Chapter 1 - Non-weapon Proficiencies
Stonemasonry Non-weapon Proficiency
A stonemason is able to build structures from stone so that they last many years. He can do simple stone carvings, such as lettering, columns, and flourishes. The stone can be mortared, carefully fitted without mortar, or loosely fitted and chinked with rocks and earth. A stonemason equipped with his tools (hammers, chisels, wedges, block and tackle) can build a plain section of wall one foot thick, ten feet long, and five feet high in one day, provided the stone has already been cut. A stonemason can also supervise the work of unskilled laborers to quarry stone; one stonemason is needed for every five laborers.
Dwarves are among the most accomplished stonemasons in the world; they receive a +2 bonus when using this skill.
