Skills in Fire Emblem: Three Houses cover the aspects of combat in the game. As a professor, Byleth can tutor their students in these skills, thus increasing their effectiveness in combat. As characters improve their skills, they will learn abilities, combat arts, and be able to use more advanced weapons. Continuing on the schooling theme, units must achieve enough experience in certain skills to be able to take class certification exams. As the player improves their own skills, they will gain respect from other students, allowing them to be recruited.
