A few years ago I learned that those magical rocks that somehow change your life/luck/fortune actually have charge, and when the charge runs out you have to recharge them... with a magical rock that recharges magical rocks.

The recharging magical rock is also significantly more expensive than the other magical rocks.

Can I borrow your rock charger bro? I forgot mine
