When you start obtaining the Goku spec in Sailor Piece, it will look like you don’t need to fight the boss for it. Well, that is, unless the final quest comes around, where you must defeat the boss 50 times. And the gateway to the Goku boss is the Spirit Keys, a legendary type of item. So, don’t wander around and follow our guide to learn the ways to farm Spirit Keys in Sailor Piece fast.
Sailor Piece Spirit Key Farming Location
You can only obtain Spirit Keys by defeating the ‘Spirit Fighter’ NPCs on the Sailor Piece Sea 2 Blue Planet island. The official Sailor Piece patch notes suggest the Raid Keys are obtainable through melee fighting styles only. Luckily, there are no such limitations for Spirit Keys or Spirit Stones.
After you unlock Sea 2 in Sailor Piece, teleport to the Blue Planet. There, you will find a road leading to the left side of the map. Take it, and you will end up in a corner with five Spirit Fighter NPCs.
If you want to farm quickly, then we suggest you equip the top luck items. We used the Cosmic Being C skill to efficiently farm the NPC. We suggest going for the Sailor Piece best luck build to get more Spirit Keys fast.
Where to Use Spirit Keys in Sailor Piece
The Spirit Keys are only used to summon the Goku, aka Spirit Warrior boss in Sailor Piece. To find it, head back to the portal. Now, instead of taking the left route, go to the right one. Before a massive capsule, you will notice the NPC with the name Spirit Warrior Summoner.
Talk to the NPC, and a menu will open up. Here is the number of keys you will need to summon different difficulty levels of Spirit Warrior:
- Normal: 1 Spirit Key
- Medium: 2 Spirit Key
- Hard: 3 Spirit Key
- Extreme: 4 Spirit Key
You can farm enough of them and click the auto-spawn option. This will let you farm the Spirit Warrior boss quickly. Once you complete five quests and defeat 50 Goku bosses after that, the Spirit Warrior melee in Sailor Piece will be yours.
