As you advance in Sailor Piece, weapon upgrades become increasingly important for maintaining strong damage output and clearing content efficiently. The Shadow Sword F Move is one of those upgrades that stands out, not just because of the ability itself, but due to the long-term advantage provided by its permanent damage boost.
Once you obtain the Shadow Sword and speak to the Shadow Master, all six quests unlock at once, allowing you to progress them together rather than individually.

1 – Dealing 1 billion total damage
This is the most time-intensive requirement, but it progresses naturally through regular gameplay. Every attack you land contributes, so the key is maintaining constant combat rather than focusing on burst damage alone. Farming in high-density enemy zones or repeatedly engaging bosses helps accelerate progress significantly. Over time, as you complete other objectives like NPC kills and dungeon runs, this requirement will steadily fill up without needing separate attention.
2 – Defeating 1,250 NPCs
This quest focuses on consistent enemy farming and works best when paired with your damage grind. Areas with fast respawn rates and tightly packed enemies are ideal, allowing you to chain kills efficiently. Instead of waiting for enemies to reappear, moving through farming routes keeps the pace steady. Since NPC fights are the backbone of most activities, you’ll likely complete this objective alongside the damage requirement without extra effort.
3 – Defeating 150 bosses
Boss farming is more about efficiency than difficulty. Rather than targeting high-level bosses that take longer to defeat, focusing on easier bosses with quick respawn times speeds up progress. Many players rely on Boss Island due to its accessibility and fast farming loops. While the number may seem high, consistent boss rotations and minimal downtime make this quest surprisingly manageable over time.
4 – Completing 10 CID dungeons (Easy mode)
Easy mode dungeons are the fastest to complete and serve as a foundation for your dungeon progress. These runs are typically straightforward, allowing you to focus on speed rather than survival. With strong area damage abilities, you can clear waves quickly and finish objectives in minimal time. Because of their low difficulty, this part of the questline is usually completed first and helps build momentum for the harder modes.
5 – Completing 10 CID dungeons (Medium mode)
Normal mode introduces a more balanced challenge, requiring better awareness and consistent performance. Enemies deal more damage and take longer to defeat, so your build and playstyle matter more here. While still manageable solo, some players prefer grouping to reduce completion time. As you progress through these runs, you’ll naturally improve your combat efficiency, which helps with the remaining objectives.
6 – Completing 10 CID dungeons (Hard mode)
Hard mode is the most demanding part of the questline and requires proper preparation. Enemies hit significantly harder, and mistakes can quickly lead to failure, making survivability just as important as damage output. Strong gear, optimized builds, and familiarity with dungeon mechanics are essential. Although slower than other objectives, this stage represents the final test before unlocking the Shadow Sword’s full potential.
Why the Shadow Sword F Move is a must-have upgrade
This unlock is a long-term investment in your character’s strength. Because every activity in Sailor Piece benefits from higher damage, this upgrade improves your efficiency across the board, reducing grind time and making tougher content more manageable.
| Reward Type | Description |
|---|---|
| Shadow Sword F Move | Unlocks a powerful new ability |
| Permanent Damage Boost | +30% increase to all damage output |
The reward makes the entire grind worthwhile. The Shadow Sword F Move enhances your combat toolkit, while the permanent +30% damage boost provides a massive advantage across all activities, from farming to boss fights and dungeon clears.
