Armor negating and penetrating?

[MaxWilson]

Almost. With magical attacks resistances come into play. I believe it's

damage = R*(2d6oe + magical base damage) - 2d6oe - (protection * X)

X = 1, 1/2 if AP, 0 if AN
R = 1, 0.5 if 50% resistant, 2 if 100% vulnerable, etc.

I'm not entirely positive about this (R may not apply to the 2d6oe term), and you can check it in the debug log if you want. Anyway, this means that 50% resistance will probably cut your damage by more than 50%.
