This is the second minigame for year 6. For this one you will need to spin around to cast stupify on each Inferi coming at you. Hold them all off keeping as much of your health as possible. You have a minimap with the Inferi locations on it that will work as long as you have light, if your light goes out raise your hand opposite your wand hand. Hit one far away because you will be graded on furthest hit, its an instant 100 for that category if you do so. You can afford to be bit twice by an Inferi and still get 5 stars as long as you get a 100 in the "longest shot", and "Inferi hit" categories.
