Become an insufferable lord of memes with the best Honkai: Star Rail Dr. Ratio build and show all of your detrimentors the L – and do all of it for free. Anyone playing between version 1.6 and 2.1 is able to claim a free Dr. Ratio, adding the 5-Star character following the Path of The Hunt and dealing Imaginary Damage to their arsenal.

Dr. Ratio’s Skill, Intellectual Midwifery, deals Imaginary Damage to a single target. His Talent, Cogito, Ergo Sum, gives him a fixed 40% chance to launch a follow-up attack after using his Skill, against the same target dealing Imaginary Damage. Both are based on his Attack stat. Each debuff on the target increases the chance to launch a follow-up attack by 20%.

His Ultimate, Syllogistic Paradox, deals Imaginary Damage based on his Attack to a single target and applies Wiseman’s Folly. If Dr. Ratio’s allies attack an enemy affected by Wiseman’s Folly, he’ll use his follow-up attack against this target. This can be triggered two times and only affects the latest enemy to be hit by his Ultimate.

Dr. Ratio’s Eidolon Levels, which are obtained by pulling additional copies of him, further boost his effectiveness. Eidolon 1 allows him to stack additional buffs from his Summation Trace and Eidolon 2 enables his follow-up attack to deal additional damage for each debuff on the target. Eidolon 4 regenerates Energy for Dr. Ratio when his Talent is used. Finally, Eidolon 6 increases the amount of times Wiseman’s Folly can be triggered by one. In addition, his follow-up attack’s damage is increased by a staggering 50%.

Honkai: Star Rail – Dr. Ratio: best Light Cones

Dr. Ratio has a signature Light Cone, which is called Baptism of Pure Thought and provides a powerful boost to Critical Hit Rate. In addition, it increases the wearer’s Critical Hit Damage for every debuff on the enemy target, stacking up to three times. When using their Ultimate, the wielder receives the Disputation effect for two turns, which increases the overall damage dealt by them as well as allowing their follow-up attacks to partially ignore the enemy’s Defense.

This is a beastly offensive Light Cone that perfectly complements Ratio’s playstyle.

• Baptism of Pure Thought (5-Star)
• Worrisome, Blissful (5-Star)
• Cruising in the Stellar Sea (5-Star)

Honkai: Star Rail – Dr. Ratio: best teams

Using Dr. Ratio to his full effect requires you to bring a character that can debuff the enemy, which will enable the damage dealer to consistently unleash follow-up attacks.

• Dr. Ratio (Main DPS), Silver Wolf (Support), Yukong (Support), Huohuo (Support)

Silver Wolf can easily inflict debuffs on enemies, allowing Dr. Ratio to take them out with his follow-up attacks. Yukong is a strong support for Imaginary Damage characters, tuning those critical stats even higher. Fill the sustain slot with whomever you have available, as usual.

Pela is another fantastic debuffer you should keep in mind for Dr. Ratio, while the usual cast of supports like Bronya, Tingyun, Asta or Ruan Mei are all strong with the intellectual as well. If you have Topaz at Eidolon 1, she can be considered a potent support for Dr. Ratio as well.
