The Badlion Client has a built-in emotes feature. You can express your current emotional state through these emotes.
NOTE: Emotes can cause significant FPS drops. To prevent this, you can choose to disable the emotes feature completely. Open the Badlion Client slideout and navigate to the Graphics tab. You should find a setting called "Emotes". If the button's grey, then it's disabled. If it's blue, then it's enabled.
You can open your emotes quick selection through pressing the "B" button. Navigate through this wheel by moving your mouse, or press the keybindings on your keyboard.
To change the emotes quick selection, press the "H" button. You will find a list of available emotes, which you can search through. All the keybindings of the emotes feature can be changed in this menu. You can select any of the 6 available emote slots by clicking on their position in the wheel. After you've selected the right part of the wheel, select the emote you want to use in that part. You can change the keybinding through the "Emote Keybind" button.
