Dr. Ratio

Dr. Ratio is a playable character in the game Honkai: Star Rail, affiliated with the Intelligentsia Guild. He is known for his candid and self-assured personality, often concealing his face with a peculiar plaster sculpture. Despite displaying exceptional intelligence and talent from a young age, he now refers to himself as a "Mundanite." He firmly believes that intellect and creativity are not exclusive to geniuses and seeks to distribute knowledge throughout the universe to cure the persistent ailment of ignorance. As an Imaginary-type character following the Hunt Path, Dr. Ratio excels in single-target damage output. His abilities are heavily reliant on the number of debuffs on enemies, with more debuffs increasing his chances of launching additional attacks. His skills include normal attacks, skills, ultimates, and talents, as well as a unique technique that inflicts a speed debuff on all enemies at the start of battle. His additional attack mechanics make him most effective when paired with characters that can apply debuffs. In the game, he possesses a unique character story and background, and was given as a free limited-time five-star character to players in Version 1.6.
