Where to Find the NPCs for My Hero Academia Powers
All the action for obtaining My Hero Academia powers happens in Rogue Town. This area serves as the central hub for the MHA update, with three key NPCs you’ll need to interact with:
- All Might NPC: Start your One For All journey here by completing his initial quests
- Deku Quest NPC: Continue your One For All progression with this character’s extensive questline
- Shigaraki Seller NPC: Exchange your hard-earned materials for Shigaraki’s Decay powers
You can’t miss these NPCs in Rogue Town – they’re usually crowded with players working on their MHA power progression. If you’re new to Roblox games, NPCs are characters with yellow or blue names that give quests and sell items.
How to Get Shigaraki Powers in Rogue Piece?
Shigaraki’s Decay powers offer a straightforward path to incredible strength in Rogue Piece. This combat style focuses on damage-over-time and crowd control, making it perfect for players who want to quickly boost their combat effectiveness without weeks of questing.
What Materials Do You Need for Shigaraki?
Before you can unlock Shigaraki’s powers, you’ll need to collect these specific materials:
- 25,000 Gems: The currency cost to purchase the power
- 1 All For One Cell: Extremely rare drop from the Shigaraki boss (about 0.25% chance)
- 5 Darkness Fragments: Uncommon drop from the Shigaraki boss (about 1% chance)
- 25 Soul Shards: More common drop from the Shigaraki boss (about 10% chance)
All these materials drop exclusively from the Shigaraki boss, so you’ll need to defeat this challenging enemy multiple times to collect everything you need.
How to Summon and Fight the Shigaraki Boss?
The Shigaraki boss is no pushover – this formidable enemy packs 3 million HP and hits hard. Here’s how to summon and defeat it:
- Craft a Darkness Spirit: Visit the Crafting NPC in Rogue Town to create this summon item
- Summon the Boss: Use the Darkness Spirit in Rogue Town to spawn Shigaraki
- Team Up: This boss is nearly impossible to solo – gather a team of 3-6 players
- Use High DPS Builds: Bring your strongest attacks to chip away at that massive HP pool
- Coordinate Attacks: Work with your team to avoid overwhelming the boss with too many attacks at once
The fight can take several minutes even with a full team, so come prepared with healing items and your best combat strategies. The boss has multiple attack phases, so stay alert and be ready to dodge powerful area-of-effect abilities.
Step-by-Step Guide to Unlock Shigaraki Powers
Follow these exact steps to get Shigaraki’s Decay powers:
- Gather Your Team: Find 3-6 players who also want to farm the boss
- Craft Darkness Spirits: Each player should craft multiple summon items
- Start the Farm: Take turns summoning the boss so everyone gets drop chances
- Collect Materials: Keep fighting until you have all required drops
- Return to Rogue Town: Visit the Shigaraki Seller NPC
- Make the Exchange: Trade your materials and 25,000 Gems for the power
Pro tip: Join a Rogue Piece Discord server to find farming groups and stay updated on any changes to drop rates or requirements.
How to Get One For All (Deku) in Rogue Piece?
One For All represents the ultimate quest for dedicated Rogue Piece players. This power requires significant time investment but rewards you with one of the most versatile combat styles in the game. The journey begins with a weak base version and evolves into the full power through extensive questing.
What Are the Requirements for One For All?
Before you can start your One For All journey, you’ll need:
- 10,000 Gems: Required to begin the questline
- Diamond Rank: A high-level player rank that shows your progression
- Access to Rogue Town: Where all the MHA quests begin
The Diamond rank requirement is the biggest hurdle for most players. This rank shows you’ve put significant time into the game and understand its mechanics. If you’re new to Roblox progression systems, you might want to start with easier goals first.
How to Reach Diamond Rank?
Reaching Diamond rank is a challenge in itself. Here’s what you need:
- 20 Sukuna’s Fingers: Dropped by the Sukuna boss
- 5 Venom Fangs: Dropped by the Sung Jin Woo boss
- 5 Knight Killers: Also dropped by the Sung Jin Woo boss
- 1 Million Cash: In-game currency
This means you’ll need to farm multiple bosses and save up a significant amount of money before you can even start the One For All questline. Many players recommend working on this rank gradually while you enjoy other aspects of the game.
Complete Quest Guide for One For All
Once you meet the requirements, follow these steps to get One For All:
- Talk to All Might: Find this NPC in Rogue Town to start your journey
- Complete Initial Quests: All Might will give you two starter quests:
- Defeat 10 players with 50,000+ bounty
- Defeat 25 Shigaraki bosses
- Get Base One For All: After completing these quests, you’ll receive the weak base version
- Find Deku Quest NPC: This character offers the main questline for full One For All
- Complete Extended Questline: This involves multiple quests with various requirements
- Unlock Full Power: Finish all quests to obtain the complete One For All ability
The base version of One For All is intentionally weak – think of it as a starter ability that proves you’re serious about mastering the full power. Don’t get discouraged if it doesn’t feel powerful at first!
