Events
New Trailblaze Mission

The continuation of the Honkai Star Rail story in Penacony, going deeper into the secrets behind the family, dreamscape, and companions you encountered on the vibrant planet of festivities.
New Areas

Centered around the beloved animated icons of Penacony. The park is split into three themed zones: Clockie's Screening Area, Hamster Ball Park, and the Hanu Gang Base. Create your own animation, produce a spin-off, explore, and discover treasures!

Located in the Moment of Morning Dew, serves as the headquarters of the Oak Family and belongs to Mr. Sunday.
Vignettes In A Cup

Inspired by the concept of real-life lounges or late-night diners where customers often gather to pour out their hearts. The manager of the Dreamjolt Hostelry is away and has entrusted you to take over the role of the drinksmith.
Sounds ordinary, but instead of catering to your typical Penaconian clientele or Dreamchasers, you will serve certain monsters living within the Dreamscape.

Once you have completed the Dreamjolt Hostelry assignment, you obtain a specific 4-star character.
Tides of War

Another Stage Combat in which Trailblazers fight monsters and rack up Grit Value. By leveling up their Grit Phase step by step, they can reach the ultimate Grit Phase, that's when they gain the “Might Unleashed,” where players get powerful Stage Buffs.
New Game Mode

A game mode where players must dodge enemy attacks and obstacles to complete challenges. Triggering Turbo Dash and picking up refill items to accumulate energy, allowing players to perform sprint.

Expect newly added puzzles and the transformation of our favorite Hanu with a brand-new upgrade. Hanu got his hands on a brand-new powerhouse item, Rocket Launcher.
New Boss Enemy

| Ten Stonehearts: Aventurine of Stratagems |
|---|
| The new Boss in Honkai Star Rail 2.1 who occasionally unleashes a torrent of chips to attack the players while engaging in an in-combat game akin to Blackjack. The Boss will throw two or more diced onto the field. When players attack each die, they will get a random point. If their points are higher than the Boss', they win the game and gain some advantageous effects in battle. However, if player's points are lower than the Boss', he will pummel them with a rain of chips. |
New Simulated Universe (World 9)

Trailblazers can start their new challenge from Difficulty IV and obtain all the First-Time Completion Rewards of the difficulties leading up to it.
Use immersion devices to obtain the Planar Ornament sets Sigonia, the Unclaimed Desolation, and Izumo Gensei and Takama Divine Realm.
New Planar Ornament Sets

| Izumo Gensei and Takama Divine Realm | Sigonia, the Unclaimed Desolation |
|---|---|
| Increases the wearer’s ATK by 12%. When entering battle, if at least one other ally follows the same Path as the wearer, then the wearer’s CRIT Rate increases by 12%. | When enemies are defeated, the wearer’s CRIT DMG increases by 4%, up to 10 times. |
One-Year Anniversary Special Event
