Levelling Up:
Leveling up your Roomies improves their base stats (Fitness, Wit, Charm, Luck, and Style). Leveling up requires Roomie XP Bars. XP Bars can be earned by completing collab encounters, or from other rewards such as Boxes and Contests.

                               
                                        Levelling up will require XP Bars.

Tiering Up:
At every 10 levels, you’ll need to upgrade your Roomie’s Star Tier before they can level up any further. You can upgrade your Roomie’s Star Tier by using Roomie Stars of the corresponding rarity. Roomie Stars can be earned from opening up Roomie Power Up Boxes, but they also have a chance of dropping from PVE (Collabs/Drama) or other rewards!

   
                                                                       Tiering up requires Roomie Stars. 

Upgrading up your Roomie’s Star Tier does two things:

• It unlocks 10 additional levels.
• In most cases, it unlocks a new Talent!

Talents:
These are powerful abilities that can give your Roomie an edge in all sorts of encounters. They are crucial if you want to make it to the top! Once a Talent is unlocked, you get Level 1 of that Talent as a freebie. Level up your Roomie’s Talents to become the most powerful by investing Roomie Pops.

Here, we've unlocked the first of Kara's talents! We'll have to keep levelling and tiering her up to unlock all of her Talents.

Lastly, equipping and upgrading your Roomies’ furniture will also give your Roomie encounter boosts!
