How to Break Paint Spikes in Clair Obscur: Expedition 33
As you explore the world of Clair Obscur: Expedition 33, youโll find all kinds of loot scattered around โ gear, Pictos, and even items dropped by tough enemies. But some of the rarest stuff? Thatโs hidden inside Paint Spikes โ those big blue-lined rocks youโll see standing out in almost every area.
To break them open, youโll need a special skill called Paint Break. Hereโs how to get it and how to use it.

How to Get the Paint Break Skill
You canโt just go smashing Paint Spikes from the start. First, you need to unlock the Paint Break skill โ and to do that, youโll need to track down Lost Gestrals.
Hereโs the step-by-step:
- Find 4 Lost Gestrals
These friendly little NPCs are scattered all over the continent. When you talk to one, theyโll return to your camp automatically. - Return to Sastro
After you’ve rescued at least four Gestrals, head back to your camp and talk to Sastro. Heโll reward you with the Paint Break skill.
Pro tip: By the time you reach Act 2 and unlock the Esquie ability to swim through Corals, youโll have easy access to enough areas to find four Gestrals.

Where to Find Sastro
Sastro is always hanging out in your camp, which you can return to anytime from the overworld.
Hereโs how to find him:
- Enter your camp and walk past Esquie.
- Head to the left path, not the one leading to the Curator.
- Go between the rocks until you see some wooden crates and a white sheet.
- Take a left at the sheet โ Sastro will be straight ahead.
Each time you return a Gestral, Sastro gives you a reward, so itโs worth checking in regularly.
How to Use Paint Break
Once youโve unlocked Paint Break, your basic attack outside of combat will get a small upgrade.
To use it:
- Walk up to a Paint Spike (those tall, blue-lined rocks).
- Line it up within range of your basic attack.
- Hit it โ and watch it shatter!
Right where the rock was, thereโs usually a rare item, Picto, or gear waiting for you. Itโs always worth the effort.
Donโt forget: After unlocking Paint Break, go back to earlier areas. There are Paint Spikes hiding lots of powerful loot thatโs often better than anything else youโll find in that region.
And thatโs it! Unlock Paint Break, smash every blue-lined rock in sight, and score some of the best hidden rewards in the game.
