Weapon Magnet

After you draw matching runes, one on a hand, and one on an object of choice, you touch both then enchant them. That grants the object thrown properties, and the user the ability to return it back to their hand (The user being the person that has a matching rune on their hand). Each pair of runes is different. The speed of the object is as if it's falling. When the object reaches the user's hand it immediately stops, having no recoil, and dealing no damage. Only the activation uses a spell slot.
