Stability: Duergar are exceptionally stable on their feet. A duergar receives a +4 bonus on ability checks made to resist being bull rushed or tripped when standing on the ground (but not when climbing, flying, riding or otherwise not standing firmly on the ground). Duergar can move at full speed even when wearing medium or heavy armor or when carrying a medium or heavy load (unlike other creatures, whose speed is reduced in such situations)
Stonecunning: This ability grants a duergar a +2 racial bonus on Search checks to notice unusual stonework, such as sliding walls, stonework, traps, new construction (even when built to match the old), unsafe stone surfaces, shaky stone ceilings, and the like. Something that isn’t stone but that is disguised as stone also counts as unusual stonework. A gray dwarf who merely comes within 10 feet of unusual stonework can make a Search check as if he were actively searching, and a duergar can use the Search skill to find stonework traps as a rogue can. A duergar can also intuit depth, sensing his approximate depth underground as naturally as a human can sense which way is up. Duergar have a sixth sense about stonework, an innate ability that they get plenty of opportunity to practice and hone in their underground homes.