How to Unlock Full Cowl Mastery?
Full Cowl mastery takes your One For All to the next level, unlocking the V and F skills. Here’s how to get it:
- Equip One For All: You must have the base power equipped
- Find Full Cowl NPC: Located in Rogue Town
- Complete Mastery Quests:
- Use Detroit Smash 200 times
- Defeat 25 Shigaraki bosses
- Receive Rewards: You’ll unlock V and F skills plus the One For All Suit accessory
The One For All Suit accessory provides impressive buffs:
- 2.5x Power multiplier
- 1x Strength boost
- 1x Defense boost
- 1x Sword boost
These bonuses make the grind worthwhile for dedicated players who want to maximize their combat effectiveness.
Shigaraki vs One For All: Which Power Should You Get First?
Many players wonder which MHA power to prioritize. Here’s a comparison to help you decide:
Shigaraki Advantages:
- Faster to obtain (no rank requirements)
- Better for early-to-mid game progression
- More straightforward farming process
- Excellent for team play and boss fights
- Decay abilities work well against groups of enemies
One For All Advantages:
- More powerful in late-game scenarios
- Better for PvP combat with burst damage
- Offers more skill variety with Full Cowl mastery
- Suits players who enjoy extensive questing
- Provides bragging rights for dedicated players
Recommendation: Get Shigaraki first. The power spike is more immediate, and you’ll need to farm Shigaraki bosses anyway for One For All quests. Once you have Shigaraki and some experience under your belt, then work toward the Diamond rank needed for One For All.
Pro Tips for Farming Materials and Completing Quests
Maximize your efficiency with these expert strategies:
- Join Farming Groups: Use Discord or in-game chat to find teams for boss farming
- Rotate Boss Summons: Take turns using Darkness Spirits so everyone gets drop chances
- Track Your Progress: Keep a count of Detroit Smash uses and boss defeats
- Use Active Codes: Check for Rogue Piece codes that might give gems or boosts
- Focus on One Power at a Time: Don’t try to grind both simultaneously – you’ll burn out
- Upgrade Your Gear: Better equipment makes boss fights and PvP much easier
- Time Your Sessions: Farm during peak hours when more players are available for teams
Remember that both powers require significant time investment. Set realistic goals and celebrate small victories along the way!
Frequently Asked Questions
Where do I find the NPCs for these powers?
All the My Hero Academia power NPCs are located in Rogue Town. Look for All Might to start One For All quests, the Deku NPC for advanced One For All progression, and the Shigaraki Seller to exchange materials for Shigaraki’s Decay powers. They’re usually in the central area of Rogue Town and are easy to spot due to the crowds of players around them.
How rare is the All For One Cell?
The All For One Cell is extremely rare with only about a 0.25% drop rate from the Shigaraki boss. This means you might need to defeat the boss 400+ times on average to get one. Join farming groups and take turns summoning to increase your chances. The low drop rate makes this the most challenging part of obtaining Shigaraki powers.
Can I solo the Shigaraki boss?
Soloing the Shigaraki boss is not recommended for most players. With 3 million HP and powerful attacks, this boss is designed for teams of 3-6 players. Only extremely high-level players with top-tier gear and maxed stats should attempt a solo run. For everyone else, teaming up is the smart approach.
What rank do I need for One For All?
You need Diamond rank to start the One For All questline. This requires collecting 20 Sukuna’s Fingers, 5 Venom Fangs, 5 Knight Killers, and 1 million cash. The rank requirement ensures players have significant game experience before attempting this advanced power.
Is the base One For All worth getting?
The base One For All you get from All Might’s initial quests is intentionally weak. It’s more of a proof of concept than a combat-ready power. However, it’s necessary to unlock the full version, so you’ll need to grind through it. Think of it as the first step on a longer journey rather than the final destination.
How do I unlock Full Cowl mastery?
To unlock Full Cowl mastery, you must first have the base One For All power. Then find the Full Cowl NPC in Rogue Town and complete two quests: use Detroit Smash 200 times and defeat 25 Shigaraki bosses. This unlocks the V and F skills plus the powerful One For All Suit accessory with its 2.5x power multiplier.
Which power is better for PvP?
One For All is generally considered better for PvP combat due to its burst damage potential and versatile skill set. The Full Cowl mastery adds even more options for player-versus-player scenarios. Shigaraki works better for PvE content like boss fights and mob clearing with its damage-over-time effects.
Conclusion
The My Hero Academia powers in Rogue Piece offer exciting new ways to play the game, whether you prefer Shigaraki’s straightforward decay abilities or One For All’s quest-driven progression. While both powers require significant grinding, they provide unique playstyles that can transform your Rogue Piece experience.
Start with Shigaraki for quicker results and easier progression, then work toward Diamond rank and the extensive One For All questline. Remember to join farming communities, use active codes, and take breaks to avoid burnout during the grind.
