Dr. Ratio is a 5-star Imaginary Single-Target DPS (The Hunt) in Honkai: Star Rail. Dr. Ratio is a free 5-star Imaginary DPS who turns enemy debuffs into damage multipliers. His kit revolves around automatically triggering follow-up attacks whenever enemies are sufficiently debuffed, making him a carry who gets stronger the more your supports do their job. He rewards debuff-stacking team compositions and punishes passive, uncoordinated lineups. In dedicated debuffer teams, his damage scales aggressively — each additional debuff on a target directly amplifies what he deals.
