Are you a Witch, Wizard, Magician, or a MacGyver?
Either way, you will need your wand to retrieve this cache from the serpent. If you're a MacGyver, you can figure it out when you get there. Your wand can be "attractive", hooked, or just straight. You will need to bring your wand or fashion one from the forest to retrieve this cache.
Watch out for Nagini, she is nearby and watching your every move.
