What is Domain Expansion in Sailor Piece?
Domain Expansion represents the pinnacle of power in Sailor Piece’s JJK Update. These specialized endgame F-moves are exclusive to Sukuna V2 and Gojo V2 characters, offering massive damage multipliers and unique mechanics that can completely change how you approach boss fights and grinding sessions.
Unlike regular abilities that you might unlock through simple progression, Domain Expansion requires careful planning, resource gathering, and strategic trait selection. The game doesn’t hand you these powers easily – you’ll need to invest significant time and effort into crafting the necessary items and meeting specific requirements.
The payoff, however, is absolutely worth it. Once unlocked, Domain Expansion provides:
- Massive damage boosts that can melt through endgame bosses
- Unique mechanics like invincibility frames (Sukuna) or crowd control (Gojo)
- Faster farming capabilities for late-game progression
- Access to exclusive content and farming strategies
Prerequisites: Before You Start Grinding
Before you dive into the Domain Expansion grind, make sure you meet these essential requirements. Trust me, you don’t want to waste precious materials because you missed a basic prerequisite.
Character Requirements
- Must have Sukuna V2 or Gojo V2 – The base V1 versions cannot learn Domain Expansion
- Character Level 500+ – Most players find success at higher levels due to boss difficulty
- Access to Shinjuku Showdown Island – This is where all Domain Expansion content takes place
Trait Requirements
This is crucial – you cannot unlock Domain Expansion without the specific Mythical Trait equipped:
- Sukuna: Must have Mythical Malevolent Trait equipped
- Gojo: Must have Mythical Infinity Trait equipped
⚠️ Pro Tip: Don’t waste materials if you’re still rolling for traits! The crafting NPC won’t even let you proceed without the correct Mythical Trait active. Focus on getting your trait first, then worry about materials.
Location Access
All Domain Expansion crafting and unlocking happens at Shinjuku Showdown Island, the main area introduced in the JJK Update. You’ll need to progress through the game naturally to unlock access to this island.
How to Unlock Sukuna Domain Expansion: Malevolent Shrine
Sukuna’s Domain Expansion turns him into an absolute PvE monster, perfect for players who love grinding and boss farming. His ability offers superior sustainability and faster cooldowns, making him the preferred choice for most farming scenarios.
Sukuna Domain Requirements

- Massive AoE: Excellent area of effect that clears mobs instantly
- Sustained DPS: Better for long fights and consistent damage output
How to Unlock Gojo Domain Expansion: Unlimited Void
Gojo brings the raw power and burst damage that many players crave. If you love seeing massive damage numbers and prefer a more aggressive playstyle, Gojo’s Domain Expansion is your path to dominance.
Gojo Domain Requirements

Gojo excels in situations where immediate impact and crowd control are essential:

- PVP Viability: Better suited for player versus player scenarios
- Visual Impact: Satisfying damage numbers for players who love big hits
Efficient Material Farming Strategies
The grind for Domain Expansion materials can be brutal if you’re not optimized. Here’s my proven strategy for farming materials efficiently:
The “Sukuna First” Rule
If you have access to both characters, unlock Sukuna’s Domain first. His faster cooldowns and superior farming capabilities will make gathering materials for Gojo’s Domain much easier.
Boss Rotation Strategy
- Don’t camp one spawn – Rotate between the Sukuna and Gojo bosses on Shinjuku Island
- Track respawn times – Bosses typically respawn every 5-10 minutes
- Server hop strategically – Move between servers to maximize boss encounters
Group Farming Benefits
- Soloing takes too long – Join public servers or Discord groups
- Faster boss kills = more drops per hour – Coordinate with other players
- Share materials – Some groups pool resources for faster completion
Optimization Tips
- Use high-damage characters – Speed up boss runs significantly
- Save extra materials – Developers often add V3 mechanics requiring same materials
- Focus on one boss at a time – Avoid splitting drops between different bosses
- Time your farming – Play during off-peak hours for less competition
💡 Insider Tip: Keep farming even after unlocking your first Domain. The materials will likely be needed for future updates, and having a stockpile puts you ahead of the curve.

Frequently Asked Questions
Q: Can I unlock Domain Expansion with Sukuna V1 or Gojo V1?
No. Domain Expansion is exclusive to the V2 variants of Sukuna and Gojo. You must upgrade your unit before attempting to craft the shard.
Q: Where is the Domain crafting NPC located?
The NPC is located inside a specific building on Shinjuku Showdown Island. Look for the distinct structure near the center of the boss spawn area.
Q: Which Domain is better for farming?
For pure boss farming and grinding, Sukuna is better because of his lower cooldowns and invincibility frames. Gojo is better if you need immediate burst damage or crowd control.
Q: Do I lose the Domain if I switch my Trait?
Yes, usually. Since the move requires the Mythical Trait to be active, rerolling your trait will likely disable or lock the ability until you roll the specific Mythical Trait again.
Q: Can I unlock both Domains?
Absolutely! You can unlock both Domains on the same account, but you’ll need to gather materials for each separately and have both V2 characters.
Q: How long does it typically take to unlock Domain Expansion?
For an average player grinding 2-3 hours daily, expect 1-2 weeks to unlock your first Domain. This varies based on luck with drops and farming efficiency.
Q: Are Domain Expansion materials tradeable?
Currently, most Domain Expansion materials are soulbound, meaning they cannot be traded between players. Always check the latest patch notes as this may change.
