Honkai: Star Rail - Dr. Ratio Character Ascension (& Materials)

Farming materials for Dr. Ratio’s character Ascension in can be a long and tiresome process, but it is extremely valuable in case you want to take the 5-star character to his limits in combat. Dr. Ratio is a 5-star that uses Imaginary Damage and follows the Path of the Hunt. His choice of Path makes him a DPS unit in the turn-based RPG by HoYoverse. Due to his element and Path, this character is great to have around, and luckily, you can get a free Dr. Ratio in until the end of Version 2.1.

After that, you will have to rely on his limited-time banner coming into rotation to obtain Dr. Ratio. This character specializes in dealing a high amount of single-target damage, making him lethal. Before getting to this stage, however, you will have to farm and muster up the required materials to level him up to 80, going through the several stages of character Ascension that often act as thresholds. These Ascension levels will impede you from further leveling him, so it is important to have Dr. Ratio’s materials in at hand and ready for use.

The first set of materials you will need to farm for Dr. Ratio is Thief’s Instinct and its evolved forms, Usurper’s Scheme and Conqueror’s Will, respectively. These items drop from regular Antimatter Legion units, including Baryon, Antibaryon, Voidranger: Distorter, Voidranger: Eliminator, and Voidranger: Reaver. Good locations to farm Thief’s Instinct, Usurper’s Scheme, and Conqueror’s Will are the Storage Zone and the Supply Zone in Herta Space Station. Logically, these items can also be obtained from the enemies when fought in the Simulated Universe in. You can also purchase some through Embers Exchange or obtain them from Assignments.

You will need to farm a surplus of Thief’s Instinct, Usurper’s Scheme, and Conqueror’s Will, as they are also needed for leveling Dr. Ratio’s Traces and unlocking his new abilities.

As Ascension levels go by, you will stop Dr. Ratio needing Thief’s Instinct and start requiring Usurper’s Scheme. Similarly,
