You don't need to hunt down the Goku boss itself
In the layered world of Sailor Piece, progress is rarely given freely — it must be earned through repetition and patience. The Goku quest, a six-part chain of escalating demands, asks players first to seek out Spirit Stones from Spirit Fighter NPCs on Blue Planet island in Sea 2, a task that mirrors the oldest of human trials: the gathering of rare things before a greater journey can begin. Three stones, consumed in sequence, open the door to the next challenge — the rolling of the Empyrean Bloodline — reminding us that in games as in life, each threshold crossed simply reveals the next.
- Players pursuing the Goku quest hit an early wall: Spirit Stones are required to advance, and they don't drop themselves.
- The grind is real — Spirit Fighter NPCs on Blue Planet island must be defeated repeatedly, with no shortcut or guaranteed drop rate.
- The good news is that no specific combat style is required, giving players full freedom to bring melee, swords, or fruit abilities to the fight.
- Collecting three stones is only half the task — each must be consumed through the inventory, triggering a quest prompt that confirms progression.
- Once all three are consumed, the quest pivots entirely: the next demand is rolling the Empyrean Bloodline, launching a fresh grind.
Working through the Goku quest in Sailor Piece means accepting that progress comes in stages — and the first stage has a clear price: Spirit Stones. These items don't come from the Goku boss itself, but from Spirit Fighter NPCs found on Blue Planet island in Sea 2. After teleporting to the island, players head left from the portal and push straight ahead, where the NPCs are clustered on the left side of the map.
The farming process is straightforward if not effortless. There are no combat restrictions — melee, swords, and quake fruit all work equally well — though only one group of NPCs is available to farm. Players have found success with varied ability combinations, suggesting the game rewards flexibility over any single optimal strategy.
Once the stones are in hand, using them requires nothing more than opening the inventory, selecting the Spirit Stone, and confirming the consume prompt that appears on screen. Three stones must be consumed in total to clear the quest's first phase — a simpler process than unlocking items like the Aizen sword, which demands additional proof of effort.
With the first phase complete, the quest shifts its focus entirely: players must now roll the Empyrean Bloodline, beginning a new chapter of the chain. The path to Blue Planet is clear, the method is open, and the next horizon is already visible.
If you're working through the Goku quest in Sailor Piece, you'll eventually hit a wall that requires Spirit Stones. The good news is that you don't need to hunt down the Goku boss itself to make progress. Instead, the game asks you to complete a six-part quest chain, and the first step is straightforward: collect and consume these mythical items.
Spirit Stones drop from Spirit Fighter NPCs, and you'll find them on Blue Planet island in Sea 2. It's a standard farming grind—the kind that requires patience and repetition, but nothing exotic. Once you teleport to the island, head left from the portal and move straight ahead. The NPCs are waiting on the left side of the map. There's no trick to it; you just need to defeat them repeatedly until the stones start dropping.
Unlike some other items in Sailor Piece—raid keys, for instance—Spirit Stones have no combat restrictions. You can bring whatever fighting style suits you. Melee works. Swords work. Even quake fruit will do the job, though you'll only find one batch of NPCs to work through. One player grinding for the quest used a combination of Cosmic Being and Ice Queen to farm the stones efficiently, which suggests you have real flexibility in your approach.
Once you've collected the stones, using them is simple. Open your inventory, find the Spirit Stone, and click it. A prompt will appear at the top of the screen asking you to consume the item for the Goku quest. That's the entire process. You don't need to prove your worth the way you do for other items like the Aizen sword; you just consume them directly.
You'll need three Spirit Stones to clear the first part of the quest and move forward. After you consume all three, the game will ask you to roll the Empyrean Bloodline, which introduces the next phase of the chain. That's where your attention shifts, and where a new farming grind begins. For now, though, the path is clear: get to Blue Planet, find the Spirit Fighters, and start grinding.
The Hearth Conversation Another angle on the story
Why does the game make you farm Spirit Stones instead of just dropping them from the Goku boss itself?
It's a design choice that spreads the quest across multiple steps and locations. The Goku boss is the final payoff, not the grinding point. The stones are the gate.
So you're saying the six-part quest is deliberately paced to keep you moving between different challenges?
Exactly. Each part introduces a new item or mechanic. Spirit Stones are just the first lock. After that comes the Empyrean Bloodline roll, and presumably more gates after that.
Is there any reason to use one combat style over another when farming these NPCs?
Not really. The game doesn't restrict you the way it does with raid keys. Use whatever you're comfortable with. Some players mix styles to keep it interesting.
What's the actual time investment here? How long does it take to get three stones?
That depends on drop rates and how efficient you are. The source doesn't specify exact numbers, but it's described as a patience-and-grinding situation. Could be thirty minutes, could be longer.
And once you have the stones, there's no puzzle or challenge to consuming them?
No. It's just inventory management. Click the stone, confirm the consumption, and you're done. The real work is the farming part.
