What Is Domain Expansion in Sailor Piece?

Domain Expansion is a special endgame ability tied to Sukuna V2 and Gojo V2. It unlocks their strongest move and adds a major damage boost during fights. To access it, you must first unlock the characters and then craft a domain shard using rare boss materials. Both domains are unlocked inside a special building on Shinjuku Showdown Island, the main area introduced in the update.

How to Unlock Sukuna Domain Expansion

Sukuna’s Domain Expansion requires crafting a Shrine Domain Shard and equipping a specific trait.

Sukuna Domain Requirements

You need the following materials:

• 6 Cursed Talismans
• 2 Infinity Essence
• Mythical Malevolent Trait

These items mainly drop from the new Sukuna boss on Shinjuku Showdown Island. After collecting everything, follow these steps:

Steps to Unlock Sukuna Domain

1. Craft the Shrine Domain Shard using the required materials.
2. Equip the Mythical Malevolent Trait on Sukuna.
3. Enter the domain building on Shinjuku Showdown Island.
4. Interact with the unlock area inside to activate Sukuna’s Domain Expansion.

Once unlocked, Sukuna gains access to his F-move, which has strong range, fast cooldowns, and useful invincibility frames for boss farming.

How to Unlock Gojo Domain Expansion

Gojo’s domain uses a different shard and materials, but the process is similar.

Gojo Domain Requirements

To craft the Infinity Domain Shard, you need:

• 6 Energy Shards
• 2 Cursed Flesh
• Mythical Infinity Trait

These materials drop from the Gojo boss on Shinjuku Showdown Island.

Steps to Unlock Gojo Domain

1. Craft the Infinity Domain Shard.
2. Equip the Mythical Infinity Trait on Gojo.
3. Go inside the same domain building on Shinjuku Showdown Island.
4. Interact with the unlock spot to activate Gojo’s Domain Expansion.

After unlocking, Gojo gains his domain F-move, which focuses on burst damage and crowd control.

Best Farming Tips for Domain Materials

Since domain items come from bosses, efficient farming is important:

• Farm in groups to defeat bosses faster.
• Focus on one boss at a time to avoid splitting drops.
• Save extra materials for future upgrades or trading.
• Use high-damage characters to speed up boss runs.

Sukuna is often preferred for faster farming once unlocked because of his strong cooldowns and range.

Unlocking Domain Expansion in Sailor Piece is a late-game goal that requires boss grinding and rare materials, but the reward is worth the effort. Sukuna and Gojo both gain powerful abilities that make farming and combat much easier. By focusing on material farming and meeting the trait requirements, you can unlock both domains and fully experience the Shinjuku Showdown update.
