Clair Obscur: Expedition 33 features an array of characters, each with distinct mechanics, but Gustave stands out as the first playable character. This allows players to familiarize themselves with the gameplay mechanics quickly while also offering the flexibility to customize Gustave’s build, which lies at the heart of the game’s enjoyment.
For instance, players can choose a build for Lune that inflicts significant Burn damage over time, rendering her formidable in battle. Alternatively, they can focus on an Area of Effect (AoE) build that enables her to deal impressive AoE damage each turn.

Strategy for Gustave’s Early Game Build

As the initial character available in Expedition 33, Gustave has a straightforward play style. Players should focus on charging his stack to its maximum before launching attacks. Delay using Gustave’s special attack and rely on his Base Attacks to accumulate the necessary 10 charges. To enhance damage output, it’s crucial to maximize his Luck and Defense to achieve approximately 30% Critical Chance. When paired with Lumina, Gustave could see his Critical Chance rise to 60-70%, contributing to more frequent charges.





As Gustave’s special attack is resource-intensive, especially in the early game, it’s prudent to prioritize Basic Attacks until his AP builds up. While Gustave’s powerful attack alternative is viable, the required AP for it may hinder performance early on. Instead, consider strategies using Basic Attacks to facilitate charging his more potent abilities.



Beyond his offensive capabilities, Gustave’s sustain skills are vital for keeping him alive during battles. Skills that offer healing and debuffs add depth to his gameplay, making him a versatile character. Expanding Gustave’s arsenal to include high AoE damage attacks can significantly enhance team performance during encounters.



The Best NG+ Build for Gustave

Even in New Game Plus, Gustave’s weapons lack inherent effects, which can impact his combat effectiveness. Thus, selecting weapons that align with his preferred attributes is crucial. However, Gustave retains utility through interesting builds centered around support and debuffing.

Strategy for Gustave’s NG+ Build

In his NG+ phase, Gustave’s weapon impacts are minimal, and his skill set is limited, prompting a shift toward a support role in E33. Gustave can effectively apply buffs to his teammates for up to 3 turns, making it advantageous to integrate Luminas that facilitate Rush and Shell applications. This combination amplifies overall team effectiveness significantly.



Once Gustave’s buffing abilities are maximized, consider transitioning him into a debuffer by adding hits to his Base Attacks alongside debuff effects such as Slow, Defenseless, and Powerless. Furthermore, sacrificing some damage output can allow for additional breaking capabilities, providing crowd control (CC) to Gustave’s overall build in Expedition 33.
