The act of repeatedly encountering Pokmon in the game Pokmon Sword with the specific intent of finding a rare, differently colored (shiny) version is a pursuit known as shiny hunting. It is a method employed by players seeking to obtain aesthetically unique Pokmon that possess the same stats and abilities as their normally colored counterparts. For example, a trainer might repeatedly battle or breed Charmander until a shiny Charmander appears.
This practice provides a long-term goal for many players after completing the main storyline and completing their Pokdex. Shiny Pokmon are visually distinctive and serve as trophies, symbolizing dedication and effort invested in the game. Historically, the odds of encountering a shiny Pokmon have been relatively low, making the acquisition of one a significant achievement within the player community. These odds can be altered by specific items and strategies explained later.
