Weaponcrafters are artificers who make armour and weapons. The craft is highly respected, especially by the nobility and warrior classes it primarily serves. Learning the skills and knowledge of weaponcrafting takes several years of study under a master. The Weaponcrafters' Guild has a monopoly on the design, manufacture, and sale of weapons and armour in most areas of western Lythia. Some master weaponcrafters maintain a franchise in a town, while others are bonded to a noble household, fighting order, or a franchised master. Although a master weaponcrafter can usually produce a variety of weapons and armour types, some choose to specialize in making a specific class of weapons, such as bows or swords, while others focus on making armour or shields.

This article describes the organization and activities of the Weaponcrafters' Guild as well the guild's place in Hârnic society. Details are given for each of the five primary guild disciplines: armourer, bowyer/fletcher, shieldmaker, swordsmith, and weaponsmith. HârnMaster-compatible rules are given for crafting and enhancing weapons and armour.
