A well appears within range in an empty space. It is a circular well 5ft in diameter that glows a bright blue. A golden coin appears in your hand. If your hand isn't available, it will pop in your pocket. If you have no pockets and your hands aren't free, the coin will appear at your feet. If you have no feet, then what the hell. Wish for literally anything, and that will come true. It takes an action to cast the spell, and an action to throw the coin the the well. Anything will come true. The only thing you cannot wish for is more wishes.
