The Universal NPCs: Found on Every Major Island

Before diving into specific islands, you need to master these two essential NPCs that appear on virtually every major island in Nexis Piece.

Teleporter NPC

Function: Instant fast travel between unlocked islands Location: Usually found at docks or main spawn areas Requirements: Must have previously visited the destination island or meet level requirements

Pro Tip: Always interact with the Teleporter NPC immediately upon discovering a new island. This unlocks it for future fast travel, saving you massive amounts of time during your grinding sessions.

Set Spawn NPC

Function: Updates your respawn location to the current island Location: Near spawn points or main areas Requirements: None (available to all players)

Critical Warning: Never ignore this NPC! I learned this the hard way after dying to a random mob on Boss Island and respawning all the way back on Starter Island. Set your spawn immediately upon arriving at any new grinding location.

Starter Island: Your Foundation for Success

Starter Island is where your journey begins, and despite its name, you’ll find yourself returning here frequently for essential quests and upgrades.

ItemQuest NPC

Quest Objective: Defeat 350 Bendy enemies Rewards:

Lord Kuromi Accessory (cosmetic but highly sought after)
6,000 Yen
4 Gems
1 EXP

Strategy: This quest requires significant grinding but provides a valuable accessory that boosts your power early on. Complete this before moving to advanced islands.

Katana Seller

Sells: Basic Katana Requirements:

5 Iron
2,500 Yen

Analysis: This is your first major weapon upgrade from the starter sword. While not the most powerful, it’s essential for early progression.

Dual Katana Seller

Sells: Dual Katana (superior to single Katana) Requirements:

15 Iron
10,000 Yen

Why It’s Worth It: The Dual Katana offers significantly faster attack speed and better hitboxes, making mob farming much more efficient. This is your first priority weapon upgrade.

Try It NPC

Sells: Mihawk’s Hat Requirements: Starter Sword, Iron Fist, Basic Cape Status: ❌ Currently unavailable in-game

Note: This NPC is listed in the game files but not yet implemented. Check future updates for availability.

Sandora Island: Mid-Game Weapon Haven

Once you’ve mastered Starter Island, Sandora Island offers your next weapon progression step.

Quake Spear Seller

Sells: Quake Spear Requirements:

10 Iron
5,000 Yen
12 Gems

Why Choose Quake Spear: If you’re tired of sword-based combat and want more range or AoE (Area of Effect) potential, the Quake Spear is your best option. It’s particularly effective against grouped enemies.

Center City: Endgame Power Central

Welcome to the big leagues! Center City is where you’ll find the most powerful (and expensive) abilities in Nexis Piece. The grind requirements here are steep, but the rewards are game-changing.

Cid Seller

Sells: Cid fighting style/ability Requirements:

100 Slime
50 Cid Shards
1 Orb Atomic
2 Eye Kagenou
540,000 Yen
890 Gems

Breakdown: This represents hundreds of hours of farming, but Cid is considered one of the most powerful abilities in the current meta. Start collecting these materials early, even if you’re not ready to purchase yet.

Sukuna Seller

Sells: Sukuna fighting style/ability Requirements:

20 Cursed Fingers
Must complete ItemQuest_1 (see Boss Island section)
540,000 Yen
890 Gems

Why Sukuna is Worth It: As the King of Curses, Sukuna offers devastating power that can carry you through endgame content. The quest requirement makes this a true achievement unlock.

Boss Island: Where Legends Are Made?

Boss Island is unique because it houses the NPCs that control the most challenging content in Nexis Piece. This is where you’ll test your mettle against powerful bosses and unlock the game’s most coveted rewards.

ItemQuest_1 NPC

Special Requirement: Must be holding the Heart Vessel item to interact Quest Objective: Kill 20 Ryomen bosses Rewards:

6,000 Yen
2 Gems
1 EXP

Strategy Note: This quest is primarily a prerequisite for unlocking Sukuna. The rewards themselves aren’t impressive, but completion is mandatory for endgame progression.

Boss Spawner NPC

Function: Summons powerful bosses for farming and quest completion

Boss Name	Drops/Rewards	Souls Given	Strategy Notes
The Vessel	Boss Token	900 Souls	Entry-level boss, good for farming
Ryomen	Heart Vessel (required for Sukuna quest)	800 Souls	Camp this boss for quest progression
Dark Spirit	Cursed Spirit (currency for Sid unlock)	1,200 Souls	High soul yield, essential for endgame currency

Pro Farming Strategy: To unlock Sukuna efficiently, you’ll need to camp the Boss Spawner NPC. Focus on farming Ryomen for the Heart Vessel quest and Dark Spirit for souls. Consider forming a party for faster clears.

Jiujutsu Island: Farming Paradise

While not mentioned in the basic NPC guides, Jiujutsu Island is arguably the most important location for serious progression.

