Clair Obscur: Expedition 33 – Ono-Puncho 9999 Damage Guide

So you’ve run into Ono-Puncho in Gestral Village, and they’ve laid down a challenge: deal 9999 damage in one hit. While it might sound like a late-game flex, you can actually pull it off while you’re still in the area — if you’ve got the right setup.

Let’s break down exactly how to pull this off, using Maelle as your damage dealer.

The Rules of the Challenge

Before diving in, here’s how the challenge works:

• You only get one hit to land 9999 damage.
  
• Buffs like Gustave’s Powerful skill are allowed — they don’t count as “hits.”
  
• Free Aim Shots are okay too, as long as they’re from the same character doing the main attack.
  
• Debuffs and prep moves are fair game — you’re free to set the stage.
  

With all that in mind, Maelle is a perfect pick for this — especially if you’ve just won the Gestral tournament using her.

⚙️ How to Deal 9999 Damage Using Maelle

️ The Setup

Here’s a sample setup to make this work:

Maelle:

• Weapon: Medalum (best option) — starts her in Virtuose Stance for +200% Percee damage and lower AP cost
  
• Alternative: Any weapon with 250+ Power (works too, just slightly harder)
  
• Luminas:
  
  • Marking Shots (required) – 20% chance to apply Mark on Free Aim Shot
    
  • Critical Burn (optional) – Boosts Crit on burning enemies
    
  • Roulette (optional but helpful if not using Medalum)
    
• Stats: High Luck for Crit chance; aim for at least 19 Luck if possible
  
• Skill: Percee – your big-hitting move
  

Gustave:

• Buff Maelle with Powerful skill
  

Lune:

• Use an Energy Tint on Maelle (if needed to refresh AP during setup)
  

Strategy – Step-by-Step

1. Buff Maelle with Gustave’s Powerful Skill
   (Only necessary if you don’t have Medalum or Virtuose Stance active)
   
2. Use an Energy Tint on Maelle (Optional, for AP recovery if she misses Marks)
   
3. Use Free Aim Shot with Maelle until Mark is applied
   ⚠️ Do not hit again once Mark is applied! The next hit must be your Percee or the Mark is wasted.
   
4. Use Percee
   With Virtuose Stance or a lucky 200% Roulette proc, plus a Crit, you should land the 9999.
   

Important: You’ll probably need to retry a few times due to RNG:

• Mark needs to apply within a few AP
  
• Percee needs to Crit
  
• Roulette (if using it) must land the 200% multiplier
  

Maelle’s Build That Works

In testing, a Level 16 Maelle with a Level 7 weapon had the following stat spread:

• Vitality: 0
  
• Might: 10
  
• Agility: 5
  
• Defense: 5
  
• Luck: 19
  

This is enough to hit the 9999 mark under the right conditions.

Reward for Beating Ono-Puncho

When you successfully land the 9999 damage, Ono-Puncho rewards you with a cosmetic — no gameplay buffs here, but hey, it’s all about the bragging rights.

No pressure to get it done early — come back later if you’re struggling, but it’s fun to test your build mid-game and see how far you’ve come.
