The Mastery system is accessed through the Integrated System Box located in your inventory. This system allows players to gain weapon proficiency and unlock bonuses by actively using a weapon.
A weapon must be equipped in order to begin gaining proficiency. Proficiency is earned by defeating monsters while the weapon is equipped.
Each Mastery stage requires a specific amount of proficiency to advance to the next stage. As stages increase additional bonuses are unlocked for the equipped weapon.
There are a total of five stages available to fully complete a weapon Mastery.
Proficiency Boosters can be purchased directly from the Mastery menu. These boosters are required in order to gain proficiency.
Players may toggle the proficiency message to view how much proficiency is gained per defeated monster.
