Relics are introduced a few hours in Honkai Star Rail, but it will take a while before you get any decent ones. Thankfully, one of the best methods of farming Relics comes soon after. With that in mind, you’ll want to know how to do it and the rewards you’ll get. This is our guide for the Caverns of Corrosion in Honkai Star Rail, including how to unlock the area and a complete list of all the locations you can find.

Caverns of Corrosion Explained

Caverns of Corrosion in Honkai Star Rail are repeatable dungeons that award you with Relic Sets. There are a select few across the different areas you visit and each has a special effect that modifies the battles taking place. You’ll have to use 40 Trailblaze Power to take one on.

Six difficulties are available in Caverns of Corrosion. These become available as you raise your Equilibrium level. Although the enemies remain the same, the relics will be offered at higher rarities.

How to Unlock Caverns of Corrosion

To unlock Caverns of Corrosion, you’ll need to play through The Stars Are Cold Toys quest. This is part of a quest line that requires Trailblaze Level 24 to start. Some will retroactively appear on your map, and others will appear as soon as you come across them in future areas.

If you’re like me and have spent some time playing Genshin Impact, you’ll recognize the similarity to the artifacts-rewarding Domains of Blessing. One key difference between that and Caverns of Corrosion is that they don’t change based on a schedule. You can farm their set of relics on any day you want.

Here, I’ve broken down all of the specifics for the Caverns of Corrosion currently available.

Even the Interactive Map from HoYoLab has some repeated locations for a couple. Regardless, all of the below information is from my time playing since Honkai Star Rail officially launched.
