The phrase “On the case” is not an official game mechanic, ability, or feature in League of Legends. Instead, it is most often a direct reference to a voice line used by certain champions, particularly those with a detective or law enforcement theme, or it may be used in the context of temporary in-game event missions.
Because the term has no defined gameplay function, its meaning always relies on the context of the game’s lore, voice acting, or temporary event content.
1. Champion Voice Lines: The Detective Persona
The most common source of the phrase is the in-game audio of champions. The line “On the case!” fits perfectly with champions whose persona is built around investigation, policing, or vigilantism.
- Caitlyn, the Sheriff of Piltover, is the champion most closely associated with the phrase. Her primary theme is that of a top-tier investigator, and lines like this are used when she moves, attacks, or uses certain abilities to reinforce her role as Piltover’s premier law enforcement officer.
- The phrase can also be found in the voice sets of skins or champions that adopt a similar sleuthing or agent aesthetic, often used as a playful catchphrase to humorously reinforce their investigative vibe.
2. Event Missions and Themed Content
Riot Games frequently runs limited-time events, which often include specific mission objectives. In events with a crime, law, or investigation motif—especially those tied to the lore of Piltover or Zaun—mission titles or objectives might adopt playful names like:
- “On the Case”
- “Close the Book”
- “Find the Clue”
These themed quests challenge players to achieve specific in-game milestones (like getting a certain number of kills or placing wards) to earn event rewards, but the title itself does not describe a core, permanent game mechanic.
3. Community and Fan Culture
Finally, the term is used informally within the League of Legends community. Players may reference it in memes, fan art, or during social media discussions when roleplaying or talking about their favorite “detective” champions, creating an unofficial piece of the game’s cultural slang.
