If you’re diving into the world of Rogue Piece, you’ve probably heard whispers about the coveted Demonite Fragment. This legendary material is the key to unlocking some of the most powerful content in the game, including the exclusive Half-Demon Race and the devastating Yami Katana. As someone who has spent countless hours farming these fragments and mastering the Anti-Magic Dungeon, I’m here to share everything you need to know about obtaining and using Demonite Fragments effectively.

Quick Overview: Demonite Fragment at a Glance

Aspect	Details
Rarity	Legendary Material
Primary Source	Asta, Half-Demon Form (Wave 10 Boss)
Drop Rate	20-30% chance

What is a Demonite Fragment?

The Demonite Fragment stands as one of Rogue Piece’s most valuable Legendary materials, serving as the gateway to exclusive content that cannot be obtained through normal gameplay means. This crystallized demonic essence pulses with dark energy and holds the key to transforming your character’s very nature or crafting devastating weapons that rival the game’s best equipment.

Unlike common materials that drop frequently from regular enemies, Demonite Fragments are deliberately scarce, ensuring that only dedicated players who master the challenging Anti-Magic Dungeon can access their power. The fragments shimmer with an otherworldly purple glow, making them instantly recognizable in your inventory and highly sought after in the trading community.

How to Get Demonite Fragment: The Complete Method

Step 1: Accessing the Anti-Magic Dungeon

Before you can even think about obtaining Demonite Fragments, you need to gain entry to the Anti-Magic Dungeon. This exclusive instance serves as the proving ground for Rogue Piece’s most elite players, and entry doesn’t come cheap.

Entry Requirements:

5,000 Gems: Save up your gems through daily rewards, quests, and trading
10 Dungeon Tickets: These can be obtained through:
- Chest drops (random chance)
- Trading with the Dungeon NPC
- Completing previous dungeon runs (1 ticket per completion)

Pro Tip: I recommend stocking up on Dungeon Tickets before attempting serious farming runs. Each dungeon completion rewards you with 1 ticket, so successful runs become self-sustaining over time.

Step 2: Navigating the Anti-Magic Dungeon

The Anti-Magic Dungeon consists of 10 waves of increasingly difficult enemies. Here’s what to expect:

Waves 1-4 & 6-9: Magical Users

These enemies serve as warm-ups for the main event
Focus on building your combo and conserving resources
Each wave completion grants small rewards and prepares you for the next challenge

Wave 5: Asta, Anti-Magic Form

Don’t confuse this with your target! This is a different version of Asta
Defeating him is necessary but doesn’t drop Demonite Fragments
Use this wave to practice your timing and resource management

Wave 10: Asta, Half-Demon Form (THE TARGET)

This is where the real challenge begins
35,000,000 HP makes this one of the tankiest bosses in Rogue Piece
Bring your best gear and prepare for an extended battle

Step 3: Defeating Asta, Half-Demon Form

The final boss encounter requires strategy, preparation, and persistence. Here’s everything you need to know:

Boss Statistics:

Health Points: 35,000,000 HP
Difficulty: Legendary Boss
Recommended Level: Maximum level with optimized gear
Battle Duration: 10-30 minutes depending on your damage output

Drop Rates Table:

Item	Drop Rate	Rarity	Description
Demonite Fragment	20-30%	Legendary	Primary target material
Asta’s Outfit	10%	Legendary	+1 DEF, +1 STR, +1 Power, +2 Sword
Anti-Magic Sword	1%	Mythical	Weapon unlock
Anti-Magic Grimoire	1%	Mythical	Skill unlock (need 5 total)

Battle Strategy:

Preparation: Ensure you have maximum health potions and damage buffs
Positioning: Stay mobile to avoid his devastating area attacks
Timing: Learn his attack patterns and time your dodges perfectly
Resource Management: Don’t waste your strongest moves on his regular attacks
Patience: This is a marathon, not a sprint. Consistent damage beats burst attempts

Demonite Fragment Uses: Making the Right Choice

Once you’ve obtained your precious Demonite Fragments, you face an important decision: how to use them? Each fragment is valuable, and choosing the wrong path could set you back significantly.

Option 1: Unlocking the Half-Demon Race

The Half-Demon Race represents one of Rogue Piece’s most unique transformations, offering both significant advantages and notable drawbacks.

How to Unlock:

Obtain at least 1 Demonite Fragment
Use the fragment directly from your inventory
Face a 30% chance of successful transformation
If successful, your race permanently changes to Half-Demon

Half-Demon Race Bonuses:

Buff	Effect
Sword Damage	+15-25% increased sword damage
Power Defense	Reduced damage taken from Power-based attacks
Visual Change	Half of your avatar transforms with demonic features

The Major Drawback:

30% Maximum HP Reduction: This is significant and affects your survivability

My Personal Assessment: After extensive testing with the Half-Demon Race, I’ve found it excels in specific builds but struggles in others. If you’re a sword-focused player who can manage the HP reduction, the offensive benefits can be game-changing. However, for players who rely on tank builds or face high-damage content regularly, the HP penalty might be too severe.

Option 2: Crafting Yami’s Katana

The Yami Katana represents the pinnacle of sword weapons in Rogue Piece, introduced in the Black Clover Update of February 2026. This devastating blade combines dark magic with supreme swordsmanship, making it a must-have for serious sword users.

