That'd be a grenade, more or less, which you also don't want to be anywhere near. Really, what you should do is simply have it get less and less efficient the larger the object, so it doesn't get overpowered. You don't have to do any math, even, merely have it grow slower than object size, potentially with the amount of aura necessary growing faster than object size.
