Dr. Ratio is one of the characters from Honkai: Star Rail, with exceptional prowess when it comes to inflicting damage on a single target. His formidable subsequent strikes prove to be highly effective, especially against Bosses, and their potency increases significantly when targets are under debuffs. If you require a formidable annihilator with a specialization in follow-up attacks, Dr. Ratio is definitely worth investing in.
