A "Skill Tree" is a visual representation of abilities or skills that a character or player can develop in a game or system. It typically branches out, showing how basic skills can lead to more advanced ones. Players can choose which skills to unlock, allowing for personalized gameplay and strategies. Skill trees are commonly found in role-playing games (RPGs) and video games, where they enhance character development. They can also be used in educational contexts, helping learners track their progress in acquiring new skills. Overall, skill trees provide a structured way to visualize growth and choices in skill acquisition.
