Im thinking there should be Bromon battles in the game where you would fight online for Brox or maybe get to steal your opponent’s Bromon.
I think every time you enter a battle you see a menu page where you select the Bromon you want to fight with and the backpack items that you’d like to use. Both players must click a accept button to start the battle. If your opponent changes what they chose after you clicked the accept button you will have to click it again. After both players have clicked the accept button a three second count down comes before the battle begins.
When the battle begins both players will engage in a battle like normal except that the buff wheel can not appear. You can also challenge a friend to a battle but you can’t gain rewards from that to stop acount transferring Bromons.
