Listen, I’ve spent countless hours grinding raids and farming contracts in Devil Hunter, and if you’re here, you probably want those powerful sea-based devil contracts everyone’s talking about. The Octopus Devil and Shark Contract are two of the most sought-after abilities in the game right now, and for good reason. They’re absolute beasts in both PvP and PvE content.
Here’s the thing though: getting these contracts isn’t as straightforward as picking up a Sea Cucumber or Leech Devil. Both require specific knowledge about raid mechanics, NPC locations, and some serious dedication. I’m going to walk you through everything you need to know to unlock both of these contracts as quickly as possible, so you can start dominating battles with underwater abilities and chance-based blocking that makes you nearly unstoppable.
| Feature | Octopus Devil | Shark Contract |
|---|---|---|
| Location | Katana Man Raid (3rd Floor Boss) | Floor Zero, Public Safety HQ |
| Drop Rate | 10% chance from Katana Man Raid | Interact with Shark Fiend NPC |
| Requirements | First Class Hunter Rank | Specific faction requirements |
| Difficulty | Hard (Raid Boss) | Medium (NPC interaction) |
| Best For | PvP Combat, Combo Extension | Defensive play, Chance blocking |
| Abilities | Grab attacks, Tentacle strikes | Underwater mobility, Bite attacks |
Before we dive into the specifics, let me explain how contracts work in Devil Hunter. A contract is a supernatural agreement between your human character and a devil. When you form a contract, you gain access to that devil’s unique abilities, but there’s always a price to pay—whether that’s a sacrifice of body parts, health, or specific stat debuffs.
The Octopus Devil and Shark Contract are both extremely powerful options, but they require different approaches to obtain. The Octopus Devil drops from one of the hardest raid bosses in the game, while the Shark Contract comes from an NPC interaction that many players miss entirely.
Critical Note: Only humans can form devil contracts. If you’re playing as a Fiend or Devil, you won’t be able to obtain these contracts. You’ll need to use a Wipe Token to restart as a human if you want to access them.

Before you even think about farming for the Octopus Devil, you need to meet these requirements:
Step 1: Locate the Katana Man Raid
The Katana Man Raid is one of the most popular farming spots in Devil Hunter. Here’s how to find it:
Step 2: Prepare for the Raid
This isn’t a casual stroll through the park. The Katana Man Raid is designed for late-game players, and you’ll need proper preparation:
Step 3: Clear the Three Floors
The Katana Man Raid consists of three floors, each with increasing difficulty:
First Floor: Regular enemies that are relatively easy to clear. Use this floor to warm up and practice your timing with dodges and parries.
Second Floor: Tougher enemies with more health and damage output. Stay mobile and don’t get greedy with your attacks.
Third Floor: This is where you’ll find the Ghost Devil boss (which can also drop the Ghost Contract at 10% chance) and progress toward the Katana Man boss who guards the Octopus Devil contract.
Step 4: Defeat the Boss
The Ghost Devil and Katana Man bosses use teleport-based combat, so here’s my tested strategy:
Step 5: Claim Your Reward (Maybe)
After defeating the boss, you have a 10% chance for the Octopus Devil contract to drop. If it doesn’t drop, don’t panic—this is normal. The good news is that the Katana Man Raid respawns regularly, so you can farm it multiple times.
Pro Tip: Recent updates may have changed the drop mechanics. Some players report guaranteed drops after defeating specific bosses, but the community consensus still suggests a 10% drop rate for Octopus Devil. Run the raid until you get it.
Once you obtain the Octopus Devil contract, you’ll gain access to powerful tentacle-based attacks:
The Octopus Devil is particularly strong when paired with contracts like Future Devil or Snake Devil, creating devastating combo chains that your opponents won’t see coming.

Unlike the Octopus Devil, the Shark Contract doesn’t come from a raid boss drop. Instead, you need to find and interact with the Shark Fiend NPC located in a specific area of the Public Safety Headquarters.
Step 1: Reach Floor Zero
Floor Zero is a special area within the Public Safety Headquarters that contains several important NPCs:
Step 2: Locate the Shark Fiend NPC
According to my research and player reports, the Shark Fiend resides in one of the corners of Floor Zero:
Step 3: Meet the Requirements
The exact requirements for the Shark Contract vary based on faction and progression:
Important: The information about Shark Contract requirements is less documented than other contracts. The game is still relatively new, and the community is still discovering all the exact requirements.
Step 4: Complete the Contract Agreement
Once you meet the requirements and find the Shark Fiend:
The Shark Contract provides unique underwater-themed abilities that make you incredibly mobile and dangerous:
The Shark Contract excels in aggressive, high-mobility playstyles. It’s perfect for ganking, ambushing enemies, and maintaining constant pressure in PvP scenarios.
Now that we’ve covered how to get both, let’s talk about which one you should prioritize:
Choose Octopus Devil if you:
Choose Shark Contract if you:
Here’s the thing most guides won’t tell you: you can equip up to three contracts simultaneously as a human. This means you don’t have to choose between Octopus and Shark—you can run both if you build correctly.
My recommended three-contract build for sea dominance:
This combination gives you defense, offense, and mobility all in one package. You’ll have answers for nearly every situation.
When farming the Katana Man Raid for Octopus Devil:
Every devil contract comes with debuffs. Here’s what to watch for:
Read the debuff carefully before accepting any contract. Some debuffs are manageable, others will destroy your build.
The Black Market is crucial for contract progression:
Pro Tip: Visit the Black Market frequently if you’re collecting multiple contracts. Body parts sell out fast, and you’ll need them for various devil offerings.