Why Jiujutsu Island is Essential:

Semi-AFK Friendly: Mob spawns are clustered for efficient grinding
Resource Trinity: Drops Boss Tickets, Cursed Spirits, and Gems simultaneously
Optimal Level Range: Perfect for players level 75-200
Quest Rewards: Final quests here provide the best resource-to-time ratio

Farming Routine: Once you have decent gear (Bicento or better), make Jiujutsu Island your permanent farming location. Build a routine of completing the final quest repeatedly to stockpile endgame currencies.

Advanced NPC Knowledge: Hidden Gems and Secrets

Beyond the basic NPCs, there are several important locations and mechanics that many players miss:

Middle Island

Key NPC: Sukuna NPC (for final ability activation) Purpose: After completing the Sukuna questline, you must visit the Sukuna NPC on Middle Island to officially unlock and activate the ability.

City Island

Key NPC: Sid Seller Purpose: After farming Cursed Spirits from Jiujutsu Island and defeating the Sid Boss, visit City Island to purchase/unlock the Sid ability.

Daily Reset NPCs

Some NPCs have limited stock or reset their offerings daily. Make a habit of checking:

Weapon sellers for rare stock
Quest NPCs for new daily missions
Boss Spawner for special event bosses

Complete Character Unlock Guide

Based on our research, here’s the step-by-step process for unlocking the game’s most powerful characters:

How to Unlock Sukuna (Complete Guide)

Start Questline: Use Heart Vessel to trigger ItemQuest_1
Farm Ryomen: Kill 20 Ryomen bosses using Boss Spawner
Collect Cursed Fingers: Farm 20 Cursed Fingers (rare drops)
Gather Currency: Accumulate 540,000 Yen and 890 Gems

Travel to City Island: Locate the Sid Seller
Purchase Sid: Use the boss drop to unlock Sid ability

Weapon Progression Path: From Noob to Pro

Understanding which NPCs to visit for weapon upgrades is crucial for efficient progression:

Early Game (Levels 1-50)

Starter Sword → Katana (5 Iron, 2,500 Yen)
Katana → Dual Katana (15 Iron, 10,000 Yen)

Mid Game (Levels 50-100)

Dual Katana → Quake Spear (10 Iron, 5,000 Yen, 12 Gems)
Quake Spear → Bicento (best farming weapon)

End Game (Levels 100+)

Bicento → Cid (100 Slime, 50 Cid Shards, 1 Orb Atomic, 2 Eye Kagenou, 540,000 Yen, 890 Gems)
Cid → Sukuna (20 Cursed Fingers, complete ItemQuest_1, 540,000 Yen, 890 Gems)

Critical Warning: Avoid the Yoru blade in the current beta version. Despite its cool appearance, it’s underpowered compared to the Bicento and represents a common “noob trap” that wastes valuable resources.

Resource Management Strategy

Smart resource management separates successful players from those who grind endlessly. Here’s how to optimize your farming:

Iron Management

Early Game: Collect every Iron node you see
Priority: Save Iron for Dual Katana first, then Quake Spear
Tip: Iron becomes scarcer as you progress, so stockpile early

Gem Strategy

Source: Jiujutsu Island final quests
Usage: Save for endgame abilities (Cid/Sukuna)
Weekly Codes: Use “WeekCode” for 5,000 Gems weekly

Yen Farming

Best Location: Jiujutsu Island (semi-AFK friendly)
Daily Code: Use “DailyCode” for 10 Gems daily
Efficiency: Focus on one-shot builds for maximum Yen per hour

Common Mistakes to Avoid

After analyzing hundreds of player experiences, here are the most costly mistakes:

1. Ignoring Set Spawn NPCs

Never skip setting your spawn on new islands. The time lost from respawning on Starter Island is devastating to your progression.

2. Wasting Resources on Yoru Blade

The Yoru looks cool but is underpowered. Stick with Bicento until you can afford Cid or Sukuna.

3. Not Stockpiling Iron Early

Iron becomes increasingly rare. Always collect it, even if you don’t need it immediately.

4. Skipping Jiujutsu Island

Many players rush to endgame islands without realizing Jiujutsu Island offers the best resource farming rates for mid-game progression.

5. Ignoring Daily Codes

Free gems and rerolls accelerate your progression significantly. Check codes daily.

Pro Tips for Maximum Efficiency

1. Create a Farming Route

Plan your island visits to minimize travel time. Start with Starter Island → Sandora → Jiujutsu → Center City, setting spawns at each location.

2. Join the Official Discord

Developers post codes and update information on Discord. This gives you early access to new content and codes.

3. Party Up for Bosses

Form parties for boss farming. While you can solo bosses, parties clear faster and reduce the risk of death.

4. Time Your Purchases

Save major purchases (Cid/Sukuna) for when you have all requirements ready. Don’t waste resources on intermediate upgrades you’ll quickly replace.

5. Bookmark This Guide

Game updates can change NPC locations or requirements. Check back regularly for the most current information.
