This is the last minigame of year 6. This minigame was tough for me until I got the hang of it, you will use your wand hand to block all three waves of Harry's spells at you. They will get faster and faster so you need to do the same. Try to hit as many as possible because you will be graded on that, get hit three times and you need to start all again. You can dodge the spells, so if you need to just start strafing and hitting the spells, I thought it was easier to stand still the majority of the time though.
