Introductions
Welcome to our team composition guide for Dr. Ratio in Honkai: Star Rail. In this guide, we'll explore the best teams to build for Dr. Ratio, including recommended team compositions, character synergies, and everything you need to know.
Best Synergies for Dr. Ratio
Silver Wolf provides plenty of debuffs to consistently trigger Dr. Ratio's Follow-Up ATKs while maximising his debuff-based damage bonuses.
Topaz and Numby provide key debuffs for Dr. Ratio while enhancing Follow-Up ATK teams. Topaz's E1 or Light Cone means she can meet 2 of his debuff requirements therefore he will need 1 other source for example from another allies skill. Dr. Ratio's frequent Follow-Up ATKs also help advance Numby's actions for improved team damage.
Jiaoqiu provides multiple consistent debuffs, helping Dr. Ratio reliably meet his debuff requirements, making it easier to maximise Dr. Ratio's damage.
Aventurine can apply a CRIT DMG Vulnerability debuff, and when his signature Light Cone is equipped, it provides an additional debuff, further supporting Dr. Ratio.
Robin increases all allies' DMG by 50% for 3 turns and provides allies with immediate action advancement alongside an ATK increase upon using her Ultimate. Her Talent further increases all allies' CRIT DMG while regenerating Energy for herself, making her a solid amplifier for Dr. Ratio and the entire team.
