Honkai Star Rail 2.7 introduces an exciting new personal space customization feature where players can transform their initially empty Trailblazer room through the Cosmic Home Decor event. This limited-time activity allows you to acquire exclusive furniture pieces and decorative items to personalize your living quarters aboard the Astral Express. However, obtaining these cosmetic enhancements requires earning supply credits through strategic gameplay. The event revolves around completing character duties efficiently, and while you can replay activities indefinitely, employing smart tactics significantly accelerates your progress toward premium rewards. Our comprehensive Cosmic Home Decor guide provides the roadmap to swiftly complete your room design while securing all available limited-time bonuses.

Accessing this decorative event requires meeting a straightforward progression milestone. You must achieve Trailblaze level 21, which automatically adds the event to your Travel Log interface. Once available, simply navigate to the event section and initiate teleportation to the designated starting area. The introductory phase begins with the Cosmic Home Decor Guide: Prologue mission, which activates upon arriving at the Party Car location through the Travel Log menu.
After completing the prologue mission and unlocking event access, the primary gameplay loop commences. The central mechanic involves a strategic card-based movement system where each Action Card’s numerical value determines your advancement distance across the game board. These cards feature various Astral Express crew members alongside special guest characters, with each selection contributing to that specific character’s duty completion tally. For instance, choosing a Dan Heng card increments his personal duty counter.

The game board consists of various tile types that trigger specific events when landed upon. Strategic navigation to beneficial tiles can dramatically enhance your resource acquisition. Following the expenditure of a predetermined number of Action Cards, each day concludes with a mandatory report submission phase. During these dinner meetings, you must present characters with the highest duty completion rates to accumulate points and achieve superior evaluations from Pom Pom. Your final score directly correlates with the quantity of supply credits earned, which function as the primary currency for furniture purchases.
The leadership role rotates after completing three dinner meeting phases, with each new leader introducing distinctive abilities and modifying daily duty requirements. This rotational system encourages adapting your strategy to leverage each character’s unique strengths, similar to how understanding different combat roles can enhance your performance in our comprehensive Class Guide for optimal team composition.
When deploying Action Cards, consistently analyze the upcoming tile sequence to maximize beneficial landings. Calculate your available card values to strategically position yourself on event tiles whenever possible, with particular emphasis on multiplier tiles that amplify your earnings. Additionally, exercise caution to evade catastrophe tiles, which are clearly marked with distinctive exclamation point indicators and typically impose penalties or resource deductions.

Every completed duty increases the corresponding character’s proficiency level, and experienced players recommend concentrating efforts to maximize one character’s development, preferably the current day’s leader. This focused approach streamlines dinner meeting report preparation and enhances scoring consistency. Proper character specialization mirrors the strategic approach needed for weapon mastery, as detailed in our Weapons Unlock guide for combat optimization.
Common Strategic Errors to Avoid: Many players underestimate the importance of saving high-value cards for critical movement sequences, resulting in missed multiplier opportunities. Another frequent mistake involves spreading duty completion too evenly across characters, which diminishes your scoring potential during dinner meetings. For comprehensive event understanding, consult our Complete Guide for additional gameplay insights.
Time Investment Considerations: Efficient players can typically complete the core event activities within 2-3 hours, while comprehensive completion with all rewards may require 4-6 hours depending on strategic execution. Advanced optimization techniques can reduce this timeframe by approximately 30% through careful card management and tile prediction.
