Cursed sword

Cursed and legendary swords appear across mythology, history, literature, and gaming. Blades like the Norse Tyrfing, Ainu ipetam, and Japanese Muramasa katanas are famously depicted as bloodthirsty items bringing inevitable tragedy. Psychologically, the belief in curses stems from confirmation bias and the nocebo effect. Today, cursed items serve as compelling narrative tools, forcing characters to weigh immense power against devastating costs.
