or did they clarify it better somewhere that I did not see?
Add in this for monsters with resisting spells.
The skill Resisting Spells, sometimes referred to as Magic Resist, gives you some basic resistances (physical, fire, cold, poison, energy), even when you are not wearing any armor at all. The formula to calculate your basic resistances is (Resist skill – 40) / 3 * 2 rounded down to the nearest whole number. At 100 skill points, this gives you 40 points in all five resistances, at 120 skill points it gives 44 points in all five resistances.

Looks like 50% but I don't know if the magic resist value is an invisible add on.
