What is the building action of a story?

The building action of a story is the part where the plot thickens and the conflict begins to escalate. This is typically the middle of the story, after the inciting incident has occurred and the protagonist has set out on their journey.

During the building action, the protagonist faces a series of challenges and obstacles that make it increasingly difficult for them to achieve their goal. The conflict intensifies, and the stakes get higher. This part of the story is often filled with suspense and danger, as the protagonist struggles to overcome the forces that are arrayed against them.

The building action typically culminates in a climax, which is the highest point of tension in the story.
