Weapon mastery

From GuildWiki

The term weapon mastery (more commonly weapon mastery attributes or weapon masteries) is used to refer the subset of weapon attributes that follow the naming pattern of (weapon name) Mastery: Axe Mastery, Hammer Mastery, Dagger Mastery, Scythe Mastery and Spear Mastery, as well as Swordsmanship and Marksmanship, which follow the same mechanics. Each point in one of the aforementioned attributes increases your critical hit chance and damage while wielding a weapon of that type. Beast Mastery similarly affects the damage a pet deals. Some weapons also require a certain attribute level to be met to deal the damage value shown when selecting it. Additionally, Dagger Mastery affects the chance to execute a double strike.
