This sound is associated with the Heal Spell in Clash of Clans, the mobile strategy game released by Supercell in 2012. Players recognize it from battles where the spell restores troops inside its area. Outside the game, the clip spread through gaming memes, short edits and soundboards because it instantly communicates recovery or support. It still gets used when a video needs a quick audio shorthand for healing, buffing or rescuing a situation, especially in game-related posts and comeback jokes.
