🥊 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)
- Marking Shots (required) – 20% chance to apply Mark on Free Aim Shot
- 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
- Buff Maelle with Gustave’s Powerful Skill
(Only necessary if you don’t have Medalum or Virtuose Stance active) - Use an Energy Tint on Maelle (Optional, for AP recovery if she misses Marks)
- 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. - 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.
