There is a miniscule (0.014%) chance for the very first enemies in the game to drop an extremely powerful item that normally isn't available until much later. Getting it early is absolutely wild because one of its effects is doubling stat gains when leveling up, which can quickly snowball your characters into godhood.
Bit of an obscure one, but Fire Emblem Gaiden.
