No, I mean like you buy spells and stances but having a new part in the battle window labelled 'skills' which would have attacks like power break, steal etc these could be purchased like spells and stances are.
 
Steal could be used to possibly obtain an item that a specific enemy uses in battle ie: elixers.
 
Power break could lower an enemy's STR value temporarily.
 
^ my ideas.

 A bigger map can only last so long, having extra maps can make it easier to create new areas. Not to mention it would take ages to load up a larger map due to the data so extra maps would probably be better.
 the new maps could be Spira/Gaia or something new. The new maps could either have a storyline that is new new or follow the same one, or be a kind of arena with overpowered enemies for the RPG elite?