Complete Crafting Requirements:

Material	Quantity	How to Obtain
Demonite Fragments	25x	Asta, Half-Demon Form (20-30% drop)
Gems	25,000	Daily rewards, quests, trading
Darkness Katana	1x	Yami, Lord of Destruction Boss (1.25% drop)
Darkness Grimoire	1x	Yami, Lord of Destruction Boss (0.5% drop)
Darkness Magician Title	1x	Yami, Lord of Destruction Boss (5.4% drop)

Yami Katana Stats and Abilities:

Base Damage: Among the highest in the game for swords
Special Ability: Dark magic infusion attacks
Scaling: Excellent scaling with Sword and Power stats
Unique Moveset: Exclusive sword skills not available to other weapons

The Investment Reality: To craft the Yami Katana, you’ll need a minimum of 26 Demonite Fragments (25 for crafting + 1 to summon Yami for the other materials). Given the 20-30% drop rate, you’re looking at approximately 80-130 successful Asta defeats on average. This represents a significant time investment, so plan accordingly.

Advanced Farming Strategies

Having personally farmed hundreds of Demonite Fragments, I’ve developed several strategies to maximize your efficiency:

Strategy 1: The Batch Run Method

Instead of running the Anti-Magic Dungeon once and waiting, I recommend preparing for 5-10 consecutive runs. This approach offers several advantages:

Resource Efficiency: Bulk preparation reduces downtime
Skill Improvement: Consecutive runs build muscle memory
Drop Streaks: Sometimes the RNG favors players who stay active

Strategy 2: Team Farming

While the Anti-Magic Dungeon can be completed solo, bringing a team dramatically increases your success rate:

Optimal Team Composition:

1 Tank: High HP and defense to draw aggro
2 DPS: Maximum damage output to burn through 35M HP quickly
1 Support: Healing and buff capabilities

Team Benefits:

Reduced individual resource consumption
Faster completion times
Shared knowledge of boss patterns
Backup if someone disconnects

Strategy 3: The Off-Peak Advantage

Server population affects dungeon performance. I’ve found that farming during off-peak hours (typically early morning or late night) results in:

Smoother gameplay with less lag
More consistent boss behavior
Better drop rates (anecdotal but widely reported)

Common Mistakes to Avoid

Through my farming journey, I’ve seen many players make costly mistakes. Learn from their errors:

Mistake 1: Wasting Fragments on Early Attempts

Don’t use your first few Demonite Fragments immediately for the Half-Demon Race. The 30% success rate means you’ll likely need multiple attempts. Instead, save up 5-10 fragments before attempting the transformation.

Mistake 2: Poor Resource Management

Many players enter the Anti-Magic Dungeon unprepared, wasting precious resources on early waves. Always bring:

Maximum health potions
Damage buffs appropriate for your build
Backup weapons in case of durability issues

Mistake 3: Ignoring Other Drops

While Demonite Fragments are your primary target, don’t ignore other valuable drops:

Asta’s Outfit provides excellent stat bonuses
Anti-Magic Grimoires are crucial for skill unlocks
These items have significant trade value

Trading and Economy

Demonite Fragments maintain high value in Rogue Piece’s trading economy. Current market values (as of March 2026):

Trading Values:

Individual Fragment: 8-12 Hogyoku equivalent
Bulk Trades (10+): Slightly better rates
Half-Demon Race Services: 3-5 fragments typically
Yami Katana Crafting Services: 30-35 fragments (includes profit margin)

Trading Safety Tips:

Always use middlemen for high-value trades
Verify trade partner reputation in community forums
Never trade first with unknown players
Screenshot all significant trades

Frequently Asked Questions

How long does it take to get a Demonite Fragment?

Based on my extensive farming experience, the average player needs 3-5 Anti-Magic Dungeon runs to obtain one fragment, assuming 20-30% drop rate. Each run takes approximately 15-25 minutes depending on your gear and team composition.

Is the Half-Demon Race worth it in 2026?

The Half-Demon Race remains viable in 2026, particularly for sword-focused builds. However, with recent balance changes, I recommend considering your playstyle carefully. If you primarily use swords and can manage the 30% HP reduction, it’s absolutely worth it. For tank builds or players who struggle with survival, consider other options.

Can you buy Demonite Fragments?

Yes, but be cautious. While legitimate trading exists, scams are common. I recommend only trading with reputable community members or using official trading channels. Never buy fragments from suspicious sources offering “deals.”

What’s the fastest way to farm Demonite Fragments?

The fastest method involves:

Optimal team composition (Tank + 2 DPS + Support)
Preparing resources for 5+ consecutive runs
Learning Asta’s attack patterns perfectly
Using off-peak hours for better server performance

How many Demonite Fragments do I need for Yami Katana?

You need exactly 25 fragments for crafting, plus 1 additional fragment to summon Yami for the other materials. I recommend having at least 30 fragments before starting the Yami Katana questline to account for potential trade needs or crafting failures.

Can I get Demonite Fragments from other sources?

No, Asta, Half-Demon Form is the ONLY source of Demonite Fragments in Rogue Piece. Any other claims are false or refer to different items with similar names.

Final Thoughts

Demonite Fragments represent one of Rogue Piece’s most rewarding pursuits, offering access to exclusive content that can significantly enhance your gameplay experience. Whether you choose the path of the Half-Demon Race or the power of Yami’s Katana, the journey to obtain these fragments will test your skills, patience, and dedication.

Remember that farming Demonite Fragments is a marathon, not a sprint. Take breaks when frustrated, learn from each run, and don’t be afraid to experiment with different strategies. The community aspect of Rogue Piece is strong, so don’t hesitate to seek advice from experienced players or join farming groups.

As the game continues to evolve with new updates and content, Demonite Fragments will likely maintain their importance and value. By mastering the farming techniques and strategies outlined in this guide, you’ll be well-positioned to take advantage of future content updates and maintain your competitive edge in Rogue Piece.
