Unlocking One For All (OFA) and Shigaraki powers in Rogue Piece is one of the biggest goals for players aiming to reach end-game strength. These two abilities—pulled straight from the My Hero Academia universe—offer some of the strongest combat kits in the game, but they also come with two very different playstyles and two completely different grinds. This guide breaks down every requirement, every quest step, every material, and every farming method needed to obtain both powers efficiently. Whether you’re preparing to summon the Shigaraki boss, farming rare drops like the All For One Cell, or working through All Might’s and Deku’s long questline for full One For All, this walkthrough gives you everything you need to get both abilities with zero confusion.
- Shigaraki — easier: spawn the Shigaraki boss (Darkness Spirit summon), farm its drops (All For One Cell, Darkness Fragments, Soul Shards) and buy the Shigaraki combat technique from the Shigaraki NPC in Rogue Town. Boss has very high HP (≈3,000,000) so bring a team.
- One For All (Deku) — longer: talk to All Might to unlock the base OFA, then complete Deku’s questline (multiple quests + requirements such as gems and rank) to unlock full One For All, plus extra quests to unlock V & F skill variants. Expect to need ~10k gems and Diamond+ rank, plus boss farming for some steps.

Where to go / NPCs
All main NPCs tied to these powers are located in Rogue Town:
- Shigaraki Seller NPC (buys the technique once you have the items).
- All Might NPC (starts OFA quests).
- Deku / One For All Quest NPC (finishes the Deku questline to get the full One For All).
Shigaraki — full deep guide
What you need (per guide)
- 25k Gems (cost to purchase the technique).
- 1 All For One Cell — very rare boss drop (≈0.25% reported).
- 5 Darkness Fragments — low % drop (≈1% reported).
- 25 Soul Shards — higher chance (≈10% reported).
All three drop from the Shigaraki boss. After collecting required materials you can purchase Shigaraki from the Shigaraki Teacher in Rogue Town.
How to spawn the Shigaraki boss
- Craft a Darkness Spirit via the Crafting NPC (Craft NPC) — this is the summon item used to call Shigaraki.
- Use the Darkness Spirit in Rogue Town to summon the boss. The boss reportedly has ≈3,000,000 HP, so it’s best to team up if undergeared.
Boss fight & drops strategy
- The boss is big HP and likely has multi-phase attacks — bring players who can chunk HP quickly (high damage AoE or burst specs).
- Drop rates: All For One Cell ~0.25%, Darkness Fragment ~1%, Soul Shard ~10%. That means expect many clears — join a farming party or rotate maps with friends.
Buying & unlocking
- After collecting materials and paying gems, interact with the Shigaraki Teacher to purchase/unlock the combat technique.
Practical tips
- Bring Haki / high DPS specs — boss HP is huge. If you don’t have high DPS, coordinate with a group or use summon orbs/items to speed the fight.
- Farm in sessions: queue with a few friends and do repeated summons — drop rates are low; a 5–6 person team will clear faster and increase personal efficiency (you still need your own drops).
- Sell/convert extra drops only if the game supports it — otherwise hoard until you can buy.
One For All (Deku) — full deep guide
High-level steps
- Talk to All Might in Rogue Town and complete his two starter quests — this unlocks a base version of One For All. (Base version is weak.)
- Talk to Deku and complete his longer questline to unlock the complete/true One For All. The Deku questline is more involved/tedious.
- Additional quests (Full Cowl / V & F skills): interact with the Full Cowl NPC and complete tasks such as Detroit Smash 200 times and repeat Shigaraki boss kills to unlock extra skill variants (V and F).
Requirements & costs (reported)
- 10,000 Gems and Diamond+ rank to begin the OFA questline (these are the stated requirements to access the OFA teacher quests).
Quest specifics (reported by community guide)
- Example tasks listed (reportedly):
- Quest 1 (All Might): Defeat 10 players with 50K+ bounty (PvP task).
- Quest 2: Defeat 25 Shigaraki boss (boss farming requirement).
- Full Cowl unlock: Detroit Smash 200 times (Z skill count) + defeat 25 Shigaraki boss again for additional unlocks.
These are the kinds of grind objectives you’ll encounter — they mix PvP, boss clears, and repeat action counts.
Why Deku is more grindy
- Deku / OFA is more time-consuming because of multiple quest steps requiring PvP kills, boss clears, and large gem/rank requirements. Many players recommend unlocking Shigaraki first for quicker ROI and progression.
Practical recommendations for OFA
- Be Diamond rank or higher before attempting Deku quests to avoid repeated failures or to meet the gated requirement.
- Complete PvP bounty tasks by seeking out high-bounty players or grouping with friends (coordinate to swap bounty tags if needed).
- Track progress: Detroit Smash counts can be slow — make a rotation / macro of questing activities (boss runs interleaved with PvP) to keep progression efficient.
Suggested builds / best usage
- Shigaraki: plays like a DoT/decay-style spec (decay, crowd control). Best paired with high sustain or burst teammates that can finish the boss quickly. Use Shigaraki for early-to-mid progression if you need a reliable damage-over-time and utility spec.
- One For All (Deku): historically a burst/melee combo (Detroit Smash-style moves). Best for single-target burst and PvP if you invest the grind for full OFA and Full Cowl variants. V & F skills (Full Cowl variants) increase utility but require extra quests.
Farming plan
- Prep session: get a party of 3–6 players, ensure everyone has revival / healing items, and at least one high DPS.
- Spawn Shigaraki repeatedly (Darkness Spirits) — rotate use among party members so everyone gets a shot at drops. Expect many clears for the rare All For One Cell.
- Do bounty/PvP quests (for OFA) as you go — look for 50k+ bounty targets or arrange friend duels to fulfill the count faster.
- Use codes / events to top up gems or summon orbs when possible — redeem current Rogue Piece codes to reduce gem grind.
Known caveats & things to watch
- The community notes that base OFA is weak and the full questline is long; evaluate whether you want the time investment.
- Drop rates for crucial items are low, expect significant grind for All For One cells and Darkness Fragments.
- The devs may rebalance costs/requirements in future patches — check patch notes or the game’s Discord for changes.
Quick FAQ
Q: Which should I get first — Shigaraki or One For All?
A: Shigaraki — easier to obtain and gives useful progression power quickly. Deku requires more grind and rank/gem gating.
Q: How rare is the All For One Cell?
A: Community guides report ~0.25% drop, so expect many boss clears.
Q: Can I solo the Shigaraki boss?
A: Not recommended unless you are very high level and high DPS; the boss has ~3,000,000 HP. Team up.
