Do you want to take down Ono-Puncho with a clean 9,999 damage in just one instance? This is actually very much possible—and in fact, very fun—once you figure out how to manipulate the game’s mechanics and get Maelle set up properly. Here’s the rundown for that straightforward and elegant win.

Understanding the Challenge Rules

Before diving into the strategy, let’s get the core rules out of the way:

• Only one attack is allowed on Ono-Puncho.

• Buffs like Gustave’s “Powerful” don’t deal damage, so they don’t count as a hit.

• Free Aim Shots don’t break the rule as long as they’re used by the same character who will land the final blow (in this case, Maelle).

• Debuffs and buffs can be set up before the final hit, giving you plenty of prep time.

Maelle as the Damage Dealer

Having Maelle is truly the best character option for this hit-one-time challenge. She comes into his sights just after the tournament arc. Not to mention, you won’t be going far from Gestral Village now.

Core Tactic:

1. Buff Maelle using Gustave’s Powerful skill.

2. Land a Free Aim Shot with Marking Shots Lumina to apply Mark to the enemy.

3. Once marked, use Maelle’s Percee skill for a devastating hit.

Why Medalum Helps (But Isn’t Mandatory)

Using the Medalum weapon gives Maelle a huge advantage:

• Automatically starts her in Virtouse Stance, which boosts Percee by 200%.

• Cuts AP cost for Percee from 5 to 2.

How to Get Medalum:

• Win the tournament fight as Maelle against The Stranger (Sciel), or

• Defeat Golgra at the Chief’s House in a duel.

If you don’t have Medalum—don’t worry! As long as Maelle’s weapon has Power ~250 or more, she can still reach 9999 damage. You can also use her Last Chance skill to enter Virtouse Stance without needing Medalum.

Optimal Loadout for Maelle

Weapons:

• Best Option: Medalum

• Alternative: Any weapon with enough Power (250+)

Must-Have Lumina:

• Marking Shots: 20% chance to apply Mark with Free Aim (essential)

• Roulette: 50% chance for either 50% or 200% damage (mandatory if you lack Virtouse Stance)

Optional Lumina (for added boost):

• Burning Shots: Adds Burn on Free Aim

• Critical Burn: Increases Crit Chance if enemy is burning

Pictos:

• Focus on Critical Rate to reduce reliance on RNG.

Team Composition Tips

• Ensure the other two team members act before Maelle.

• Give them First Strike Lumina if needed.

• Their role is just support—no damage to Ono-Puncho from them!

Step-by-Step Execution

1. Gustave buffs Maelle using his “Powerful” skill.

2. (If not using Medalum) Use Lune’s Energy Tint on Maelle to help with AP recovery.

3. Maelle uses Free Aim Shot repeatedly until Mark is successfully applied.

4. The moment Mark lands, immediately follow up with Percee.

(Avoid extra attacks—reapplying damage can wipe the debuff.)

Troubleshooting: When You Fall Short

Still not hitting 9999? Try these adjustments:

• Raise Maelle’s Might and Luck through stat distribution.

• Level up her weapon for better base damage.

• Retry the run until you land all necessary buffs and procs.

Things to Watch Out For (RNG Factors)

If you’re not using Medalum or Last Chance, these things can throw a wrench into your plan:

• AP Management: You need 5 AP for Percee if you’re not in Virtouse Stance.

• Mark Application: 20% chance per Free Aim shot—could take a few tries.

• Roulette RNG: You’ll need that 200% roll to hit 9999.

• Critical Hits: Crits help push your damage higher. Boost Luck and equip high Crit Rate Pictos.
