Dr. Ratio is a 5-star character from the Path of the Hunt that many of us were able to obtain entirely for free, thanks to the numerous accolades Honkai Star Rail received during its first year of release.
Regarding the character itself, he is genuinely intriguing and somewhat atypical compared to other characters on the Path of the Hunt. However, he is, of course, oriented towards Single Target damage, as is common in his path.
Dr. Ratio reaps significant benefits when attacking enemies afflicted with debuffs (beyond the advantages provided by the debuff effects themselves). Therefore, he is a character often paired with at least one Nihility Path character, as you'll see further below in the Best Teams section.
He excels at dealing substantial damage to Single Targets, and his primary source of damage (though not to discount his effectiveness from other sources) comes from Follow-up Attacks. Moreover, depending on the number of debuffs on enemies, it becomes more likely for this character to activate them more frequently.
Base Stats
Dr. Ratio DPS
A fairly standard DPS build. The key consideration is that Dr. Ratio deals significant damage with his Follow-up Attacks and greatly benefits from being accompanied by characters from the Nihility Path.
