Best ways to farm Relics in Honkai: Star Rail

One of the best parts about Honkai: Star Rail is there are so many characters for you to unlock, either through the story or from warping. As you’re leveling them and working on finding the best Light Cones, you must also equip your characters with the best Relics.

Relics are essential items that can help increase your character’s stats and enhance abilities. So, how do you get Relics in Honkai: Star Rail?

Honkai: Star Rail: How to get Relics

Relics are essential items you’ll need to farm for in Honkai: Star Rail. There are six different types you must equip your character with, including Head, Hands, Body, Feet, Planar Sphere, and Link Ropes.

It’s important to note not all Relics are suited for every character, meaning they may not offer beneficial or suitable stats or effects for one character, but they might be the best for another. 

In Honkai: Star Rail, there are two main ways to get Relics: Caverns of Corrosion or Immersion Rewards in the Simulated Universe. And you can view both of these under the Survival Index tab in the Interastral Guide.

So, here’s everything you need to know about the Caverns of Corrosion, where they’re located, and Immersion Rewards in the Simulated Universe. 

Honkai: Star Rail: Cavern of Corrosion 

The Caverns of Corrosion are located across all the Navigation points on the Star Rail Map, meaning you’ll find them on the Herta Space Station, Jarilo-VI, and The Xianzhou Loufu. They’re initially unlocked at level 24 after you complete the The Stars Are Cold Toys mission.

As you raise your Trailblazer and Equilibrium levels, you’ll unlock new areas and Caverns of Corrosion. And you’ll unlock new difficulty levels of the caverns. For every cavern run-through, it will cost you 40 Trailblaze Power. You can complete four cavern runs with a full 180 Trailblaze Power bar, giving you a relatively decent number of Relics.

What types of Relics can I get from the Cavern of Corrosion?

In the Caverns of Corrosion, you’ll battle different enemies for a chance to get certain Relics and rewards like Trailblazer EXP. Each cavern offers different types of Relics, so you may need to run through several caverns to farm for Relics for all your characters.

Regarding Relics, the only ones you can get from the Caverns of Corrosion include: 

• Head
• Hands
• Body
• Feet 

The other two Relics can only be obtained through Immersion Rewards in the Simulated Universe.

You can obtain items from two Relic sets in each cavern, each with stats and bonus effects, depending on how many pieces your character is wearing. 

What’s the star rating, or rarity, of the Relics I may get from a Cavern of Corrosion?

Each Cavern of Corrosion offers six difficulty levels, and you may encounter different enemies with each level. And there are also various Relics for you to get. 

The star rating or rarity of your Relic depends on the cavern’s difficulty levels, which include:

• Difficulty One: May get Relics between two and four stars
• Difficulty Two: Unlocks at Equilibrium level two: May get Relics between two and four stars
• Difficulty Three: Unlocks at Equilibrium level three: May get Relics between three and five stars
• Difficulty Four: Unlocks at Equilibrium level four: May get Relics between three and five stars
• Difficulty Five: Unlocks at Equilibrium level five: May get Relics between three and five stars
• Difficulty Six: Unlocks at Equilibrium level six: May get Relics between four and five stars

Although you may be able to get five-star Relics from Difficulty Three caverns, this is not guaranteed. So, save your Fuel until you unlock the sixth difficulty, where your chances of getting five-star Relics are much higher. 

But, if you’re ready to start farming for Relics, here are all the Cavern of Corrosion locations and what Relics you may obtain.
