Gold Sense
Dt 3pt
Occasionally dwarves are taught how to hone their sense of smell to detect gems, gold, or other precious metals. A successful Perception test will reveal the direction, if not the location, of these valuables.

A sack of gold in the same room, Ob 1.
A clump of gold ore in an exhausted mine. Ob 3.
One gold coin in a field, Ob 4.
A purse of gold in a crowd, Ob 5.
A cut diamond in an urn full of ash, Ob 9.

+1 Ob for an opposing strong smell, like waste or the sea.
+1 Ob if it is beyond a door or thin wall.
+2 Ob if the gold is more than 50 paces away.
-1 Ob for an exorbitant quantity.
