• Mind - Influences XP gain and TP amount.
• Body - Affects physical attacks, movement speed, and evasion ability.
• Spirit - How spiritual you are. High spirit affects how much magic affects you i.e. you deal and receive more magic damage/healing. Basically works the same way the faith attribute does on Final Fantasy Tactics.

I've never really been a fan of having 6+ attributes, especially when no single class makes heavy use of all of them to begin with. Might as well cut the fat.
