As you navigate the many dungeons in Clair Obscur: Expedition 33, you’ll eventually come across Nevrons who don’t immediately try to fight you. Instead, these puzzled and passive Nevrons will often ask for your help. Taking the time to complete their requests is worth it—not only will you earn some great rewards and unlock the Aiding the Enemy Achievement/Trophy. Below, we’ll show you where to find each of these Nevrons and what you’ll need to do for them.
All Nevron Locations
There are 10 Nevrons that need your help in Clair Obscur. Most of these quests are pretty straightforward: you’ll find the Nevron, they’ll ask you to retrieve something, and once you bring it back, they’ll reward you. Just be careful—not attacking them is crucial. If you choose to fight them, you’ll be locked out of the achievement and reward, which is better saved for a second playthrough in New Game+.
Jar

You can find Jar at the Abandoned Expedition Camp in Spring Meadows. He’s just sitting there, confused and quiet. Talk to him, and he’ll mention a need for Resin, which you can find a bit further into the area. Once you have it, bring it back to him, then shoot the tip of his weapon to complete the task.
Reward: Healing Tint
Démineur

Head to Noco’s Hut in the Flying Waters region. When you reach the area that leads to the ship, look to your right to find a small tunnel. Inside, you’ll find Démineur, who’s missing a mine from his setup. Hop across the platforms behind him until you reach the other side, where the Intact Mine is located. Return to Demineur and hand him the mine.
Reward: The Deminerim.
Bourgeon

Bourgeon appears as a small, white Nevron in the aptly named The Small Bourgeon area. He’s looking for a Bourgeon skin, which you can get by defeating one of the optional Bourgeon-type Nevrons. A good one to hunt is in Coral Cave, back in Flying Waters. After you return the item, reload the area and talk to him again.
Reward: Colour of Lumina.
Hexga

Find Hexga just before the flag in the Stone Wave Cliffs: Tide Caverns. He wants you to collect three specific rocks from further inside the caverns. It’s a simple fetch quest, but well worth it.
Reward: Auto Shell Pictos.
Troubador

In the Stone Quarry, located east of the Forgotten Battlefield, you’ll come across Troubador at the back of the area. He won’t ask for an item, but instead challenges you to complete three performance trials. Succeed in each one, then speak with him again.
Reward: Healing Parry Pictos (Level 10).
Portier Core

Just inside the entrance of the Esoteric Ruins, you’ll spot a strange being called Portier Core. It appears inactive at first, but if you explore deeper into the maze behind it, you’ll find a pile of wooden boards. Bring them back to complete the quest.
Reward: Protecting Heal Pictos.
Water Fountain

This one’s a bit different. In Red Woods, you’ll find a strange Water Fountain that asks for Chroma, and it’s hungry. You’ll need to donate a total of 88,000 Chroma across four tiers—first 3,000, then 10,000, then 25,000, and finally 50,000.
Reward: Recovery Pictos.
Danseuse Teacher

In Frozen Hearts, you’ll meet the mysterious Danseuse Teacher. She doesn’t want an item—she wants you to prove your skill. You’ll have to survive a parry sequence of about 20 attacks of varying speeds without a single failure. If you manage to complete the challenge, she’ll reward you.
Reward: Danseuse Outfit (Lune).
Chalier

Chalier is found in the Floating Cemetery, and his quest has a bit more moral weight. He’ll ask for your advice on what weapon he should use, then challenge you inside. After defeating him, you’ll be given a choice—end his life or spare him. You must choose to end his journey in order to receive the reward.
Reward: Auto Powerful Pictos.
Blanche

Blanche can be found at The Fountain, but she won’t ask for help right away. Instead, she appears after you’ve completed at least six other Nevron quests. Once you’ve done enough, speak to her again and she’ll give you the final and most generous reward.
Reward: x100 Colour of Lumina.
After you receive the final reward from Blanche, the Aiding the Enemy trophy/achievement will shortly pop up.
The other part in Clair Obscur that you should not sit upon is getting all the Mime locations in the game. Check our guide in case you are having trouble locating and defeating these.
