The Yamato sword is one of the most sought-after weapons in Sailor Piece on Roblox. Inspired by Vergil's iconic blade from the Devil May Cry series, it specializes in rapid slashes that produce dark blue slash effects on every ability. Despite its plain appearance, the sword's speed and damage output make it a top-tier option for melting bosses and dealing heavy burst damage in combat.
Quick answer: Talk to the Yamato NPC on Judgement Island after collecting the Blade Sovereign Title, Swordblessed Race, 1 Azure Heart, 3 Silent Storm, 7 Yamato Essence, 14 Frozen Will, and 30,000 Gems.
Yamato NPC location on Judgement Island
The sword is handed out by a specific NPC on Judgement Island. The fastest way to reach the island is through the teleport crystal, which warps you there directly. Once you arrive, head to the left side of the island and look for a layered, hill-shaped structure. Climb to the top, and you will find the Yamato NPC — a white-haired character wearing a blue coat and carrying a sword. Interact with this NPC to begin the exchange, provided you have every required item in your inventory.
Full list of required materials
| Item | Quantity | How to Obtain |
|---|---|---|
| Blade Sovereign Title | 1 | Yamato boss drop (1% chance) |
| Swordblessed Race | 1 | Random roll from Race Rerolls in your inventory |
| Azure Heart | 1 | Yamato boss drop (0.5% chance) |
| Silent Storm | 3 | Yamato boss drop (1.15% chance) |
| Yamato Essence | 7 | Yamato boss drop (2.5% chance) |
| Frozen Will | 14 | Yamato boss drop (4.25% chance) |
| Gems | 30,000 | Quests and treasure chests from enemies |
Four of the seven requirements — Azure Heart, Silent Storm, Yamato Essence, and Frozen Will — drop exclusively from the Yamato boss. The Blade Sovereign Title also comes from the same enemy, so the bulk of your time will be spent farming that single boss repeatedly.
Yamato boss stats and spawn timer
The Yamato boss spawns at the center of Judgement Island roughly every five to six minutes, making it one of the more farmable bosses in the game. It has approximately 850,000,000 HP and no displayed level, similar to the bosses found on Shibuya Station. Players with maxed-out Devil Fruit stats, high Haki levels, and strong meta fruits should be able to take it down without too much trouble. Expect the full grind to take anywhere from 10 to 15 hours of repeated kills, depending on your luck stat.
Yamato boss drop rates
| Drop | Chance |
|---|---|
| Trait Reroll | 100% |
| Race Reroll | 100% |
| Boss Ticket | 70% |
| Void Reaver Artifact | 65% |
| Dungeon Key | 60% |
| Frozen Will | 4.25% |
| Yamato Essence | 2.50% |
| Silent Storm | 1.15% |
| Blade Sovereign Title | 1% |
| Imperial Outfit | 0.90% |
| Azure Heart | 0.50% |
Azure Heart sits at just 0.5%, making it the rarest material you need. The Blade Sovereign Title at 1% is the second biggest bottleneck. Because you need 14 Frozen Will pieces at a 4.25% rate and 7 Yamato Essence at 2.5%, the total number of kills required adds up quickly, even for the "common" rare drops.
Improving rare drop chances with Luck
Boosting your Luck stat is the single most effective way to shorten the grind. Equip artifacts that increase Luck before you start farming the boss. The developers also occasionally run limited-time events that apply temporary Luck boosts server-wide, so keep an eye on the official Sailor Piece Discord for announcements about those windows.
Swordblessed Race and Blade Sovereign Title bonuses
Both of these requirements double as powerful permanent upgrades once equipped. The Swordblessed Race provides 3% Lifesteal, 80% Max HP, 10% Damage Reduction, 20% Sword Damage, and 75% Damage. The Blade Sovereign Title grants a flat 65% Damage boost. Pairing these two together with the Yamato sword significantly amplifies your overall damage output, making the lengthy farm worthwhile beyond just unlocking the weapon itself.
Detailed summary
Step 1: Use the teleport crystal to travel to Judgement Island. Head left and climb the multi-layered hill to locate the Yamato NPC at the top.
Step 2: Begin farming the Yamato boss at the center of the island. It respawns roughly every five minutes. Collect Azure Heart, Silent Storm, Yamato Essence, Frozen Will, and the Blade Sovereign Title from repeated kills.
Step 3: While waiting for the boss to respawn, use Race Rerolls from your inventory to spin for the Swordblessed Race. This is entirely RNG-based and may require many attempts.
Step 4: Accumulate at least 30,000 Gems through quests and treasure chests if you haven't already.
Step 5: Once every item is in your inventory, return to the Yamato NPC and complete the exchange. The sword will be added to your loadout immediately.
The Yamato sword rewards patience. Between the sub-1% drop rates on Azure Heart and the Blade Sovereign Title, plus the randomness of rolling the Swordblessed Race, most players should budget a full day of farming. Maxing your Luck stat before you start and equipping every artifact that boosts it will save you meaningful time over the course of dozens — or hundreds — of boss kills.
