Weapon Proficiency

Definition

Weapon proficiency is a rule about who may use which weapons well. A character is trained in some weapons and not others, or builds skill in a weapon type by using it, and a weapon outside that training hits less often, strikes fewer times, or loses its features. It is a rule with delivery any, covering melee, missile and thrown weapons alike. Class and advancement systems (variable player powers, subclasses, experience levels) contain it. Two-handed and reach are properties printed on a weapon, where proficiency belongs to the wielder.

How it works

The player chooses weapons from what the class allows. In the Players Handbook each class begins with a number of weapons, a cleric with two, and adds one at set level intervals; any other weapon takes a penalty to hit, from -2 for fighters to -5 for magic-users. The 3rd edition recasts proficiency as feats over simple, martial and exotic weapons and fixes the penalty at -4. Baldur’s Gate 3 turns the penalty into a missing bonus: a proficient attack adds the proficiency bonus, +2 at first, and an unproficient one lacks it and cannot use the weapon’s weapon actions. The decision is whether to wield the best weapon found or a trained one. Final Fantasy II’s manual warns that a stronger axe given to a sword-trained character attacks with few hits and poor accuracy.

Variations

• Counted proficiencies (Players Handbook): a number of chosen weapons that grows with level.
• Weapon groups (Dungeons & Dragons, 3rd edition; Baldur’s Gate 3): proficiency granted for a group or a single weapon by class, race and feats.
• Training by use (Final Fantasy II): a level per weapon type, raised by points earned in battle with that type.
• Weapon ranks (Fire Emblem: The Blazing Blade): ranks E to S raised by use, gating which weapons a unit may wield, inside classes confined to their weapon types.
• Features behind proficiency (Baldur’s Gate 3): weapon actions open only to a proficient wielder.

Limits

The rule adds no limit of its own: it changes how well a weapon works, not how often it can be used. Each example carries its host’s limits. The tabletop examples spend an action, the Players Handbook giving missile weapons a rate of fire per round, and Baldur’s Gate 3’s weapon actions mostly take an action and recover on a short rest. Final Fantasy II’s attack is a battle command. Fire Emblem’s weapons carry a count of uses, so a rank opens weapons that also wear out.

History and provenance

The earliest documented use cited is the Players Handbook (1978). Dungeons & Dragons (1974) is an antecedent that restricts rather than penalises, arming magic-users with daggers only and clerics with non-edged magic weapons, as Tunnels & Trolls (1975) also limits magic-users. RuneQuest, released in July 1978, gave attack and parry chances with a character’s usual weapons; the Handbook’s release month is disputed, so the order is open. Final Fantasy II (1988) brought training by use into a video role-playing game. Fire Emblem’s first game (1990) already barred a unit from items above its weapon level, and The Blazing Blade (2003) ranked weapon use E to S. The 3rd edition (2000) recast proficiency as feats, and Baldur’s Gate 3 (2023) carries the rule into video.

Notable examples

Provenance

Earliest documented use: Advanced Dungeons & Dragons, Players Handbook (1978), tabletop rpg. Confidence: low. The earliest documented use cited is the Players Handbook (1978), whose Weapon Proficiency section limits each class to a number of weapons, adds more as the character rises in level, and sets a to-hit penalty for any other weapon. RuneQuest, of the same year, gave attack and parry chances with a character's usual weapons, as Steve Perrin's conversion article of September 1978 shows. Chaosium's catalogue dates RuneQuest's release to Origins, 14 to 16 July 1978; the Handbook's foreword is dated 2 June 1978, and its first printing is reported as June by some accounts and August by a collectors' listing, so the order between the two is open. Dungeons & Dragons (1974) is an antecedent that restricts rather than penalises: magic-users may arm themselves with daggers only, and clerics with non-edged magic weapons. Tunnels & Trolls (1975) likewise limits magic-users to daggers and other one-die weapons, and Empire of the Petal Throne (1975) bars priests from edged weapons. Other role-playing games of 1975 to 1977 remain unsurveyed, which keeps confidence low.

Established form: Advanced Dungeons & Dragons, Players Handbook (1978), tabletop rpg. The earliest documented use also set the form. Confidence: low. The form of a per-weapon proficiency with a penalty outside it continues through the Dungeons & Dragons line, in the 3rd edition's proficiency feats and -4 penalty and in Baldur's Gate 3's proficiency bonus, which an unproficient attack lacks. The line runs within one game family and its licensed adaptation, so confidence is low; no source cited traces Final Fantasy II's or Fire Emblem's use-trained levels to it.
