"Letter to a Dim Star" is a side quest in Honkai: Star Rail that can be picked up from the young explorer Rocky, a guy from the Department of Galactic Geography. Go through the story part until the phone receives a message that activates the task.

Go to Rocky by the marker and chat with him. Leslie, a girl with whom he has been talking for a long time, does not answer the guy for a long time. He asks to repair the repeater and find out what happened to Leslie.

It's easy to complete the task, we can do without spoilers. Difficulties, no matter how, will begin at the end. After a conversation with Bernard, Rocky's teacher, you need to make a choice - tell Rocky the truth or lie.

What to choose - red truth or blue lies in Honkai Star Rail?

The decision you make now will not affect the reward for completing the quest. So here choose what you think is the most correct.

• If you tell Rocky the truth , he will decide to fight for his love. Using science, Rocky will try to reunite with Leslie. At least he's sure of it.

• If you lie to Rocky , he will be upset and disappointed in himself. Listen to his complaints about life, after which the guy will focus on research and destroy all the verse??. Leave only one poem.

How to get the "Diamond and Rust" achievement

After completing the adventure mission, be sure to visit Bernard. The man is in the northern part of the Main Control Zone, next to the teleporter. Tell the man how you completed the task.

Talk about everything, find out about his plans, and you will soon unlock the "Diamond and Rust" achievement and 5 units of Star Jade. By the way, if you talk to Bernard later, you can find out what happened to Rocky.
