Proficiency

Your Proficiency reflects how skilled you are at wielding weapons. You start at 1 Proficiency and can increase this value to a maximum of 6 over the course of a campaign. Your Proficiency determines how many damage dice you roll on a successful attack with a weapon, though other abilities or spells use Proficiency as well. This value is not weapon-specific, and does not change or reset when you equip a new weapon.

Tip: The effects of a spell or an ability might allow you to increase your Proficiency beyond the maximum of 6.
