Mamull’s Painted Stone Challenge: How I Beat the Scam in Genshin Impact

When I first stumbled southwest of the Masters of the Night-Wind Statue of the Seven, I thought Mamull was just another colorful NPC with a silly game. It was 2026, and Natlan still hums with secrets, but this one felt different. A wooden platform. A row of boxes. A Hued Monetoo glowing nearby. And a young Iktomisaurus watching from a podium like it knew something I did not. I had no idea I was about to lose Mora, lose my patience, and then win an achievement called Alert And On Guard. If you are staring at the same painted stones and wondering why every color choice feels wrong, here is how I finally turned Mamull's trick against him.

The Innocent-Looking Setup

At first, the Painted Stone Challenge looks like a simple matching game. Mamull asks you to paint a stone so it matches the colors of the boxes around you. You interact with the Hued Monetoo, splash color onto the stone, and wait for the result. For the first few rounds, I actually believed I was good at it. One stone, one color, one quick win. The platform is not huge, so I kept circling it, checking boxes, and feeling clever.

Round	What I Did	What Happened
Early rounds	Painted one stone to match nearby boxes	I won, or at least I thought I did
Later rounds	Painted more stones, paid Mora	Mamull changed the rules
Final round	Painted five stones	I lost no matter what

Then the final challenge arrived. The stakes jumped. Mamull wanted Mora, and he wanted me to paint five stones. I picked colors carefully. I matched every box I could see. It did not matter. I lost. I paid again. I lost again. That was the moment the game stopped being cute. It became a con.

Why You Cannot Win Fairly

Here is the trick: Mamull's game is rigged. The young Iktomisaurus on the podium is not just decoration. It is part of the deception. Mamull can claim you failed because of the colors, but the real problem is that he never intends to let you win. I felt foolish for trusting him, but I also felt angry. In Genshin Impact, not every challenge is solved by hitting harder or painting better. Sometimes you have to look at who is caged, who is watching, and who is lying.

The Real Solution: Free the Young Iktomisaurus

This is the part I wish I had known before spending so much Mora. You do not beat Mamull by painting stones. You beat him by exposing him. The actual solution is to rescue the captive young Iktomisaurus and bring its parent into the game. Here is the exact sequence I followed:

1. 🦎 Find the young Iktomisaurus locked in a cage on the left side of the challenge area. It is easy to miss if you are focused on the boxes.

2. 🔑 Look for a glowing key on a nearby podium beside a lantern. Pick it up.

3. 🗝️ Use the key to free the young Iktomisaurus from the cage.

4. 🦖 Transform into a Saurian. This is important. You need to speak with the adult Iktomisaurus standing behind Mamull.

5. 💬 After you have lost to Mamull twice, tell the adult Iktomisaurus that its child is free. The parent understands the scam immediately.

6. 🔁 Return to Mamull and start the challenge again.

Once the adult Iktomisaurus is involved, the balance shifts. You can paint any color. You can make mistakes. It does not matter. The adult Iktomisaurus ensures that you win, and Mamull cannot cheat his way out of it. I laughed when the victory screen appeared. It felt less like a game reward and more like justice.

Claiming Alert And On Guard

After you win the rigged challenge with the Iktomisaurus parent watching, you earn the Alert And On Guard achievement. That achievement is the real prize. It is not just a trophy. It is proof that you paid attention, freed an innocent creature, and refused to be scammed. If you are a completionist in 2026, this is still one of those Natlan secrets worth checking off your list.

What I Learned from Mamull

Genshin Impact often hides its best stories behind silly mini-games. Mamull's Painted Stone Challenge is a perfect example. On the surface, it is about colors and boxes. Underneath, it is about trust, deception, and a trapped baby dinosaur. I went in expecting a quick puzzle. I came out with a lesson: when a challenge feels impossible, stop playing by the cheater's rules. Look for the cage. Find the key. Talk to the creature behind the curtain.

Here is a quick recap for anyone who wants to save time:

Step	Action	Why It Matters
1	Locate Mamull southwest of Masters of the Night-Wind Statue of the Seven	Starts the challenge
2	Play until you lose twice	Unlocks the dialogue path with the adult Iktomisaurus
3	Find and free the young Iktomisaurus	Exposes Mamull's deception
4	Transform into a Saurian and speak to the adult	Gains an ally who guarantees your win
5	Return and complete the Painted Stone Challenge	Earns Alert And On Guard

Even in 2026, with new regions and new systems arriving in Teyvat, old challenges like this still teach the same thing. Exploration is not just about treasure chests. It is about noticing details. It is about asking why a stranger wants your Mora. And it is about freeing a small Iktomisaurus when nobody else will.

If you are stuck on Mamull, do not waste another coin. Free the young one. Talk to the parent. Then watch the scammer lose. That is how I finally beat the Painted Stone Challenge, and that is how you can too.
