Alright then. Gonna just go with how FF would of done them if the old SNES carts had more room : http://www.gamefaqs.com/ps/197343-fi...iii/faqs/58936
Weakness: < 0%
Resist: > 0%
Absorb: > 100%
Status Imunity: 0 - 100%
That should be able to reproduce any other system without much trouble. It's also conceivable to rewrite the damage formulas and use something other than percentages too I guess...
Yeah that's a good one. .. I don't know. I guess everyone would do it differently, but I might do something like this
-Calculate damage
-for each % of element split the damage into that many parts and modify them based on target defense for that type.
-add them back together again.
..
Also what do you mean all three? ..All of them?
