Farewell, Seven Rest Days is an achievement that can only be obtained if you have the character Sunday. Alternatively, you can borrow another player's Sunday from their character showcase to unlock the achievement. Obtaining the Farewell, Seven Rest Days achievement is fairly easy, as all you have to do is fight The Great Septimus Boss (in the Salutations of Ashen Dreams Echo of War) using Sunday, and ensure that Sunday deals the final blow to the boss.

Follow these steps to obtain the Farewell, Seven Rest Days achievement in Honkai Star Rail:

Step 1: Add Sunday to your team

If you have Sunday in your character line-up, add him to your team. If you don't, you must add a friend's support Sunday to the team. Make sure to add other damage-dealing characters to the team.

Defeat the first two phases of the boss using your DPS characters. Once the third phase starts, focus on reducing the boss's HP as much as you can using your damage dealers. However, do make sure you don't accidentally defeat the boss using the other characters.

Time your characters' attacks in such a way that by the time the boss's HP is at 1-2%, it will be Sunday's turn to attack. Finally, use Sunday's Basic ATK to hit and defeat The Great Septimus. Doing so will automatically grant you the hidden achievement "Farewell, Seven Rest Days".

This achievement is added to the Eager for Battle achievement section and will reward you with five Stellar Jades.
