Honkai Star Rail Cavern of Corrosion Guide: All Locations, Team Comps, and more!

Want to dive inside?

As you progress your account in Honkai: Star Rail, you'll unlock Relics for your characters, the equivalent of Artifacts from Genshin Impact. Here again you'll be facing challenges and spending Trailblaze Power to beat RNG and obtain the best ones to beef up your characters. Not sure where to start? We can help. Here's a complete guide to Caverns of Corrosion in Honkai: Star Rail.

All Honkai Star Rail Cavern of Corrosion Challenges

To unlock Cavern of Corrosion challenges, you'll need to encounter one in the Corridor of Fading Echoes while completing the The Star are Cold Toys Main Story Mission, near the end of Chapter One.

There are six Cavern of Corrosion Challenges in Honkai: Star Rail. They house 12 different Relic Sets, two at each location. Keep in mind that Relic Sets only include four types of Relic Pieces: Head, Hands, Body, and Feet. The other two types of Relic Pieces, Planar Spheres and Link Ropes, can only be obtained in the Simulated Universe.

Every time you want to collect rewards from Caverns of Corrosions, you'll need to spend 40 Trailblaze Power. You won't be able to farm the best Relics efficiently until you are able to to tackle Difficulty Level VI challenges. Because of this, we don't recommend that you spend much time or Trailblaze Power attempting to obtain Relics until you are ready to get the best.

Honkai Star Rail—Cavern of Corrosion, Path of Gelid Wind Location

The Cavern of Corrosion: Path of Gelid Wind holds the Hunter of Glacial Forest and Eagle of Twilight Line. It is found in the Storage Zone of Herta Space Station. The first set is great for Ice DPS characters such as Herta or Yanqing. The former is better for Wind units, DPS or otherwise, so this would be great for Bronya, Dan Heng, or Sampo.

You'll be fighting in two battles, which include several different enemies: a Voidranger: Trampler, Voidranger Reavers, Voidranger Eliminators, and a Voidranger Distorter. They have a mixed bag of weaknesses, but most predominantly, Physical, Wind and Imaginary.

Best Team Comps for Cavern of Corrosion: Path of Gelid Wind

Because this Cavern includes enemies from the beginning stages of the game, as long as they are properly leveled, a team of Physical Trailblazer, March 7th, Dan Heng, and Asta, would probably do fine. Here's an another example of an all four-star unit team you could use to face this challenge:

  • Natasha, Sushang, Dan Heng, and Sampo

If you have either Clara, Welt, or Bronya, they can be substituted into this team. Welt and Bronya would likely replace Sampo. Clara would make a good substitute for Sushang.

Honkai Star Rail—Cavern of Corrosion, Path of Jabbing Punch Location

You can find the Path of Jabbing Punch Cavern of Corrosion in the Silvermane Guard Restricted Zone on Jarilo-VI. It houses the Champion of Streetwise Boxing and Thief of Shooting Meteor Relic Sets. The first does really well with Physical DPS characters like the Physical Trailblazer, Clara, or Sushang. The second set is universally good on most attackers and can be used effectively as a two or four-piece set. We recommend it for units with bounce skills that can attack both mobs and bosses effectively, like Asta.

This battle will pit you against robotic enemies—an Automaton Grizzly, Automaton Beetles, Automaton Hounds, and Automaton Spiders. Lightening units will be key here.

Best Team Comps for Cavern of Corrosion: Path of Jabbing Punch

Here's an example of a four-star unit team we can recommend for this fight:

  • March 7th, Serval, Arlan, Tingyun

You could also use Bailu in the place of March 7th as your sustaining character in the team. Just be aware that Arlan prefers to fight at low health with a shield, so you might want to replace him with another DPS unit that would be effective against the Grizzly, such as Asta or Hook.

Honkai Star Rail—Cavern of Corrosion, Path of Drifting Location

This will be the first Cavern of Corrosion that you find in the Corridor of Fading Echoes, and subsequently text Welt about. It holds two important Relic Sets—the Passerby of Wandering Cloud and the Musketeer of Wild Wheat set. The first set you'll need for your healers, Bailu or Natasha. The second set is more of a Universal DPS set. It can be used as a two-piece or four-piece set and helps most units but is not the best in slot for any characters that we know of right now.

