Explore: point your right index finger — you walk toward it. Blue shrines heal. Pinch (thumb+index) to drink a Wiggenweld potion.
Fight: keep your wand tip ON a Death Eater to charge. When he freezes, hold the shown hand signs in order. Your LEFT open palm raises a Protego shield against his bolts.
Grow: kills fill the silver Patronus bar — when it's full, show both palms to unleash the stag. Every spell has its own power. Slay the Dark Lord at the far east.
