appears, equip it immediately. The race must remain equipped when speaking to the Shadow Trainer, or the trade will not trigger.
Trading for the Shadow Sword
Step 1: Return to Dungeon Island after collecting all materials and equipping the Shadowborn race. Climb to the roof of the main building on the island.
Step 2: Locate the Shadow Trainer NPC on the rooftop. Interact with the NPC to open the trade menu.
Step 3: Confirm that all required items appear in the trade window: 8 Void Seeds, 4 Shadow Essence, 20 Umbral Capsules, 1 Atomic Core, 10 million Money, 15,000 Gems, and Shadowborn race equipped. Select the "Buy Shadow" button to complete the exchange.
The Shadow Sword will appear in your weapon inventory immediately after the trade. Equip it from the inventory menu to begin using its abilities.
Shadow Sword Abilities
The Shadow Sword features multiple combat abilities accessed through different key bindings:
| Key | Ability | Effect |
|---|---|---|
| Left Click | Basic Attack | Standard melee slash |
| Z | Triple Slash | Three consecutive slashes followed by a forward dash |
| X | Shadow Strike | Forward dash with a powerful slash |
| C | Shadow Barrage | Area-of-effect attack with high critical hit chance |
| V | Shadow Execution | Single-target high-damage attack with low cooldown |
The V ability deals approximately 28 million damage per hit against standard enemies and has a short cooldown, making it effective for boss farming. The C ability covers a wide area and works well for clearing enemy waves in dungeons.
Players can enable auto-skill settings in the game menu to automatically use specific abilities during AFK farming sessions. This feature helps maintain consistent damage output without manual input.
Common Issues and Solutions
Shadow Trainer does not offer the trade: Verify that the Shadowborn race is currently equipped, not just stored in the Race Bag. The NPC checks active race status when opening the trade menu.
Missing materials after dungeon runs: Check the full inventory, not just the quick-access slots. Dungeon drops often appear in the main inventory grid and may require scrolling to locate. Umbral Capsules and Void Seeds stack, so the counter may not update visibly if the stack already exists.
Insufficient Dungeon Tokens for shop purchases: Each Cid Dungeon completion awards tokens based on difficulty and performance. Higher difficulties and faster clear times yield more tokens per run. Tokens accumulate across all dungeon attempts and persist between sessions.
The Shadow Sword remains in the player's inventory permanently after acquisition. It does not require re-farming or maintenance materials to continue using.
