Introduction to Cellchemist Weapons

This guide focuses on the best weapons available in the game Clair Obscur: Expedition 33, which is sometimes referred to by players as 'Cellchemist.' Finding and understanding the optimal weapons for each character is crucial for maximizing your team's effectiveness and progressing through the game. The effectiveness of a weapon often depends on character builds, skill synergies, and the specific role a character plays in your party.

Best Weapons for Sciel

Sciel's gameplay revolves around managing Sun and Moon charges to trigger and extend her powerful 'Twilight' state, which significantly boosts her damage output and 'Foretell' buildup.

  • Tesseron: This is highlighted as a favorite weapon for Sciel due to its ability to extend her powerful 'Twilight' state. Its Level 10 perk extends 'Twilight' by one turn, and its Level 4 perk allows for even further extension by strategically using moon charges while in 'Twilight'.
  • Best Weapons for Maelle

    Maelle has access to weapons that can enhance her offensive capabilities, defensive utility, and unique stances.

  • Medelum: Considered the best weapon for most Maelle players.
  • Barrier Breaker: This weapon offers a unique defensive and offensive synergy. It steals shields from enemies and applies them to Maelle. Additionally, Maelle switches into her 'virtuoso stance' whenever she destroys a shield. Its Level 20 perk can be useful for removing multiple shields at once if an enemy is marked. Barrier Breaker deals void damage, making it particularly effective against certain enemies and bosses resistant to other damage types. It is obtained during the main story and is impossible to miss.
  • Yeum: This weapon synergizes with Maelle's shield mechanics. With Yeum, Maelle gains a shield whenever the 'shell' status is applied, and she also gains an action point when a shield is applied. To fully leverage these perks, players should use specific 'Luminina' like 'protecting shots' or 'protecting attacks' to trigger 'shell' as frequently as possible.
  • Best Weapons for Lune

    Lune's weapon choices support various playstyles, including damage dealing and healing, often interacting with her 'stain' mechanic.

  • Minan: This weapon is dropped by the Chromatic Chaplier in the Crows region.
  • Trebushim: A good early-game option for Lune, especially for players learning her 'stain' mechanic. It grants a random stain on free aim shots, provides an action point when consuming stains, and generates two stains with a base attack. Trebushim is obtained from the catapult and Ranger Sakapathots encountered in the Ancient Sanctuary during the main story.
  • Potter, Retom, and Benism: These are strong choices if you primarily play Lune as a healer.
  • * Potter and Retom both generate an extra light stain when using a healing skill. Potter also applies the 'slow' status to a random enemy and allows Lune to generate light stains by using base attacks. * Retom additionally provides a free ice stain at the start of every turn and allows Lune to play again for free when using a healing skill that consumes stains. * Benism also grants a free extra turn.
  • Scaver: A more advanced weapon that suits a specific playstyle focused on building up significant damage boosts. It generates special 'dark stains,' and consuming four of them can boost the damage of any skill by an extra 300% (4x damage). Scaver is acquired by clearing the boss in the Falling Leaves region.
  • Litholm: Similar to Scaver, Litholm also generates light stains and returns an action point when consuming them, making it more versatile. It deals void damage, which can be useful against tough enemies and bosses resistant to other damage types. This weapon is found on a table in a later section of the main story, and its exact location can be found using the Map Genie map.
  • Krellum: This weapon drops when you defeat the chromatic enemy in the Yellow Harvest region. Its Level 10 perk is particularly noted as a strong feature.
  • Best Weapons for Verso

    Verso benefits from weapons that can be integrated into specific builds to maximize their potential.

  • Fragro: Described as one of the 'absolute favorite weapons' in the game, Fragro is considered 'really cool' when built around properly.
  • Corpesso: Obtained by defeating the first group of enemies in the Dark Shores region.
  • General Weapon Tips

    Beyond just finding the best weapons, upgrading them to unlock all their perks and boost their attack power is essential. This requires specific 'chroma catalysts.' However, even more critical than weapons and upgrades are 'pictos' and 'Luminina,' which are considered the most important items for becoming overpowered.
