The One Punch Man collaboration is one of the most ambitious crossovers Legend of Mushroom has released so far. It introduces a full event hub, multiple gacha systems, mini-games, exclusive heroes, artifacts, costumes, mounts, and several reward tracks running at the same time.

If you want to make the most of this limited-time collab, this guide breaks down every event, how they connect, and what players should prioritize depending on their playstyle.

Overview of the Collab Event

All major events run from November 27 to December 3.
Almost everything feeds into the Heroic Journey system, which is the main hub of the collaboration.

The Heroic Journey includes:

• Hall of Heroes
• Promotion Path
• Crisis Event
• Hero Command Center

These four systems use Hero Tokens and Hero Mission Cards as their core currencies.

1. Hall of Heroes

This is the ranking and progression event based on Prowess.

What You Do:

• Collect Hero Tokens from collab activities.
• Increase your Prowess score.
• Climb the leaderboard.

Rewards:

• Limited titles
• Exclusive avatar frames
• Various premium items

Tips:
Consistent daily participation is the key. Small, steady gains outperform trying to rush everything on the final day.

2. Promotion Path (Collab Battle Pass)

The Promotion Path acts as a battle pass specifically for the collaboration.

How It Works:

• Hero Tokens increase your Promotion Path experience.
• Reaching certain levels rewards mission cards, materials, and collab items.
• There is a free track and an advanced paid track.

F2P Focus:

• Claim all free tiers.
• Save Hero Tokens early so you can push deeper into the pass throughout the week.

Light/Medium Spenders:

• Unlock the premium track if the exclusive rewards appeal to you.
• The collab rewards tend to be more valuable than usual event passes.

3. Crisis Event

The Crisis Event is a prize-draw system using Hero Mission Cards.

Rewards Include:

• Mythic artifact: Punch of Triumph
• Artifacts like Speed of Death and Cryo Shield Flame
• Back accessory: Punching Storm

Key Mechanic:

• If you draw 100 times, you receive a guaranteed top prize.
• This removes the frustration of bad luck streaks.

Recommendation:
Save your Hero Mission Cards until you know whether you want to go for the guaranteed prize or try your luck in smaller portions.

4. Hero Command Center (5-Floor Reward Tower)

A multi-layer reward tower that resets once completed.

Structure:

• Five floors total
• Each floor has one main reward
• Drawing the floor’s promotion reward lets you move to the next floor
• After finishing floor 5, the system resets back to floor 1

Important Details:

• The grand prize on the top floor is the mount Best Buddy.
• You can obtain the top reward a limited number of times before it gets replaced with Red Soul Selection 2.
• Early top-floor completions also give additional realm rewards.

Strategy:
High spenders can chase multiple mount copies.
F2P should consider this a bonus system and not a priority sink.

5. Mosquito Buster Mini-Game

A simple reaction-based mini-game included for fun and small rewards.

Objective:

• Swat as many mosquitoes as possible before the timer ends.
• Higher score = better rewards.

It’s a light distraction but easy to complete daily.

6. Meow Fortune Cat (Gem Rebate System)

This event favors players who plan to spend gems.

How It Works:

• Recharging gems grants Fortune Draws.
• Using these draws returns 1–3x gem rebates.
• Best used when you plan to purchase collab packs or battle pass upgrades.

Worth it if you already planned to spend.

7. Union of Heroes (Daily Login)

A simple check-in event that provides free collab items.

Rewards include:

• Event-exclusive outfits
• Avatar frame
• A collab-themed Avian

Make sure you log in every day to avoid missing these free cosmetics.

8. Limited Star Hero Pool

A collab-only hero summoning pool.

Key Rules:

• Only collab-exclusive draw items work here.
• Permanent pool tokens cannot be used.
• Collab heroes include King, Hellish Blizzard, and others.

If you collect heroes, this is the pool to save your event-specific resources for.

9. Heroic Rescue Costume Pack

Time-limited costume packs offering collab-exclusive outfits.

Some of these outfits come with stat bonuses, so check each pack before buying.

10. Mightiest Hero Arrives (Server Event)

A collaborative server-wide task board.

How It Works:

• All players submit event items.
• Submissions fill a hero poster.
• Completing the poster unlocks server-wide rewards.

Active servers benefit heavily from fast completion.

11. Shrimi Association

A deeper progression system tied to facilities and recruiting Pals.

What You Do:

• Complete daily commissions to earn Funds and Pal Points.
• Upgrade facilities within the association.
• Recruit Pals for added benefits.
• Spend event tokens in the Association Shop.

Shop Items Can Include:

• Collab outfits
• Breeding item: Power Part
• Collab Avian
• Additional event resources

This is one of the most rewarding F2P-friendly parts of the collab.

12. Thanksgiving Event

Running alongside the collab is a Thanksgiving bonus.

Reward Highlight:

• A special Thanksgiving Magic Lamp – Turkey appearance.

Simply meet the login and participation requirements to claim it.

The Legend of Mushroom x One Punch Man collaboration is loaded with content. Whether you’re a collector, a min-max player, or just here for cosmetics, there’s value in every corner of the event.

Daily participation is the key to maximizing rewards, and understanding how Hero Tokens and Mission Cards flow through the Heroic Journey system will make your progression smooth and efficient.
