This massive reptile resembles nothing more than a towering mountain of rock, but its eyes gleam with intelligence that belies its brute force.
Earth Mastery (Ex): An advanced earth drake gains a +1 bonus on attack and damage rolls if both it and its foe are touching the ground. If an opponent is airborne or waterborne, the drake takes a –4 penalty on attack and damage rolls. (These modifiers are not included in the statistics block.)
Tremor (Su): Once per day, an advanced earth drake can cause a tremor at a point where it touches the ground. All creatures standing on the ground within 60 feet of the drake must make a Reflex DC 22 save or fall down. Airborne or waterborne creatures don’t suffer any ill effects, and the tremor doesn’t deal any structural damage.
Skills: Earth drakes have a +4 racial bonus on Hide checks. They have an additional +4 racial bonus on Hide checks when in rocky environments (such as mountain terrain or underground).
