what is affinity mhw

Affinity is a statistic that helps determine how much chance a weapon has to deal additional damage in Monster Hunter World. It is also known as Critical Chance. Affinity can be positive or negative, meaning that a weapon with negative affinity will actually be more likely to do weak hits that have reduced damage. Meanwhile, a weapon with a high affinity stat will have a higher chance to do an extremely damaging critical hit. Attack Boost, Critical Eye, Critical Draw, and Affinity Sliding are some of the Armor Skills that can increase Affinity. At 0% Affinity, there is no chance for a bonus or penalty to damage.
