This article contains an error. In the "Calculations" section, under "Percentage magic resistance reduction", the second point says that "Percentage magic resistance reduction can reduce a target's resistance below zero—if stacked beyond 100%—however, it's currently not possible since the greatest amount of percent magic reduction is 55%". This is mathematically impossible, since it stacks multiplicatively. Multiplicative stacking means that it won't even reach 100%. In fact, multiplicative stacking has diminishing returns. The more is stacked, the less each item contributes.
