Devil Hunter, also known as Chainsaw Man: Devil’s Heart on Roblox, has rapidly become one of the most immersive action-RPG survival experiences in the game platform. Whether you’re a newcomer or a seasoned player, one of the most intriguing and powerful transformations you can pursue is becoming a Fiend – a form that blends human resilience with otherworldly devil traits.
In this guide, we’ll walk you through everything you need to know about fiends – from what they are and how to unlock them, to progression tips and strategic advantages. Let’s dive in.
What Is a Fiend?
In Chainsaw Man: Devil’s Heart, a Fiend is a playable transformation that represents a devil possessing a human body. Unlike normal humans, fiends operate with a unique mechanic tied to devil contracts and their corresponding essence.
Fiends are considered a rare and powerful alternative to other character types. You can obtain a fiend by acquiring three contracts from the same devil type – a mechanic that requires dedication and strategy. Once transformed, fiends have all debuffs removed and gain a special transformation ability that enhances movement and combat prowess (activated by pressing T) at the cost of blood energy. They also gain the ability to consume dead bodies, similar to hybrids, restoring health and providing gameplay benefits.
There are multiple fiend types in the game so far, including Violence Fiend, Blood Fiend, and Shark Fiend – each with its own abilities, combat style, and playstyle focus.
Step-by-Step: How to Become a Fiend
Transforming into a fiend isn’t automatic – it requires preparation and specific steps. Here’s a clear breakdown of how to do it:
1. Reach Level 50
The first requirement is reaching level 50 in the game. You’ll gain experience (XP) by completing missions, hunting devils, and participating in world events. Leveling past 50 unlocks the ability to begin fiend transformation quests.
2. Obtain Three Contracts From the Same Devil
To qualify for fiend transformation, you must collect three contracts from the same devil type. Contracts are rewards tied to defeating certain devils and completing specific devil-related quests. They represent your character’s association with a devil’s power.
Earn these contracts via mission rewards, devil door interactions, and world event participation. Once you have three contracts from the same source – for example, three Blood Devil contracts – you’re eligible to pursue the next step.
3. Find the Fiend-Trigger NPC
Once you’re ready, locate the fiend transformation NPC. In many versions of the game, this NPC is an injured man underground, near a manhole around the center of the map. Interact with him to start the fiend summoning process.
4. Pay 10,000 Yen
To complete the fiend transformation, you must pay 10,000 Yen – the in-game currency. Once paid, the NPC will summon the devil associated with your contracts, consume you, and transform your character into a fiend.
After transformation, your fiend gains unique combat abilities, special stats, and access to transformations activated with the T key. In this form, you become more formidable on the battlefield with powers that reflect your devil’s nature.
Types of Fiends and Their Abilities
One of the exciting parts of becoming a fiend is gaining access to a fiend-specific movelist and abilities. While the game continues to evolve, here’s what’s known about some prominent fiend types:
Violence Fiend
The Violence Fiend is characterized by aggressive melee combat and crowd control. When transformed:
- You gain a plague mask aesthetic.
- Transformation grants electricity-infused attacks.
- Movesets include Grab Slam, Axe Kick, and Brutal Barrage, each with enhanced effects while in fiend form.
This type excels at close-range pressure and burst damage.
Blood Fiend
The Blood Fiend specializes in forming weapons made from blood, allowing for dynamic weapon generation and combo play:
- Skills include Blood Spear, Blood Scythe, and Blood Hammer.
- These abilities use blood energy instead of stamina and are excellent for versatile combat engagement.
Both fiend types and future fiends possess unique playstyles, making the transformation worth pursuing.
Fiend Progression: Gaining Fear and Talents
Instead of weapon mastery like humans, fiends progress through a unique system often referred to as Fear and Talents:
- Fiends earn Fear XP mainly by consuming devil flesh and body parts dropped from defeated enemies. Eating higher-rarity devil flesh yields faster Fear progression.
- As your Fear increases, you unlock fiend abilities such as charge attacks or enhanced movement.
- Combining Fear with talents gained from specific materials (often found in raids or missions) builds a powerful fiend build that can rival other top players.
This progression makes fiends rewarding for players who enjoy gradual power growth through combat and exploration.
Gameplay Tips on the Path to Fiend
Becoming a fiend isn’t just about grinding contracts – it’s about understanding your role and optimizing progression. Here are some player-tested tips:
Pick the Right Starting Path
When you first enter Devil Hunter, you’ll choose between starting as a human or a fiend. While humans get bonuses like boosted health and more contracts, fiends receive boosted regeneration but less HP overall.
This initial choice influences how early you can farm contracts. Starting as a human might make it easier to acquire the three same contracts needed for fiend transformation before switching later.
Explore Mission Types
Missions like “Hold the Line” or “Cleanup Duty” offer excellent XP and materials for progression. The Black Market, found via your N phone menu, sells devil parts and materials needed for progression and crafting.
Master Movement and Combat
Devil Hunter’s combat isn’t static – wall running, dashing, parrying, and aerial strikes factor heavily into high-rank gameplay. Mastering movement keys improves survivability in tough missions and when gathering contracts.
Beyond Fiend: What Comes Next?
Once you become a fiend and master your early talents, the game continues to offer deep progression avenues:
- World Events: These large encounters unlock further progression and are required to move past certain ranks.
- Skill Trees: Open with
Mand invest in fiend trees to unlock advanced abilities. - Joining Factions: Some players join factions like the Accuser for unique quests and rewards.
Every step forward in Devil Hunter builds on your foundation – and having a fiend at your disposal gives you unique flexibility whether in PvE or PvP situations. Devil Hunter is a rewarding and complex journey that blends contract hunting, steady leveling, and smart progression choices; by reaching level 50, collecting three contracts from the same devil, visiting the fiend NPC and paying 10,000, yen and mastering fiend combat along with Fear progression, you place yourself on the path to one of the most powerful and engaging transformations in the game, and whether you choose a Violence, Blood, or Shark fiend, each form delivers a unique playstyle that is well worth mastering.
