The Trainer is the new feature in Head Ball 2 to enhance your gameplay, strengthen your characters, and give benefits. You can see the Trainer button on the main screen to select your Trainer.
There are 4 different Trainers for now, but there will be many more. Each Trainer has a different feature that will increase your power, or boost your earnings from the matches.
There’s a Common Trainer that you can select anytime, and he has unlimited time. You can select other Trainers in exchange for Emeralds or you can simply purchase them on the Trainer tab.
There are also Rare, Legendary, and Heroic Trainers that can give you powerful boosts and more.
You can purchase the Trainer you like on the Trainers screen. You can receive; EXP Boost, Power Boost, Point Boost, Skill Boost, Fan Boost, or Gold Boost from the trainers.
Unlike the Common Trainer, the rest of the Trainers will leave after spending a specific amount of time with you.
