Magic resistance is a stat that modifies the amount of magical damage taken by a unit. Magic resistance values can be modified by items, hero abilities and Alliance bonuses. A positive value reduces the amount of magical damage received by a unit, while a negative value increases the magical damage received.
Magic resistance stacks are multiplicative. For example, A unit with 20% magic resistance gaining a bonus of 50% and another one of 50% would result in a 80% total magic resistance.
Magic resistance has no effect on physical damage or pure damage.
