Clair Obscur: Expedition 33 has an interesting approach to weapons, and players will find a lot. All weapons can be upgraded as much as characters can level up in the game, either by using upgrade materials or by finding the same weapon in the game, be it from a boss or by buying it from one of the few shops in the game.

10
Algueron
Mandelgo’s Shop In Old Lumiere
The Algueron can be acquired for Sciel easiest by buying it in Old Lumiere from Mandelgo’s Shop. It’s an ice-based weapon, and the best qualities will help with Free Aim. If Sciel has Foretell cards stacked or goes into Twilight Mode, the damage will increase.
Also, basic attacks with the weapon can generate her Foretell cards, and Sciel overall is like a tarot master who harnesses Sun and Moon cards to become powerful.
9
Corpeso
Fight Random Enemies In Dark Shore
The Corpeso appears in the later game, so it’s more for Verso rather than Gustave. Players have to fight the weird cloaked hand enemies on the Dark Shore, which look like missing from Dark Souls. Verso has an innate talent called Perfection that, when raised, will increase his attack.
The Corpeso weapon is fire-based and can increase Burn output and damage throughout its upgrade tiers. Burning enemies is one of the best status effects in Clair Obscur: Expedition 33.
8
Facesum
Fight Chromatic Boucheclier On Isle Of The Eyes
The Facesum can be found on Isle of the Eyes and can be won if players defeat Chromatic Boucheclier, who is not that hard with the right setup. Even though it isn’t infused with the fire element internally, it can increase Burn damage.
Players can stack Burn if they pair Verso’s Corpeso weapon with Maelle’s Facesum for an easy way to victory in Clair Obscur: Expedition 33.
7
Joyaro
Fight Ultimate Sakapatate In Endless Night Sanctuary
The Joyaro can be found in the Endless Night Sanctuary, and players have to defeat one of the game’s harder bosses, Ultimate Sakapatate, to earn it. The weapon is infused with lightning, and it’s for Monoco, who uses a wheel system to upgrade attacks based on mask, and he’s also like a Blue Mage from Final Fantasy as he learns from monsters.

Leveling up Attributes in Clair Obscur: Expedition 33 is the best way to improve each character’s stats, and these are the ones to focus on.
With Joyaro, Monoco will start with Almighty Mask equipped, which can enhance all power for his attacks, especially upon consecutive attacks. It can also be used to Break enemies in Clair Obscur: Expedition 33.
6
Lithelim
Fight Random Enemies In Lumiere
The Lithelim is a weapon for Lune that can be found when players reach the ruined state of Lumiere at the end of the game. It’s infused with the dark element, which is unusual since most of Lune’s spells aren’t based on the dark or light elements besides her healing magic.
That’s why this weapon is handy as it can generate light and dark Stains, but it’s most useful for players looking to strike enemies with dark-based attacks. Stains can be used for spells that generate into Lune’s weapon of choice in Clair Obscur: Expedition 33.
5
Litheson
Fight Clair Obscur In Inside The Monolith
The Litheson is another weapon for Sciel, and this can be found Inside The Monolith, the game’s second-to-last big dungeon. There is an optional boss in the fake city of Lumiere called Clair Obscur, funnily enough, which consists of three challenging enemies.
Behind them is the Litheson weapon on a table, which is good for speeding up allies or slowing down enemies. It depends on Sciel’s deck of cards, but either way, it’s a good weapon for the party to buff them or debuff enemies.
4
Medalum
Compete With Maelle In Gestral Village’s Arena
The Medalum is a very early weapon for Maelle that players can win if they participate with her during the tournament arc in Gestral Village. Using it will automatically put her in Virtuose Stance, which does 200% more damage.
Stances are Maelle’s specialty, and Virtuose is the best, so players can begin a battle quickly to do some high damage based on pure attacks and by stacking Burn charges. Get the Medalum early and stick with upgrading it to turn Maelle into an absolute beast.
3
Saperim
Fight Random Enemies On A Beach East Of Sirene
The Saperim can be acquired if players sail to a beach and fight some random group of enemies east of Sirene, which is in about the middle of the world. This weapon is lightning-based and can generate lightning and light Stains, which is good, but it’s best for enhancing Gradient Attacks and Gradient Counters.

With six battle-ready characters, who among them reigns supreme in Clair Obscur: Expedition 33?
Gradient Attacks are like Limit Breaks from the Final Fantasy series, and they are some of the strongest attacks in Clair Obscur: Expedition 33. Gradient Counters are rare Parry options that will appear later in the game.
2
Sireso
Fight Chromatic Greatsword Cultist In Sirene
The Sireso is an excellent weapon for Verso if players face the Chromatic Greatsword Cultist optional boss in Sirene, which shouldn’t be too hard at this point in the game. This blade for Verso will take away his Perfection bonuses for himself and instead have them improve the party.
Like Sciel’s Litheson weapon, the Sireso is great for the party, and it can even lessen the AP cost of support-type skills, which Verso has a few of.
1
Urnaro
Fight Chromatic Glaise On Sky Island
The Urnaro is a very special weapon that players can acquire by fighting Chromatic Glaise on Sky Island. The weapon is earth-based, and it can switch to the Almighty Mask if players Break an enemy with Monoco.
When this happens, all allies will gain two AP, which is a nice bonus, and on top of that, Break-based damage will increase for Monoco. To get the most out of Breaks, a crucial status effect in the game, players should make a good Break-based build for Monoco starting with Urnaro.
