Gauld
Gauld is a non-magical, alchemical compound that when applied to clothes (and other worn items, such as leather armor, boots, vambraces, etc.) vastly increases their toughness and resistance to attack as well as durability while still retaining most of their flexibility in the case of clothing. The treatment process is called gaulding. The ability of an enemy or monster to cut or pierce clothing so treated is drastically reduced, though trauma from the force of the attack is still transmitted through the fabric. For example, a well-made greatcoat is able to repel a direct hit by a musket ball, though the force of the shot is still felt by the wearer. When newly treated garments or armor have a faint scent similar to wood varnish. Master Gaulders in large cities deliberately perfume their gaulding with other pleasant scents to overcome buyer reticence.
