Flexible arms
Help File
These skills represent your proficiency with various types of weapons. Each class has different maximum proficiencies with different types of arms, i.e. the best choice for mages are 'short blades', while a cleric's best choice is with 'bludgeons.'
Proficiency of less than 50% with a given weapon type means that damage inflicted is less than "average", while proficiency greater than 50% increases your damage per hit.
These skills are automatic: you need not type anything to invoke them.
"Pugilism" affects your proficiency with otherwise unclassified weapons.
Percentage in weapon types will not begin to increase until you reach level six.
