Cosmic Home Decor Guide

Main Menu

Let's introduce the main page first. Look at the box in the image above. The icons show how many rooms you need to renovate aka it will track the room's renovation progress.
There are a total of 6 rooms that you'll need to decorate: Bedroom, Bathroom, Entryway, Living Room, Game Room, and Display Room.

To renovate those rooms, you'll need Express Funds. These funds can be obtained by completing duty in the Astral Express.

Lastly, the Duty Roster and Renovation Subsidy. Simply put, those 2 are the rewards and bonuses you will get by completing renovations of the rooms and raise your Decor Rating. Same as the Character Selection and Limited-Time Rewards.

Express Duty

Action Cards & Duty Schedule

In the Express Duty, all you need to do is select an Action Card (at the bottom right) to progress your duty schedule (top left). The Action Card will also raise the corresponding member's Duty Level - something that you will need for the next step.

Different Action Cards entail varying workloads (which doesn't really matter). What matter is the number on each Action Card. After selecting an Action Card, the schedule will advance by a number of steps to reach the corresponding tile.
Note: It's like playing Monopoly where you need to advance tile by throwing dices. But in this event, you can choose what number the dice will be.

Tile Effects

An effect will be triggered based on the tile you stop on. When selecting Action Cards, try to get the advantageous tiles and avoid the dangerous ones.

Leader Trait

Each round of Express Duty will feature different leader aka different bonus effects. Make sure to read them so you can maximize the effects and get the highest score possible.

Dinner Meeting

Remember how selecting Action Card will also raise the corresponding member's Duty Level? This is where the Duty Level plays their role.
Dinner Meetings will be held periodically in the schedule (you can see by the Pom Pom tile in the schedule), and you can gain a large amount of Express Funds based on your report results.

During the Dinner Meeting phase, you can select and submit Duty Reports to obtain Express Funds based on the score received by Pom-Pom.

Duty Level Affects Base Score

The higher your members' Duty Level, the higher the base score of their corresponding Duty Report will be as well.
How to increase Duty Level?
> You need to choose the corresponding character's Action Card during the duty schedule. For example: If you choose Himeko's Action Card, it will also increase her Duty Level.

When submitting similar reports, you can create a report bundle, increase your score efficiency, and obtain higher scores from Pom-Pom. But this only works for the same character.
For example: If you have 2 Himeko Reports, and her Duty Level is Level 19. The base score will be increased to 38 (19 from her Duty Level x 2 of her reports). If you slip in another character in the bundle with lower Duty Level, it will be discarded and not counted to the points.
In short, the more reports of the same characters you submit, the higher the score efficiency will be.

Mental Reset / Discard Duty Report

Using "Mental Reset", you can discard selected reports and draw the same number of new ones. Pleaes note that each team member has a limit on the total number of reports.

Aside from using Mental Reset, you can also discard selected reports by submitting it. Hear me out first! So, only the same character's report (with the highest Duty Level) will be counted by Pom Pom. If you bring other characters with lower Duty Level, it will be ignored by Pom Pom. But, that also means that card will be discarded and you can get new card!

Meeting Ability

Meeting Ability is somewhat of a buff that will increase your scores. You can hold a maximum of 5 Meeting Ability. If you got more than 5 on the duty schedule, you need to discard one of them.

How to get Meeting Ability?
1) Leader's of the squad will provide 1 Meeting Ability (except Himeko in the tutorial phase)
2) Go to Inspiration Tile (the tile with character's face on it)

What if you get the same Meeting Ability?
Said Meeting Ability will stack and increase the effect.

Get as high of a score as you can from Pom-Pom within the limited number of "Mental Reset" and "Submit Report" attempts. Do your best to each Express Funds!
