Our Honkai Star Rail Dr Ratio materials list lays out what you need for each ascension milestone and everything you need for his most important Traces. If you're wondering what he actually does in battle, check out our Dr Ratio kit and Traces priority guide and Dr Ratio build.

Dr Ratio materials for ascension

Here’s what you need get Dr Ratio from level one to 80.

Level Dr Ratio ascension materials Cost in Credits
20 5 Thief's Instinct 4,000
30 10 Thief's Instinct 8,000
40 6 Usurper's Scheme, 3 Suppressing Edict 16,000
50 9 Usurper's Scheme, 7 Suppressing Edict 40,000
60 6 Conqueror's Will, 20 Suppressing Edict 80,000
70 9 Conqueror's Will, 35 Suppressing Edict 160,000

How to get Thief's Instinct items

Thief's Instinct items come from Antimatter Legion enemies on Herta's space station, specifically the Voidranger foes and Baryon enemies. You'll find them pretty much everywhere on the Space Station and in most stages of Herta's Simulated Universe.

However, the easiest way to get Instinct, Scheme, and Will items is by sending characters out on daily assignments. If you set the length to the maximum and pick two suitable characters, you'll end up with a couple dozen or so each day.

Where to find Supressing Edict

Supressing Edict comes from the Shape of Puppetry Stagnant Shadow fight. This fight is in the Artisan Commission and features the Aurumaton Gatekeeper as your main foe. So far, Imbibitor Lunae is the only other character who uses these Edict items.

The easiest way to get credits is from one of Golden Calyx. Bear in mind that these cost fuel, so you'll need to balance these challenges with your other level-up activities.

Dr Ratio materials total - Ascension

This is what all that looks like together.

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

Dr Ratio materials for Traces

Dr Ratio uses more Thief's Instinct items for his Traces, along with the usual Hunt items in the Arrow family.

For one Trace that isn't Dr Ratio's basic attack, you need:

  • 9 Thief's Instinct
  • 13 Usurper's Scheme
  • 7 Conqueror's Will
  • 3 Arrow of the Beast Hunter
  • 15 Arrow of the Demon Hunter
  • 30 Arrow of the Starchaser
  • 2 Tracks of Destiny
  • 3 Past Evils of the Borehole Planet Disaster
  • 652,000 Credits

How to get Arrow of the Beast Hunter

The Arrow items come from the Bud of the Hunt Crimson Calyx. You can challenge these as many times as you want, though clearing one wave costs 10 Trailblaze energy. Star Rail is a bit stingy with dishing out fuel, so make sure to plan carefully when deciding who you want to grind materials for.

How to get Past Evils of the Borehole Planet Disaster

The only way to get Past Evils of the Borehole Planet Disaster is by completing the associated Echo of War challenge. It unlocks in the version 1.6 storyline involving Ruan Mei and Dr Ratio, so if you're reading this ahead of that update, you can't farm it beforehand. Unlike other ascension materials, you can't use the Synthesizer to exchange other drops for Borehole Disaster. If you're just getting started, it'll be awhile before you can access it.

Star Rail rewards you with Tracks of Destiny in the battle pass, through completing Trailblaze missions, and for taking part in events.

Dr Ratio Traces materials total

To level up all of Dr Ratio's Traces and unlock every bonus ability, you need:

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

Bear in mind that these are just for Dr Ratio's talent, skill, and ultimate. You'll need additional items for his three major bonus abilities. That's a lot of materials, and since other Hunt characters share many of them, you'll want to plan ahead before deciding what to uppgrade first.
