During the Honkai: Star Rail “Ones Fallen into the Abyss” Trailblaze Mission, you’ll eventually need to use Findie the Interastral Peace Corporation object finder to collect mine cart parts. However, the game doesn’t explain how to do so. It gives you the ability to place seven pieces of Findie at a time, highlights an area and leaves you to it while the character spouts ads repeatedly for things you don’t need. In case you missed the tutorial message or just want to know where the items are, here is how Findie works.
How to use Findie to find mine cart parts in Honkai: Star Rail “Ones Fallen into the Abyss”
The key here is to place the seven pieces of Findie and look at the color and direction of the beams. The search will limit you to an area in yellow on the map. The item can only be around there. Place the first Findie somewhere. Look at the color of the beam. If it is pointing in a direction and red, it is very far away. If the color is yellow, it is further away in that direction. If it is green, it is very nearby and you should probably take a few steps in that direction and place another Findie part.
The part closest to the broken mine cart is the Mine Cart Pin. Place one FIndie piece right next to the treasure chest to get it. Findie will say they found it, and there will now be a point you can investigate to collect the object.
Now, the Mine Cart Wheelset is even easier to find. Go to the Calyx (Golden) in the new yellow highlighted area. Place a Findie part right there. The item is to the left of it, and it will immediately pick up on the radar.
Once that’s done, head back to the mine cart. You can use the two items there, Seele will fix it, and you’ll be on your way.
Honkai: Star Rail is available for PCs and mobile devices, and PS4 and PS5 versions are in development.