You'll be fighting Fragmentum monsters here— a Searing Prowler, Incineration Shadewalkers, Imaginary Weavers, and Frostspawns. Here again there is a general mix of weaknesses to take into account.

Best Team Comps for Cavern of Corrosion: Path of Drifting

Because you can't take advantage of every weakness, we recommend focusing on the weaknesses of the boss: Ice, Lightening, and Imaginary. Here's an example of a four-star team you could build to face this challenge:

  • March 7th, Serval, Tingyun, Arlan/Herta

If you have either Bailu or Gepard, they can replace March 7th, but again, be wary for using Bailu with Arlan. Welt can also be subbed into this team, likely taking the spot of Arlan or Tingyun.

Honkai Star Rail—Cavern of Corrosion, Path of Providence Location

The Cavern of Corrosion: Path of Providence can be found on Everwinter Hill, past the Echo of War Challenge you unlock by defeating Cocolia the first time. Here you can obtain the Guard of Wuthering Snow and the Genius of Brilliant Stars Relic sets. Both of these sets are a little more niche, but the first works well for March 7th, Fire Trailblazer, or Gepard. The second for Seele or Qingque.

More Fragmentum monsters can be found here. They include: a Decaying Shadow, Imaginary Weavers, Incineration Shadewalkers, and Frostspawns.

Best Team Comps for Cavern of Corrosion: Path of Providence

The Decaying Shadow is a formidable enemy so focus in on it's weaknesses, Fire, Wind, and Lightening. Don't forget, you'll always need to keep a Sustaining unit in your team as well. Here's our four-star team example.

  • Natasha, Asta, Serval, Dan Heng

If you have Bailu, you could use her in place of Natasha for an Elemental advantage. You could also replace Asta with either Himeko or Bronya, if you happen to have those characters.

Honkai Star Rail—Cavern of Corrosion, Path of the Holy Hymn Location

This Cavern of Corrosion can be found in Cloudford on the Xianzhou Luofu. It holds the Knight of Purity Palace and Band of Sizzling Thunder Relic Sets. The first set is particularly good for shielders and is another option to use for Gepard or March 7th. The second is best in slot for Lightening DPS characters like Arlan and Serval.

You'll be fighting a Blaze Out of Space here, as well as Imaginary Weavers, Thunderspawns, and Masks of No Thought. They largely share weaknesses to the Physical element, so plan to use at least two characters with that element.

Best Team Comps for Cavern of Corrosion: Path of the Holy Hymn

Here's an example of a four-star unit team we can recommend for this fight:

  • Natasha, Physical Trailblazer, March 7th, Sushang

If you have some on-element five-star units in your roster, Clara, Yanqing, or Seele, they could replace the other DPS units in this team or even a Sustainer. Make sure to keep at least one healer or shielder in your team, though. Gepard could also replace March 7th if you choose.

Honkai Star Rail—Cavern of Corrosion, Path of Conflagration Location

This last Cavern of Corrosion, the Path of Conflagration is on the lower level of the Stargazer Navalia on the Xianzhou Luofu. Here you can find the Firesmith of Lava-Forging set, which is great for Himeko or Hook, as well as the Wastelander of Banditry Desert, which works well for Welt.

There are several enemies in this challenge that are unique to the Xianzhou Luofu, including an Aurumaton Gatekeeper, Mara-Struck Soldiers, Entranced Ingenium: Illumination Dragonfishes, Entranced Ingenium: Obedient Dracolions, and Entranced Ingenium: Golden Cloud Toads. There are a lot of Weaknesses you could choose to aim for, but the game recommends Lightening, Wind, and Quantum.

Best Team Comps for Cavern of Corrosion: Path of Conflagration

Here's an example of a four-star unit team we can recommend for this fight:

  • Natasha, Serval, Dan Heng, Tingyun

Of course, if you have Bailu, she could replace Natasha. Tingyun could easily be replaced by Bronya, and Seele could take either Dan Heng or Serval's place.
