I posted in another thread,but I think I should re-post it here.regarding to the resistance cap,I think maybe spiderweb's games can offer some insight.for example,the chest amor offers 20% resisance, then legs 20%,but in stead of being caculated as 20%+20%,it counts as 20%+(1-20%)*20%,and so on,if your hand gear has 20%,it's 20%+(1-20%)*20%+(1-20%-(1-20%)*20%)*20%.so without potions or temporary boosts,you'll never be able to reach 100% by equipments alone.
