Heartsteel was added to League of Legends for the 2023 preseason as a health-focused tank item built around stacking. Its Colossal Consumption passive marks nearby enemies, and a charged attack consumes the mark for bonus damage and permanent maximum health. That simple loop made it a favourite for champions like Sion and Cho'Gath, and clips of endless stacking started spreading on YouTube and TikTok. The distinctive proc noise became shorthand online for getting impossibly tanky, separate from normal League sound effects.
