Topaz is a Fire Element Follow-up DPS character in Honkai: Star Rail who serves as a genius moneylender and debt collector. She is a great support character for Follow-up attack teams, capable of dealing significant single-target damage and increasing the entire party's Follow-up Attack damage. Her Skill Point efficiency and ability to deal substantial Toughness damage when her Ultimate is active make her a valuable sub-DPS. While her personal damage output isn't exceptional on its own, she excels when paired with other Follow-up attack-focused characters like Himeko and Jing Yuan, helping them break enemy weaknesses and trigger their Follow-up attacks more frequently. She is known for her mysterious and bold nature, approaching situations with a pragmatic mindset focused on profit and advantage.
