Using a Disillusionment charm on yourself was very clever, but it won't hide you forever.

The path you've chosen takes you longer, but you eventually approach the center of the forest. Your last Hominum Revelio spell reveal a middle-aged woman huddled on the ground, shaking with fear. She can't see you because of your Disillusionment charm and continues screaming.

Suddenly, the fog thickens, and an overwhelming sense of despair hangs over the forest. A dark cloaked figure emerges from the shadows, extending a slimy, scabbed hand toward the woman.

Without your help, she doesn't stand a chance!
