You may have noticed while playing Honkai Star Rail that you’ve received both Planet Spheres and Link Ropes while playing through the main quests, but you only got two of each. So where do you find more of these items?
In this guide, we’ll let you know exactly where to find both of these items so you can get back to your star-crossed adventure.
Where to Find Planet Spheres and Link Ropes in Honkai Star Rail

Before you can find anything, you first need to complete the mission “No time for Me, My Friend.” Once this mission is complete, you can find both Planet Spheres and Link Ropes.
The best way to find these items is by going to the Cavern of Corrosion and Simulated Universe, then look for an Immersion Reward.

You can open these Immersion Rewards by using tokens. You can find tokens during gameplay or at the shop.
If you don’t have tokens to receive the reward, you’ll have to use stamina, which is not ideal.
You won’t be able to find these items in chests, so you’ll have to plan accordingly if you want to farm Planet Spheres and Link Ropes.

When it comes to the Cavern of Corrosion, there are six main locations:
- Path of Gelid Wind
- Path of Jabbing Punch
- Path of Drifting
- Path of Providence
- Path of Holy Hymn
- Path of Conflagration

When it comes to the Simulated Universe, you’ll have to make your way through each world in search of Immersion Rewards.
Finally, there is one more way to obtain these items, and that’s by crafting them. Unfortunately, you won’t be able to do this until you reach Trailblazer 40.
That can be a tough time for many players, so it’s best to head to the Cavern of Corrosion and the Simulated Universe if you’re under-leveled.
