Mage Hand is more far reaching than simply reaching far.
Ever want to pop off your hand and throw it across the room? Try Mage Hand instead. It's a cantrip that has an incredible variety of uses, and they're all fun as heck. Well, I'm sure you could fold laundry or something, but you're playing D&D here. Well, then again, if laundry's your jam, go for it. The lesson is there's very few situations in which you shouldn't cast Mage Hand.
When discussing this gripping spell we first go to Kinship Camp to discuss how to make the most of Mage Hand in role-play. First, you've gotta figure out what yours is like. Don't hold back. Creepy, with long nails and decaying skin? Angelic, soft as a rabbit and faintly glowing? How do you control it? Moving your hands? Is there a laser beam of energy connecting it to you, or just faint wisps trailing through the air? Then we talk endless possibilities from easy distractions to cheap scares. Framing people to making them fall down a chasm. And don't forget how lazy your character can become with this spell. Finally we apply it to some specific characters and see what happens.
Then it's over to Milly's Shop of Wonders to come up with some ridiculous magic items that are Mage Hand based. If you actually use them, we can't trust you anymore. So go forth, and use this knowledge for good! Or for hi-jinks, we don't mind.
