Weapon Proficiency

Weapon Proficiency is gained by killing mobs in Sword Art Online: Integral Factor. It is being used to unlock new skills for weapons and to increase some of the basic attributes of the character. Every new proficiency level in any weapon gives 1 Attack point - except for the Shield, which provides 1 Defense point per proficiency level.

Each weapon type has their own set of proficiency skills. These skills provide additional perks when combating enemies with that specific weapon, improving overall fighting experience, but also some skills improve some attributes no matter what weapon is being used at the moment.

Assist Characters can learn most of the Weapon Proficiency skills intended for their weapon, excluding Basic Stance and Battle Instinct. For example, Kirito can learn 1H Sword skills by interacting with him.
