The Ultimate Boon is the final stage of the initiation process. This stage is when the hero gains limitless bounty or indestructible life. The hero attains enlightenment after facing their fears. It’s the point where everything gets resolved. Here, the hero achieves their goal and is reborn as a higher being. There will be an ultimate boon in my story.
