Like artifacts in Genshin Impact, Honkai: Star Rail features relics as one of many ways to strengthen your character. Although you may be eager to equip the rarest equipment on your favorite unit, you will need to progress through the story quite a bit before you can access the dungeons. Without further ado, here’s a guide on unlocking the Caverns of Corrosion in HSR and all their locations.
How to Unlock Caverns on Corrosion in HSR
You can unlock the Caverns of Corrosion during “The Stars Are Cold Toys” quest, which you can start by reaching Trailblazer level 24. While progressing through the Corridor of Fading Echoes, the group will encounter the first Cavern of Corrosion.
The main character decides to contact Welt, who will explain the lore behind the mysterious phenomenon. After the conversation ends, you can immediately enter the Caverns of Corrosion you’ve discovered.
You will also find two more dungeons in Xianzhou Luofu, with the first located in Cloudford and the second in Stargazer Navalia. However, you can only access them once you can enter the new region by reaching Trailblazer level 29.
The Caverns of Corrosion are basically HSR’s version of the Domains in Genshin Impact, and you must spend 40 Traiblaze Power to enter each dungeon. Luckily, you can borrow Support Units from other players to help you in battles. Each Cavern can grant you two types of relics, and you can get five-star drops by beating high-level dungeons.
