Here's why it's considered rising action:
* Raises the Stakes: Mal's plan to use the wand to control Auradon and bring her mother back to the Isle of the Lost significantly raises the stakes for the entire story. It creates a tangible threat to the peace and order of Auradon, and directly challenges the authority of King Beast and Queen Belle.
* Escalates Conflict: Mal's choice to steal the wand increases the tension between the VKs and the Auradon residents. It makes them all feel threatened and forces them to take action.
* Triggers Reactions: This action prompts King Beast to call for the coronation of Ben, pushing the plot forward and setting the stage for the next major event – the arrival of the VKs on Auradon.
This event, therefore, acts as a significant turning point in the story, propelling the plot forward and creating the momentum necessary for the climax of the film.
