This sound comes from The Elder Scrolls V: Skyrim, released by Bethesda in 2011. In the game, players hear it when a skill increases, which made it one of the most recognizable interface sounds in modern RPGs. As Skyrim became a long-running meme and modding staple, the level-up cue spread into YouTube edits, Twitch moments and short-form videos. It still gets used because the sound communicates instant progress and reward in less than a second, even to people who have only seen Skyrim clips online.
