Dr. Ratio, the enigmatic genius of Honkai: Star Rail, is more than just a quirky character with a fancy name. With the right build and a formidable team, this 5-star main DPS can unleash havoc on the field, leaving a trail of defeated opponents in his wake. Join me as we delve into the secrets of Dr. Ratio's potential and witness the explosive symphony he conducts in battle!
Introduced in Version 1.6, Dr. Ratio utilizes Imaginary DMG and follows the Path of the Hunt. His unique Path makes him a specialist in obliterating individual adversaries rather than spreading his damage thin. Moreover, his Element, Imaginary, makes him a coveted asset due to the scarcity of Imaginary DPS characters in Honkai: Star Rail, with the exception of the elusive Imbibitor Lunae.
Now, if the elusive 5-star Dan Heng is beyond your reach, fear not! Dr. Ratio proves to be a fantastic substitute, especially for those seeking to melt away HP bars with surgical precision. In fact, you can even obtain a free copy of Dr. Ratio until the end of Version 2.1, courtesy of the generous developers at HoYoverse. Once you've Ascended and leveled up our brilliant doctor, it's time to dive into the nitty-gritty of his build, Light Cones, and team compositions—ingredients that will amplify his power to unprecedented heights.
Enter Baptism of Pure Thought, Dr. Ratio's signature 5-star Light Cone. This exquisite piece of equipment, obtainable during limited weapon banner runs, offers a solid base ATK (582 at level 80). However, its true brilliance lies in the Superimposition ability. Equipping this Light Cone grants Dr. Ratio a 20% boost to CRIT DMG. But wait, there's more! With each debuff on a target, Dr. Ratio's CRIT DMG against said target increases by a staggering 8% per debuff, for a maximum of three stacks, resulting in a total of 24% bonus damage.
That's not all! Baptism of Pure Thought also bestows upon Dr. Ratio the Disputation effect when he unleashes his Ultimate, increasing his overall DMG by 26%. As if that weren't enough, this effect allows his subsequent attacks to disregard a whopping 24% of the target's DEF stat. It's a match made in heaven for Dr. Ratio, showcasing the Light Cone's synergy with his kit, amplifying his CRIT DMG and empowering his follow-up attacks—an absolute game-changer.
Of course, not everyone has access to Dr. Ratio's coveted signature weapon. Fear not, for there are viable 5-star alternatives. Take Topaz's weapon, Worrisome Blissful, for instance. With an 18% bonus to CRIT Rate and a 30% boost to follow-up attack DMG, it harmonizes beautifully with Dr. Ratio's playstyle. Moreover, after Dr. Ratio performs a follow-up attack, the target becomes Tamed, stacking up to two times. Each Tame stack increases the CRIT DMG dealt by a delightful 12% whenever the Tamed target is struck by an ally. While originally designed for Topaz, Worrisome Blissful seamlessly integrates into Dr. Ratio's gameplay kit.
Now, let's explore the best build for Dr. Ratio, from Light Cone options to Relics and Ornaments, as well as his Skill Priority. Brace yourself for a symphony of statistics and strategies:

But what if the glistening 5-star Light Cones elude your grasp? Fear not, my resourceful companion! There are viable 4-star alternatives that can still shine brightly in Dr. Ratio's hands. Swordplay and Return to Darkness, two of the finest 4-star Light Cones, offer excellent bonuses to CRIT DMG and CRIT Rate, along with potential buffs to follow-up attacks—a crucial aspect of Dr. Ratio's devastating arsenal.
Now, let's turn our attention to the gear that complements Dr. Ratio's brilliance. The Wastelander of Banditry Desert Relic set takes center stage, granting a 10% bonus to Imaginary DMG with its two-piece bonus. As for its four-piece bonus, Dr. Ratio's attacks on debuffed enemies see a 10% increase in CRIT Rate and a staggering 20% boost in CRIT DMG against Imprisoned enemies. It's a match made in the sandy dunes of Honkai: Star Rail, solidifying Wastelander of Banditry Desert as the go-to Relic set for our calculated doctor.
Moving on to Planar Ornaments, Inert Salsotto steals the spotlight as Dr. Ratio's best choice. While other sets may offerdecent bonuses, Inert Salsotto's unique ability takes the cake. When Dr. Ratio uses an Ultimate, he gains an ATK bonus of 20% for 8 seconds, which stacks up to three times. This bonus greatly enhances his damage output, making it an essential choice for unleashing his explosive symphony.
Now that we have Dr. Ratio's build covered, let's explore team compositions that bring out the best in our esteemed doctor. As a DPS character, Dr. Ratio benefits from supports that can trigger debuffs on enemies. Characters like Imbibitor Lunae and Dan Heng work exceptionally well in tandem with Dr. Ratio, providing debuffs and additional damage amplification.
Imbibitor Lunae, a rarity in the Imaginary department, synergizes perfectly with Dr. Ratio due to their shared Element. Her Elemental Skill and Burst abilities inflict debuffs that increase Dr. Ratio's damage potential. Furthermore, Lunae's Burst ability boosts the team's Elemental DMG by 30% for a considerable duration, further amplifying Dr. Ratio's destructive force.
Dan Heng, the elusive 5-star character, is another exceptional choice for Dr. Ratio's team. Her Elemental Skill and Burst unleash a flurry of damage, inflicting debuffs that increase Dr. Ratio's damage output. Additionally, when Dan Heng performs a follow-up attack, she triggers an AoE explosion that deals massive damage, further bolstering the team's overall damage potential.
To round out the team, support characters like Topaz and Mirai can provide healing and defensive capabilities. Topaz's healing abilities ensure Dr. Ratio's survival, while Mirai's protective shields mitigate incoming damage, allowing the team to focus on dealing devastating blows.
With the right build and a well-crafted team composition, Dr. Ratio proves to be a force to be reckoned with in Honkai: Star Rail. His explosive symphony of damage, amplified by his Light Cone, Relics, and Ornaments, makes him a versatile and fearsome DPS character. So, gear up, assemble your team, and let the calculated chaos unfold as you unleash Dr. Ratio's might upon the battlefield!
