To level your characters to the point where defeating the bosses takes absolutely no skill whatsoever. This is done in RPGs by unskilled players who avoid any challenge by spending a long time leveling on weak monsters instead of attempting the dungeons at a level that would prove at least somewhat challenging.
Lord Alex refused to go to the Floating Continent in Final Fantasy VI until he was level 40 and everyone had fully learned all the espers... that is more than overleveling!
