A recent Sailor Piece update added several major progression features, including the Alter clan/race, a new Shanks-inspired sword, and important crafting materials like Dark Grails. Because many of these systems are tied together, new players often get confused about where to start or how to unlock everything required for the new gear.
This guide breaks down the main parts of the update so you understand how to obtain the Alter race, where to find the Shanks sword, and what Dark Grails are used for.
How to Get the Alter Race (Alter Clan)
The Alter race—sometimes referred to as the Alter clan—is one of the newest and most powerful clan types introduced in the update. Instead of unlocking it through quests or boss drops, the only way to obtain it is through Clan Rerolls.
Players need to open the Clan menu and repeatedly reroll their clan until Alter appears.
Because the system is RNG-based, you may need a large number of rerolls before getting it. Some players obtain it quickly, while others may spend hundreds or even thousands of rerolls before seeing it appear.
Alter Clan Buffs
Once obtained, the Alter clan provides several powerful bonuses, including:
- +35% overall damage
- +50% maximum HP
- +10% melee damage
- +12% luck
- A special passive where every fifth ability deals increased damage
These bonuses make Alter one of the strongest clans for both farming and boss fights.
Shanks Sword Location
Another major addition in the update is a Shanks-inspired sword, which players can obtain from the Boss Island area.
To find it, travel to:
Boss Island → Upper platform near the boss NPC area
Near this location you’ll find the NPC related to the new sword system. Players can interact with the NPC to view the weapon requirements and unlock the sword if they have the required materials.
When testing the weapon, players will notice it includes a simple but effective moveset with fast slashes and dash attacks, making it strong for clearing groups of enemies.
Saber Alter Weapon Requirements
The Shanks-themed sword is closely tied to another extremely powerful weapon in the update called Saber Alter.
To unlock Saber Alter, players must collect several rare materials and bring them to the crafting NPC on Boss Island.
The requirements include:
- Corrupt Tyrant title
- Corrupt Crown
- 3 Corruption Cores
- 8 Alter Essence
- 15 Morgan Remnants
- 25 Dark Grails
- 35,000 Gems
Because of these requirements, Saber Alter is considered one of the most expensive weapons to obtain in Sailor Piece.
What Dark Grails Are
Dark Grails are a high-tier crafting material used primarily to unlock powerful late-game weapons such as Saber Alter.
These items are usually obtained through:
- High-level bosses
- Endgame dungeons
- Special update events
Since the weapon requires 25 Dark Grails, farming them becomes one of the main challenges for players trying to unlock Saber Alter.
The drop rate can vary depending on the boss or dungeon, so repeated farming is often necessary.
How to Farm Dark Grails
Although the exact drop sources may change depending on the update version, most players currently obtain Dark Grails through boss fights in higher-level areas or special dungeon encounters.
The best strategy is usually:
- Farm high-level bosses repeatedly
- Join groups or servers where bosses spawn frequently
- Focus on events tied to the update
Because Dark Grails are rare, farming them efficiently usually requires strong gear and high-level stats.
Level Requirements for Some Content
Another thing players should keep in mind is that some quests and systems in the update require higher player levels.
For example, certain quests connected to advanced progression require levels around 8500 or higher, meaning newer players may need to grind before accessing all update features.
If you’re still below these levels, focusing on farming enemies and completing earlier quests will help unlock these systems faster.
The Sailor Piece update introduces several powerful new progression systems, including the Alter clan, the Shanks-inspired sword, and rare materials like Dark Grails.
While some of these upgrades rely heavily on luck or grinding, they offer some of the strongest bonuses currently available in the game.
For players aiming to unlock the Saber Alter weapon or optimize their builds, focusing on clan rerolls, boss farming, and collecting Dark Grails will be the key steps moving forward.
