Duration of a Song is an achievement you can earn in Honkai: Star Rail if you pull Robin from the gacha. She is a requirement, but what if I told you there’s a way to get this achievement without having her directly?
How to earn the Duration of a Song achievement with no Robin in Honkai: Star Rail
For clarity’s sake, Duration of a Song is the achievement you get as a reward for watching Robin sing during her Ultimate in battle. Specifically, you need to watch her in the Checking Mode to earn credit for this achievement, which is why you need her to get it. However, there is a limited-time method you can use to snag this achievement if you’re an achievement hunter, or just want more Stellar Jades for your Robin pulls.
If you’re new to Honkai: Star Rail, every time a new character is released into the game, you have access to their Character Trial, and with Robin this is no exception. To access her Trial, open up the Warp menu and click on Character Trial down at the bottom.
This will take you to her specific trial in Penacony. Progress through the trial as normal until you get into a battle with the enemies present there. This shouldn’t take long to do because the trial is very short. Once you’re in combat, build up Robin’s energy by using her skill once, then attacking with the other present characters until Robin has her Ultimate available. As soon as it is, activate it, then enter the Checking Mode by selecting the magnifying glass plus paper icon on your screen.
Now, navigate over to Robin in the Checking Mode screen. If her Ultimate is still active, she should be grooving to the sound of her own voice here.
Watch her dance in the Checking Mode screen for a few seconds, and the Duration of a Song achievement will be yours. Be warned: This entire process can only be one while Robin is one of the Rate-up characters active. Once her character banner comes to an end, you’ll have to wait for her rerun to use this process to earn the achievement.
