How to Play Cosmic Home Decor Guide

Renovate the Trailblazer's Room

All Trailblazer's Room Decorations

Assign a Team to Conduct Duties

Players will need to accomplish chores with a Duty Squad and earn Express Funds, which are necessary for the renovations. Certain characters will have their own Leader Trait and initial Meeting Ability.

As you conduct more duties, the Duty Squad will be rotated around to switch leaders or add new members. Eventually, you'll even be able to select which Duty Squad lineup to go with!

Take Note of Action Card Effects

During duties, you'll use Action Cards to advance forward and encounter different types of event tiles. The number on the Action Card determines which tile you'll land on, so be sure to plan your steps carefully!

When using the Action Card of a certain member, their Duty Level will also increase based on the number. Be on the lookout for Gold-colored Action Cards as these can also give better benefits!

Get Evaluated in Dinner Meetings

At the end of a round, Pom-Pom will give you extra Express Funds based on a performance evaluation! Each member's contributions will be presented as cards, and you'll need to choose the ones to submit for your report. You can also discard cards with Mental Reset!

If your deck has multiple cards from a certain member, you can submit them together to gain points based on their level. Try to raise each member's level during duties as much as possible so you can gain even more points!

Use Meeting Abilities to Boost Your Score

During duties, you can also obtain various types of Meeting Abilities. Depending on their effects, you can further increase the points earned from the cards you submit! Be sure to check out the details of your obtained abilities to make the most of them.
