The Seal Slammers event in Honkai Star Rail has launched, offering players the opportunity to engage and earn a variety of rewards, including Stellar Jades. This event becomes accessible automatically for Trailblazers who have completed the “Witch’s Mirrored Reversal” Trailblaze Mission. If you haven’t completed this mission yet, you can still unlock it through the Finality’s Cision feature.
In this guide, we will detail how to navigate the Honkai Star Rail Seal Slammers event and how to obtain Bubbles, the adorable free pet.
Complete Guide to the Honkai Star Rail Seal Slammers Event
The Seal Slammers event is designed to be user-friendly. Participants must form a team of baby seals and successfully knock out their opponents. The event is divided into three distinct phases: Group Stage, Elimination Round, and Championship.
Group Stage Completion Strategy
To successfully navigate the Group Stage, your task is to defeat three opponents: Timos, Perhippas, and Tribbie.
1. Timos Strategy

For this battle, the ideal team configuration includes:
- Bubbles
- Mega Seal
- Common Gray Seal
Utilize the Mega Seal to amplify your seals’ attack power. Prioritize enhancing Bubbles to trigger its extra turn with every opponent knocked down.
2. Perhippas Strategy

Defeating Timos rewards you with a Seal Token, which can be spent to unlock a new seal. It is advisable to unlock the Rubber Seal for its ability to enhance its own attack power upon impact.
For the match against Perhippas, consider this team setup:
- Rubber Seal
- Bubbles
- Mega Seal
The Rubber Seal’s self-boosting ability significantly aids in this encounter, while the Mega Seal continues to provide an attack boost to your team.
3. Tribbie Strategy

Before facing Tribbie, unlock the Bandaged Seal to enhance your chances of victory.
Utilize this lineup against Tribbie:
- Mega Seal
- Bubbles
- Bandaged Seal
The Bandaged Seal’s attack power increases when its health falls below 25%, providing crucial advantage during intense phases of the match.
Elimination Round Strategy

Upon successfully completing the Group Stage, players progress to the Elimination Round, where you will again face three opponents.
This powerful team composition will aid you in defeating all three competitors:
- Bandaged Seal
- Rubber Seal
- Mega Seal
This synergy among the seals significantly enhances your team’s combat capabilities. The Rubber Seal boosts its own attack, and the Mega Seal provides additional support, while the Bandaged Seal serves defensively until it can transition into an offensive role.
Championship Round Strategy

The Championship phase pits you against two formidable opponents: Dan Heng and Hyacine.
This is the optimal team setup to secure victory:
- Rubber Seal
- Angel Seal
- Mega Seal
Similar to earlier stages, this lineup offers effective synergy. However, the Angel Seal provides a unique healing ability by colliding with its teammates. If your team struggles to inflict sufficient damage, consider substituting the Angel Seal with the Bandaged Seal.
Additionally, after defeating Dan Heng, you can unlock the Ghost Seal and use it in place of the Angel Seal before the encounter with Hyacine.
Final Battle: Defeating Cipher

After becoming the Champion, your final challenge is to confront Cipher. To succeed, assemble the following team:
- Bubbles
- Ghost Seal
- Bandaged Seal
The Ghost Seal enhances the attack power of Bubbles and Bandaged Seal in each round. Additionally, Bubbles’ capability of gaining an extra turn after knocking an opponent down is instrumental in dealing significant damage, especially against Cipher’s Spiky Seal.
How to Obtain Bubbles in Honkai Star Rail

Defeating opponents in the Seal Slammers event rewards players with Seal Tokens and a unique currency for upgrading the Carnival Level. For each battle won (excluding Arena matches), you accumulate one currency. Completing the Sorty Mode grants a total of 10 of these currencies.
Upon elevating your Carnival Level to its maximum at Level 10, you will successfully unlock Bubbles as your pet.
