Dr. Ratio is one of Honkai: Star Rail’s most unique units for several reasons. He has an incredible name and is a premium five-star you can get for free. Dr. Ratio is also still like other characters in that you have to farm lots of important materials for him.

Even if you don’t plan on using Dr. Ratio as one of your main playable units, he’s such a strong damage dealer that it’s a good idea to build him regardless so you can deploy him whenever you need to. Here are all of the materials you need to build Dr. Ratio in Honkai: Star Rail.

All Dr. Ratio materials in Honkai: Star Rail

The highly intelligent Dr. Ratio requires a wide variety of resources including Ascension materials and Trace materials. There is some overlap in the items he needs for both, so you’ll need to farm for some resources much more than others.

Dr. Ratio Ascension materials in Honkai: Star Rail

To fully Ascend Dr. Ratio, all of the Ascension materials you need are:

  • 308,000 Credits
  • 15 Thief’s Instinct
  • 15 Usurper’s Scheme
  • 15 Conqueror’s Will
  • 65 Suppressing Edict

Dr. Ratio Trace materials in Honkai: Star Rail

Across all of Dr. Ratio’s Traces, you need to gather all of the following Trace materials.

  • 3,000,000 Credits
  • 18 Arrow of the Beast Hunter
  • 69 Arrow of the Demon Slayer
  • 139 Arrow of the Starchaser
  • 41 Thief’s Instinct
  • 56 Usurper’s Scheme
  • 58 Conqueror’s Will
  • 12 Past Evils of the Borehole Planet Disaster
  • Eight Tracks of Destiny

This might seem like a lot of resources, but you don’t need all of them at once. Instead, you’ll be breaking down the total Trace materials across each specific Trace, which makes the farming process a lot more doable.

To level up one individual Trace to level 10, Dr. Ratio needs:

  • 652,000 Credits
  • Three Arrow of the Beast Hunter
  • 15 Arrow of the Demon Slayer
  • 30 Arrow of the Starchaser
  • Nine Thief’s Instinct
  • 13 Usurper’s Scheme
  • Seven Conqueror’s Will
  • Three Past Evils of the Borehole Planet Disaster
  • Two Tracks of Destiny

The five-star Imaginary Hunt recruit is one of Honkai: Star Rail’s best characters yet and you can obtain him for free, so you certainly want to work hard on providing him with a strong build. Obtaining the right materials for him is only the first step as you also need to ensure he has strong Relics, a powerful Light Cone, and a stellar team lineup.
