First Blood has been a core League of Legends callout since the game launched in 2009, announcing the first champion kill in a match. Riot Games built the game around short, dramatic announcer lines that tell players when momentum shifts, and this one became shorthand for an early lead. As League grew into one of the world's most played games, clips and streams carried the sound beyond matches themselves, and editors now reuse it to frame any opening victory, comeback or competitive moment.
