Blue Mountain
Stonecraft
A character with this skill is able to fashion items from stone. The item may be as simple as a stone block for a wall or as complex as an intricate stone statue of an armoured warrior. He also has a chance of automatically noticing stonework traps such as falling blocks, pit traps, etc., as well as secret doors concealed in stone walls.

A character can also do general stonework (bonus of ((DEX - 15) x 3) + (rank x 5)).
