Harry Potter: Quidditch Champions

The You’d Make A Fair Beater achievement can be obtained very early in the game.

The Beater tutorial is the third tutorial you’ll be introduced to, after Keeper. The Beater training has two stages:

• Beater Practice

• Beater Match

Once you complete the Beater Match stage, the achievement should unlock! If for some reason you aren’t taken into the tutorial automatically, you can access it by going to the main menu and going to Play > Press A > Campaign > The Weasley Burrow Garden Cup > Beater.

I hope this helps!
