Physical and magical resistance?

How is it calculated? How much of a difference would 18k phy and spell resistance make over 14k for example

Should be roughly 8% difference between the two. It scales up or down based on your current penetration and the resistances of the target. So it should be essentially:

(penetration gained/lost) / (50000 - 18200 + current penetration)

This would give you:

-4000/(50000-18200+18000) = -0.0803

Which would be interpreted as an 8% loss. I got this formula from @SodanTok , my testing on the xbox yielded damage results in agreement with that formula.
