Home Screen

Avatar and Spirit
They are the icons in the top left corner. The avatar is the character you create, and the Spirit is the pet you receive in the game after Quest 14, which helps you in battle. Tapping on these will allow you to change both of their outfits, clothes for the avatar and the animal for the Spirit (“KHUX ~ For Beginners”). On the avatar, you can also change the name, message, and title. For the Spirit, you can change its name and gear (medals to strengthen it), and you can see its tricks, which help you in battle like reviving you, boosting damage, dealing damage alongside you, etc. (Kingdom Hearts Union X [Cross]).
Lux
The first blue bar on the top of the screen, Lux is the resource you collect from battles that helps you level up. The number above tells you how much more you need to reach the next level. And the level you’re on is to the left of it (“KHUX ~ For Beginners”).
Ability Points (AP)
The yellow bar in the center on top of the screen, AP allows you to play the multiple levels in the game and is the ‘free-to-play’ element of the game. It varies on each level. When you use them, it takes three minutes to refill one AP (“KHUX ~ For Beginners”). To increase the number, you have to buy them on the Avatar Boards (Kingdom Hearts Union X [Cross]).
Jewels
To the right of the AP bar, jewels are the ‘pay-to-win’ element of the game. You are given some daily for logging in, completing quests and events, and occasionally as gifts during important dates and holidays, like Christmas and the recent release of Kingdom Hearts 3 (“KHUX ~ For Beginners”). You can use them to buy new medals/attacks from the shop and for premium avatar boards (Kingdom Hearts Union X {Cross]).
Chat
The speech bubble icon on the top right is the Chat feature. Here, you are able to talk with the other members of your team. Whatever you write is sent to everyone. If there’s an exclamation point showing, there is a new message (“KHUX ~ For Beginners”).
Menu
The Menu button in the far top right corner gives a dropdown menu of what is already on screen. The only exception is the Other option. When Other is selected, you get another menu with more options. They range from seeing your news, union transfer, a theater to watch cutscenes, and frequently asked questions (Kingdom Hearts Union X [Cross]).
Missions
The Mission button is right under your level. Here, you can complete daily, weekly, and monthly missions to win rewards. The rewards are jewels and Spirit parts (Kingdom Hearts Union X [Cross]).
Lux Boost
The Lux Boost button helps you to gain more Lux for each battle won. It provides a 5% boost in the total Lux you earn for one hour. If you join a team, the max number of people allowed is thirty. If everyone does this, then there would be a 150% boost in Lux. You can use it only once per day, renews at midnight (Kingdom Hearts Union X [Cross]).