Here’s a crucial decision point: once you have three contracts from the same devil type, you can become a fiend by paying 10k yen to the injured fiend NPC. But should you?
My Recommendation: Stay human if you want to use multiple different contracts like Octopus and Shark together. Only become a fiend if you’re 100% committed to that specific devil type.
Here’s how I use Octopus Devil in actual combat:
This combo deals massive damage and gives opponents almost no counterplay window.
For Shark Contract ambushes:
The underground movement is especially powerful near chokepoints and objectives where enemies expect frontal assaults.
Know thy enemy—here’s how players will try to counter you:
Against Octopus Devil:
Against Shark Contract:
If Shark Contract requires Yakuza membership (still being confirmed by the community), here’s what you need to know:
WARNING: Joining Yakuza locks you out of Public Safety forever unless you use a Wipe Token (complete character reset). You also lose all current contracts when switching factions.
If you join Yakuza, you gain access to:
My Advice: Get Future Devil from Public Safety BEFORE joining Yakuza. Future Devil is relatively easy to obtain and provides crucial auto-block utility. Once you have it, then consider the Yakuza switch if you want Snake and potentially easier Octopus access.
I see this constantly—new players rushing into Katana Man Raid at level 15 with a wooden bat. Don’t do this. You’ll waste everyone’s time (if you’re in a group) or just die repeatedly (if solo).
Minimum Recommended Stats for Katana Man Raid:
Breaking a devil contract results in permanent death and complete stat reset. Yes, you read that right. If you fail to meet the terms of your contract, you lose everything and start from scratch.
Solution: Use Devil Erasers from the Black Market. They’re expensive, but they let you reset contracts safely without dying. Plan your contract loadout carefully before committing.
If you do decide to become a fiend, the Fear system determines your power level. Many players ignore it and wonder why their fiend feels weak.
How to Increase Fear:
Stats matter tremendously in Devil Hunter. Here’s what to prioritize:
For Humans (Contract Users):
Avoid: Don’t put points into Sanity or Resistance early game. These stats become relevant much later.
For Fiends:
Use your phone (press N) regularly to:
Before you start your contract grind, redeem these codes for free rerolls, yen, and other resources (updated February 2026):
To Redeem Codes:
Note: You must be at least First Class Hunter rank to redeem codes. Complete the tutorial first.
Current Active Codes (as of February 2026):
Pro Tip: Join the Roblox Devil Hunter group before launching the game. Some codes require group membership to work.
No, currently the only way to obtain the Octopus Devil contract is through the Katana Man Raid with a 10% drop chance. There are no alternative methods confirmed by the community.
This is still being debated in the community. Some sources suggest Shark Fiend is accessible to all factions through the Floor Zero NPC, while others indicate Yakuza requirements. Try accessing Floor Zero as Public Safety first before committing to a faction change.
The raid has a global cooldown ranging from 30 minutes to 1 hour depending on server conditions. You can run it as many times as you want, but you’ll need to wait between attempts. Use this downtime to farm yen, complete missions, or prepare for the next run.
No. Fiends cannot make new devil contracts. You must be human to sign contracts with devils. If you’re already a fiend and want these contracts, you’ll need to use a Wipe Token to restart as human.
The S-tier combination is: Future Devil + Octopus Devil + Shark Contract. This gives you defensive counters (Future), offensive grab combos (Octopus), and mobility/burst damage (Shark). You’ll have answers for every combat scenario.
Yes. Switching from Public Safety to Yakuza results in losing all your current contracts. This is why I strongly recommend getting Future Devil before making the switch—it’s the most important defensive contract in the game.
Realistically, expect:
Yes, but only with a Devil Eraser from the Black Market. These are expensive and refresh every 15 minutes with limited stock. Breaking a contract without an eraser results in permanent death.
Octopus Devil is generally considered stronger for competitive PvP due to its grab mechanics and combo extension. However, Shark Contract excels in ganking scenarios and mobile playstyles. Ideally, use both for maximum effectiveness.
Octopus Devil requires First Class Hunter rank to equip. Shark Contract requirements are less documented but likely require at least Junior Hunter or higher. Focus on ranking up through the Public Safety division system before attempting to farm either contract.
After extensive testing, here’s my honest assessment: Yes, both the Octopus Devil and Shark Contract are absolutely worth obtaining.
The Octopus Devil is one of the most versatile contracts in the game, offering both offensive and defensive capabilities that scale incredibly well into late-game content. The 10% drop rate from Katana Man Raid might seem intimidating, but the raid itself also drops valuable resources, yen, and has a chance for other rare contracts like Ghost Devil.
The Shark Contract provides mobility and burst damage that few other contracts can match. If it’s truly accessible without Yakuza requirements, it’s one of the easiest high-tier contracts to obtain once you know where to look.
Together, these two contracts create a sea-based playstyle that’s both fun and competitively viable. You’ll have the tools to chase down enemies, escape bad situations, and deliver devastating combo chains that opponents can’t counter easily.
My Recommendation for New Players:
For Advanced Players: If you’re min-maxing, consider the Yakuza route for Snake Devil access alongside these contracts. The Snake + Octopus + Future combination is one of the strongest in the current meta, providing grab combos, ragdoll potential, and defensive counters all in one build.
Remember to bookmark this guide and check back after major updates, as Devil Hunter is still actively being developed. Contract requirements, drop rates, and mechanics may change with new patches.
Now get out there and start hunting those sea devils. The waters of Devil Hunter are dangerous, but with Octopus and Shark contracts, you’ll be the apex predator everyone fears.
Good luck, and may the RNG gods bless your Katana Man Raid drops!
