Your Damage Proficiency (shortened to “Proficiency” on cards and in the “Active Weapons” section of your character sheet) reflects how skilled you are at wielding a weapon. You start at 1 Damage Proficiency and, over the course of a campaign, increase this value up to a maximum of 6. Your Damage Proficiency generally determines how many damage dice you roll on a successful attack with a weapon, though other abilities or spells may use Damage Proficiency as well. This value is not weapon-specific, and does not change or reset when you equip a new weapon.

Your permanent proficiency has a maximum of 6. It can temporarily increase above that because of effects such as a spell or ability, but it can’t ever be permanently increased above 6.
