Dexterity adds dodge, strength adds 'armour', Int adds resistance, Vit adds health.
Is that confirmed that Armour is essentially all res and etc? I'd be more than happy to add it in if that were the case, it's just it is the first I have heard of it that's all Makes sense, somewhat.
Edit: Just read on a random post elsewhere for 'research' for an argument here on another thread and yes, Strength does somewhat seem to be equal to Armour. I'll consider sticking that in as a desirable mod.
