I added a system that was inspired by the Blizzard game Diablo. It's simple, pretty much better ideas have different colors. White for common, blue for magic, yellow for rare, and orange for legendary. I thought it added some fun value to the game.
Eegh M Defense could be abbreviated to MDEF or you can do ATK DEF MAG MDEF AGI WIL
No crushy type!! maybe you can do some color type for magic + and Agi + darn rpg maker doing a crush!!
