How to get I Killed Myself? achievement in Honkai Star Rail

Honkai Star Rail 2.7 has introduced many hidden achievements, including I Killed Myself?, which can be obtained by defeating the Phantylia boss using Fugue, a 5-star unit in the game. To get it, you need to own the character or use her as support from someone else.

With Fugue in your team, head over to the Echo of War: Divine Seed in Scalegorge Waterscape to challenge Phantylia. It is recommended to choose one of the lower difficulty levels (either Difficulty Level I or II) for the fight, as this will make it easier to obtain the achievement.

Steps to get I Killed Myself? achievement in Honkai Star Rail

Follow these steps to obtain the I Killed Myself? hidden achievement in Honkai Star Rail 2.7:

Step 1: Add Fugue to your team

If you have pulled for Fugue and own her, add her to your team. In case you don't have her, select one of your friend's (or a stranger's) Fugue to add to your team lineup. You can include one DPS character in your team if you want, but since you will be playing on a low difficulty, you don't need to choose a top-tier DPS. Any moderate damage-dealing character will suffice.

Step 2: Complete the first two phases

For the first two phases of the boss fight, try to defeat Phantylia normally. It should be relatively easy, considering her HP will be significantly reduced when playing on a lower difficulty.

Step 3: Use Fugue to deal the final blow

In the last phase, bring Phantylia's HP down to 2-3%. Then, use Fugue's Ultimate or Basic Attack to deliver the final blow to the boss and defeat her.

Upon doing so, you will instantly obtain the "I Killed Myself?" hidden achievement. It will be added to the Eager for Battle achievement tab, and you will receive a reward of five Stellar Jades for it.
