increase the chance to escape suffering the effect each time the player may potentially receive it, while others grant complete immunity. However, sometimes the equipment that is resisting an effect, will in exchange, as a penalty, increase vulnerability against a different effect, offering the player the opportunity to make tactical choices. Buffs and debuffs In many MMORPGs, the terms buff and debuff are commonly used to describe status effects. Some spells or powers may debuff an enemy while buffing an ally at the same time. Buffs Buff is the term generically used to describe a positive status effect that affects mainly player or enemy statistics (usually cast as a spell).

In addition to their normally very high stats, many heroes also have auras which confer beneficial status effects or attribute bonuses to any friendly units that enter within a certain radius of the hero. This makes the hero unit an important factor in an engagement as, in addition to
