Shadow Snatching is an art form, not a science.
But, for the sake of this handbook, let's pretend it's a science, shall we?
First, you'll need to find your shadow. This may take some time, as shadows can be notoriously difficult to locate. Try looking for the dark shapes lurking just out of sight, or the faint outlines of your enemies.
Once you've found your shadow, it's time to snatch. This is the fun part! Use your trusty shadow-grabbing tools (available at your local occult shop) to snatch that shadow and bring it to the light of day.
But, be warned: Shadow Snatching is not for the faint of heart. It requires a certain je ne quarter, a certain joie de vive for the hunt. Are you up for the challenge?
