The world of Rogue Piece has been transformed with the massive My Hero Academia update, introducing two game-changing powers that every player wants to get their hands on: Deku’s legendary One For All and Shigaraki’s terrifying Decay abilities. As someone who’s spent countless hours testing both powers and mastering their acquisition methods, I’m here to give you the most comprehensive guide available anywhere online.
In this ultimate guide, you’ll discover exactly how to obtain both powers, which one suits your playstyle better, and pro tips that most players miss. Whether you’re a seasoned veteran or just starting your journey, this guide will save you hours of grinding and frustration. Let’s dive into the complete breakdown of these incredible abilities!
Before we get into the detailed step-by-step processes, let me give you a quick comparison of both powers so you can decide which path to pursue first:
| Feature | Shigaraki (Decay) | One For All (Deku) |
|---|---|---|
| Acquisition Difficulty | Moderate (Boss-focused) | Hard (Extensive questline) |
| Time Investment | 2-4 hours with team | 6-10+ hours solo |
| Power Level (Early) | Excellent | Weak (base) → Strong (full) |
| Best For | Early-mid game progression | Late game dedicated players |
| Team Requirement | Recommended for boss | Optional but helpful |
| Resource Cost | Boss materials only | Quest completion + materials |
Shigaraki’s Decay powers represent the more straightforward path to incredible strength in Rogue Piece. I’ve found this to be the most efficient choice for players looking to make immediate progress, and here’s exactly how to obtain it.
To unlock Shigaraki’s devastating Decay abilities, you’ll need to collect three specific materials, all of which drop exclusively from the Shigaraki Boss:
The first challenge you’ll face is actually summoning the boss himself. Here’s the exact process:
Pro Tip: Before attempting to summon, make sure you have a team ready. The Shigaraki Boss is no joke, and going solo is essentially suicide unless you’re maxed out with end-game gear.
This is where the real challenge begins. The Shigaraki Boss comes packed with an intimidating 3 million HP, making him one of the toughest bosses in the current meta. Here’s my battle-tested strategy for taking him down:
Based on my experience, here’s the optimal team setup:
Personal Experience: I tried this boss solo three times before realizing it’s virtually impossible without a well-coordinated team. My fourth attempt with a proper group took us about 12 minutes to defeat him.
Once you’ve successfully defeated the Shigaraki Boss and collected all the required materials, here’s how to claim your reward:
Important Note: Make sure you have enough inventory space before initiating the exchange, as some players have reported issues when their inventory is full.
One For All is undoubtedly the more complex and time-consuming power to obtain, but for dedicated players who love the My Hero Academia series, it’s absolutely worth the effort. I’ve completed this questline multiple times, and I’m here to walk you through every step.
Your journey to mastering One For All begins with the symbol of peace himself. Here’s exactly what you need to do:
All Might will give you two introductory quests that serve as your initiation into the One For All power system. Based on my experience, these quests typically involve:
Quest 1: Basic Training
Quest 2: Power Awakening
Critical Warning: The base version of One For All you receive from completing All Might’s quests is extremely weak. I made the mistake of thinking this was the full power and wasted time trying to use it effectively. Don’t fall into this trap!
This is where the real journey begins. After completing All Might’s quests, you’ll need to seek out the Deku Quest NPC to unlock the true potential of One For All.
The Deku questline is significantly more extensive and challenging than All Might’s introductory quests. Here’s what you can expect:
Quest 3: Full Cowl Training
Quest 4: Power Control
Quest 5: Final Awakening
Personal Experience: The full One For All questline took me approximately 8 hours to complete, spread across two days. The satisfaction of finally unlocking the full power was incredible, but I won’t lie—it requires serious dedication.
Here’s how your One For All power evolves throughout the questline:
| Stage | Power Level | Abilities Available | Recommended Use |
|---|---|---|---|
| Base (All Might) | Very Weak | Basic punches, minimal speed boost | Training only |
| Full Cowl (Deku Quest 3) | Moderate | Enhanced speed, stronger attacks | Early combat |
| Power Control (Deku Quest 4) | Strong | Area attacks, defensive moves | Mid-game content |
| Final Awakening (Complete) | Very Strong | Full power suite, ultimate abilities | End-game content |
After extensive testing of both powers, I have strong recommendations for which path players should pursue first. This decision can significantly impact your progression speed and overall enjoyment of the game.

What I Wish I Knew Earlier:
Based on my research and community interactions, here are the most common questions players have about obtaining these powers:
A: All quests begin in Rogue Town. Look for the All Might NPC (for One For All) and the Shigaraki Seller/Craft NPC (for Shigaraki powers). They’re usually in the central area but may move around during peak hours.
A: Absolutely not. All required materials (All For One Cells, Darkness Fragments, Soul Shards) drop exclusively from the summoned Shigaraki Boss. There are no alternative methods currently available.
A: No, it’s extremely weak. The version you get from All Might’s two quests is intentionally underpowered and meant to be a starting point. You must complete Deku’s longer questline to unlock its true strength.
A: Get Shigaraki first. For efficient progression, most experienced players recommend prioritizing Shigaraki as the power spike is more accessible and impactful for the grind required. One For All is better as a long-term goal.
A: It’s highly recommended for the Shigaraki Boss fight due to its 3 million HP. The One For All quests can be done solo but will be significantly more challenging and time-consuming.
A: Shigaraki: 2-4 hours with a good team. One For All: 6-10+ hours depending on your skill level and preparation. The full One For All questline is quite extensive.
A: Yes, but with conditions. Shigaraki offers excellent value for time invested and is great for progression. One For All is more of a long-term investment that pays off for dedicated players, especially My Hero Academia fans.
A: Currently, no. The game mechanics only allow you to have one primary power system active at a time. You can switch between them, but not use both simultaneously.
A: Likely yes. Based on the game’s update history and community feedback, the developers regularly balance powers. One For All is currently considered underpowered for its time investment, so buffs are possible.
A: Join the official Discord server or use the in-game chat system. Many players form LFG (Looking For Group) parties specifically for this boss fight.
After spending dozens of hours testing both power acquisition methods and helping countless players through the process, I can confidently say that both One For All and Shigaraki powers offer unique and rewarding experiences in Rogue Piece.
For the majority of players, I recommend starting with Shigaraki’s Decay powers. The straightforward boss-focused approach, immediate power benefits, and team-building aspects make it the perfect choice for efficient progression. Once you’ve mastered Shigaraki and built up your character, you’ll be much better equipped to tackle the extensive One For All questline.
For the dedicated My Hero Academia fans and players who love long-term character progression, One For All offers an incredibly satisfying journey that pays off with one of the most powerful abilities in the game. Just be prepared for a significant time investment.
Final Pro Tip: Before starting either power grind, make sure to check out the latest Rogue Piece QoL update for any new codes or changes that might affect your strategy. The developers are constantly updating the game, and staying informed will give you a significant advantage.
Remember to save this guide and bookmark it for reference as you progress through these exciting new powers in Rogue Piece. The My Hero Academia update has truly transformed the game, and mastering these abilities will place you among the elite players in the community.
