Stone Mason

• This proficiency is a "Trained Use" skill, meaning that it cannot be used until it is unlocked.
• The cost to unlock this skill is One Proficiency Point.
• The Attribute Modifier for this skill is Strength.

A character with this proficiency unlocked is able to build structures from stone in such a fashion that they last for many years. The stones are often, but not always, mortared together. A stonemason is thus able to construct, or aid in the construction of, stone buildings, walls, towers, and other such fortresses.
Optional: If the character wishes to take the risk, they can make a proficiency check at the end of their construction. If the check is successful, the structure will gain a small bonus in structure defense. If it fails, the structure instead receives a penalty in structure defense, and requires an additional week to reinforce.
