This is a note I found in a UOHoC chat that explains this feature.
Glamdring> *Nova_* What logic do you follow with regards to parrying as a valid defense against magical attacks? Personally I myself feel that it should have some effect on missle-like attacks such as fireball, magic missle, and energy bolt as they are generally pure forms of energy directed at an individual. It does not have to block them entirely but at least absorb some damage.
