I find out each equipment item (Cuirass, Belt, Gauntlets, Leggings) give the same value in % resistance. So a Cuirass with Melee Armour Rating +1 give as many % resistance as Leggings (or a Belt or ...) with Melee Armour Rating +1 . But not sur if all kind of Resistances (Melee/Ranged/Magic) has the same values. Also the value of your stats (Strength/Dexerity and intelligence) influences the number in % of the Resistances. On this moment it still confused me hahaha

I think it's all about percentages. But how? I'm searching .... :hihi:
(in Divine Divinity I've find formula's to use in an Excel file making my hero's stats & equipment & more ... . To know, I love mathematics delight !)
