To unleash the full potential of Dr. Ratio, gamers need to use Light Cones which can improve their in-game effectiveness. Below, we’ve listed the five best light cones for Dr. Ratio in Honkai: Star Rail.

#1: Baptism of Pure Thought

  • Effect: Increase CRIT DMG by 20%/23%/26%/29%/32%. For every debuff on the enemy, CRIT DMG increases further by 6%/7%/8%/9%/10%, with a maximum of 3 stacks. When using the Ultimate, your character receives the Disputation effect for 2 turns. This increases DMG by 36%/42%/48%/54%/60% and makes follow-up attacks ignore 20%/23%/26%/29%/32% of the enemy’s defense.

Being featured in Dr. Ratio’s banner, Baptism of Pure Thought is the best option for this character, while also being useful for various other characters. Baptism of Pure Thought significantly increases CRIT DMG, which makes it helpful for teams focused on debuffing enemies.

It’s worth noting that Baptism of Pure Thought is not a must for Dr. Ratio. Gamers can save resources and choose more affordable options listed below.

#2: Worrisome, Blissful

  • Effect: Increase CRIT Rate by 18%/21%/24%/27%/30%, while also increasing DMG from follow-up attacks by 30%/35%/40%/45%/50%. When a follow-up attack is used, apply the Tame state to the target (when allies hit enemies under the Tame state, every stack will increase incoming CRIT DMG by 12%/14%/16%/18%/20%).

While ‘Worrisome, Blissful’ is not the featured light cone of Dr. Ratio, it was designed for Topaz, another powerful character who benefits from follow-up abilities. ‘Worrisome, Blissful’ increases CRIT Rate and DMG from follow-up attacks, making it the perfect option for Dr. Ratio DPS builds.

#3: Sleep Like the Dead

  • Effect: Increase CRIT DMG by 32%/40%/48%/56%/64%. When a basic attack or skill doesn’t complete a CRIT Hit, it increases the CRIT Rate by 40%/45%/50%/55%/60% (only for one turn). This effect can be applied only once every 3 turns.  

Sleep Like the Dead might not be the most obvious choice for Dr. Ratio, but it can offer significant benefits to the character. 

Sleep Like the Dead significantly increases CRIT DMG, which synergizes well with Dr. Ratio’s focus on exploiting debuffs to increase his CRIT Rate and damage. This yields benefits for both DPS and sub-DPS builds.

Why did we put Sleep Like the Dead in third place? The bonus effect of this light cone relies on circumstances that players can’t control. Therefore, Worrisome, Blissful, and Baptism of Pure Thought will be way more powerful in the long run.

#4: Cruising in the Stellar Sea

  • Effect: Increase CRIT Rate by 8%/10%/12%/14%/16%. If the enemy’s HP is less than or equal to 50%, the CRIT Rate increases by an additional 8%/10%/12%/14%/16%. Once the character defeats an enemy, it increases DMG by 20%/25%/30%/35%/40% (only for 3 turns).

Cruising in the Stellar Sea has a powerful passive effect with a solid stat boost in CRIT Rate. Beyond its impressive 16% CRIT rate boost, its true strength lies in its straightforward benefits – a consistent activation mechanism and reliable damage boost in every game. 

Unlike other Light Cones that rely on specific situations, Cruising in the Stellar Sea applies DMG and CRIT Rate boost in every game.

Gamers can get Cruising in the Stellar Sea from the Herta’s Store in the Simulated Universe, making it one of Dr. Ratio’s best free-to-play light cones.

#5: Swordplay

  • Effect: Increases DMG by 8%/10%12%/14%/16% each time you hit the same target stacking up to 5 times. When the wearer changes targets, the stack effect will be reset.

Swordplay is the light cone I love to use, although sometimes it feels inconsistent. Swordplay significantly increases DMG dealt by follow-up attacks.

This effect can stack up effectively even within the same turn, which might be very helpful during battles against bosses or formidable enemies.

However, during battles against crowds of enemies that die from multiple hits, Swordplay’s effect is impossible to reach, making this light cone useless.
