Are all the Dr. Ratio’s Eidolons in Honkai Star Rail worth an investment?

For the free-to-play players, Dr. Ratio's base kit is already perfect. However, some Eidolons like E1 and E2 give low-cost power spikes. They elevate Dr. Ratio’s consistency. The instant CRIT stacks of E1 make the relic-building less punishing. As for E2, it turns the follow-up attacks to the debuff-fuelled nukes. It is ideal for a team with characters like Pela or Silver Wolf.


The high-tier Eidolons E4 and E6 cater to the dedicated mains or whales. The damage boost of E6 is quite substantial. However, the cost to reach it might not justify the payoff compared to pulling some other meta units. So,

• Give priority to E1-E2 for efficiency.
  
• Mid-tier choices like E2 offer some solid damage scaling. But until the aim is for the full build, saving the resources for the other characters will be a smart move.
  
• Consider E6 if Dr. Ratio is the main carry. It is powerful and demands some excessive pulls.
  
• Pairing Dr. Ratio with the debuffs will maximize his Eidolon perks. It will make him the versatile choice for the endgame content.
  

In the game where resource management is key, the Eidolons of Dr. Ratio offer some flexible upgrades. Whether you as a player are chasing the CRIT consistency or the Ultimate uptime, the toolkit adapts to the competitive and casual playstyles. Choose wisely.
