Honkai: Star Rail – Dr. Ratio build and ascension guide

by

Transform into an unbearably meme-tastic mastermind by perfecting the optimal Honkai: Star Rail Dr. Ratio setup, and silence all skeptics by demonstrating your dominance, as this 5-Star character, treading The Hunt’s path, amplifies your arsenal with Imaginary Damage, pushing any Follow-Up Attack team to their limits.

Dr. Ratio’s skill, Intellectual Midwifery, inflicts imaginary damage on a single opponent. His talent, Cogito, Ergo Sum, offers him a constant 40% opportunity to execute a follow-up attack after using his skill, targeting the same opponent and causing more imaginary damage. These abilities are tied to his attack power. Each debuff applied to the target raises the probability of a follow-up attack by 20%.

In simpler terms, “His final move, the Syllogistic Paradox, inflicts imaginary damage proportional to his attack power on a single opponent and triggers Wiseman’s Folly. If any of Dr. Ratio’s allies assault an enemy under Wiseman’s Folly’s influence, he will retaliate with a Follow-Up Attack against that target. This response can be activated twice, but it only affects the most recent enemy hit by his ultimate move.

Obtaining extra versions of Dr. Ratio raises his power significantly. At Eidolon Level 1, he can accumulate more buffs from Summation Trace. With Eidolon Level 2, each debuff on the target amplifies his Follow-Up Attack’s damage. At Eidolon Level 4, using his talent restores energy for Dr. Ratio. Eidolon Level 6 allows Wiseman’s Folly to be triggered one more time. Furthermore, his Follow-Up Attack becomes much stronger, dealing an impressive 50% more damage.

Honkai: Star Rail – Dr. Ratio: best teams

To maximize the capabilities of Dr. Ratio, it’s essential to introduce a character capable of weakening enemies, thereby allowing the damage-dealing character to frequently execute Sequential Assaults.

  • Dr. Ratio (Main DPS), Topaz (Sub DPS), Robin (Support), Aventurine (Support)

Dr. Ratio significantly gains an advantage with Topaz, not just causing a debilitating status on opponents that weakens them, but also enhancing subsequent attacks against the afflicted target – a double benefit for the doctor. Furthermore, the offensive enhancements provided by Robin and the consistent defense of Aventurine contribute to making this team one of the strongest in the entire game.

  • Credits x308,000
  • Thief’s Instinct x15
  • Usurper’s Scheme x15
  • Conqueror’s Will x15
  • Suppressing Edict x65

As a gamer, I can tell you that I can grab Thief’s Instinct, Usurper’s Scheme, and Conqueror’s Will from Antimatter Legion foes on Herta Space Station and the Simulated Universe. I can also craft or swap these items using the Omni-Synthesizer on the Astral Express. Thief’s Instinct is a basic material that I can efficiently farm through Daily Assignments to my characters, providing a consistent supply of the resource. Suppressing Edicts, on the other hand, are either dropped by the Stagnant Shadow (Artisanship Commission) or obtained via trading similar scarce materials. The primary source of Credits is the Golden Calyxes found on numerous planets.

Dr. Ratio requires the following materials to upgrade her combat abilities and Traces:

  • Credits x3,000,000
  • Thief’s Instinct x41
  • Usurper’s Scheme x56
  • Conqueror’s Will x58
  • Arrow of the Beast Hunter x18
  • Arrow of the Demon Slayer x69
  • Arrow of the Starchaser x139
  • Past Evils of the Borehole Planet Disaster x12
  • Tracks of Destiny x8

To review the previously mentioned items, please look upwards. You’ll find Arrows being cultivated in the Crimson Calyx, located within the Outlying Snow Plains. As always, you can synthesize advanced materials by processing lower-level ones inside the Omni-Synthesizer on board the Astral Express.

In simpler terms, you can acquire the “Boss Material from the Borehole Planet Catastrophe” exclusively in the “Echo of War (Seclusion Zone)” domain. On the other hand, “Tracks of Destiny” can be obtained during special events like time-limited events, “The Embers Exchange”, “The Nameless Honor”, or as a reward for earning points in a Simulated Universe.
