I'm making a 2D RPG similar to Lufia with my group, and I'm trying to think up a good battle system. I'm thinking of having STR, INT, DEX, and CON. These are what I call the "prime stats", as they affect other stats, like AC, Accuracy, ToHit bonus, Damage bonuses, resistances, MHP, MMP, etc... Now I'm trying to think up a good way to combine these for battle. Something like you roll (Accuracy+ToHit bonus) and if that is greater than the enemies AC than you hit them for (weapon damage+damage bonus-enemy Armor). Hmmm, now that I think about it that sounds like a decent way of doing it...

Hmm, now how to derive the smaller stats from the prime stats?

MHP=CON+(STR/2)?

MMP=INT+(DEX/2)?

Hmmm, If I could combine all 4 prime stats in some way to come up with 4 other small stats, based on the combination of 2 primes...

Thanks for reading my thinking process heh, any input is appreciated :)
