Monster Hunter World: Affinity Booster explained

While some monsters in Monster Hunter World can be hard to beat, specialized tools like the Affinity Booster make the grind easier—except that the tool itself can be a bit tricky to unlock. Don’t worry, however, as everything you need to know about the Affinity Booster is in this guide.

What is the Affinity Booster in Monster Hunter World? 

As the name suggests, Affinity Booster is a tool you can procure in Monster Hunter World to boost the affinity of your weapon. It’s not just you who gets its perks, however, your allies can also benefit from its red cloud of smoke when deployed.

Affinity Booster works like the Health and Cleanser Boosters, which boosts your health and cleanses you of any status effects or ailments, respectively—but it boosts your affinity instead. You and your allies get an affinity boost of 50 percent when you enter the Affinity Booster’s area of effect. The buff adds to your weapon’s current affinity percentage for a maximum of 100 percent.

The affinity-boosting cloud lasts for a total of 60 seconds when deployed, but the buff lasts for 20 seconds. You can leave the cloud when charged and re-enter it when the effect needs to be recharged.

For those unaware, affinity is a weapon characteristic that gives you an idea of the weapon’s potential to deal a bonus or penalty to the damage you deal. Positive affinity means the weapon’s attack can deal a critical hit (+25 percent physical damage), while negative affinity denotes the possibility of a blunder (-25 percent physical damage). Weapons in Monster Hunter World naturally flaunt some affinity, but you can boost base affinity by adding a skill or using the Affinity Booster.
