Which element is most important for a successful character arc?

A successful character arc is fundamentally driven by the internal conflicts faced by the character. This internal struggle is what propels the character’s development and transformation over the course of the narrative. It often presents the character with challenges that force them to evolve, make important decisions, and ultimately relate to their desires and fears in a meaningful way. The resolution of these internal conflicts typically signifies the completion of the character arc, showcasing how the character has grown or changed as a result of their experiences.

While other elements, such as dialogue, interactions with minor characters, and the setting, contribute to the overall narrative and can enhance the characterization, they serve as frameworks or contexts within which the internal conflicts unfold. The essence of a character arc lies in the emotional and psychological journey of the character, making the internal conflicts central to the narrative's impact.
