Kill the enemy. :/ You can't use a Special Attack if you don't have enough MP. Same with Summons and SP (Summon Points). Attack can be used regardless.
I made this to show my friend what a Turn-Based RPG is. :D For those who want more, I'm making more! MORE MORE MORE MORE!!!!! I was going to put the versions and how each one improved here. But, it took up too much space. So, I decided to put it in the game! Just hit the Versions button!
