Lost Age World

"In this world, people possess four skills tied to their equipment: 'weapon skill,' 'helmet skill,' 'armor skill,' and 'trinket skill.' However, they can only freely swap three of them—helmet, armor, and trinket—while the 'weapon skill' remains permanent. This is because a person’s weapon is also called their 'birth weapon,' as it appears alongside them when they are born. Tournaments are the main event in this chaotic world where all kinds of fantasy races from the past, present, and future emerge, and even technology from past, present, and future appears, Our story follows a man from another world who suddenly finds himself reincarnated inside it. Strangely, this world was once just a game he used to play—but now, it’s his reality."
