Breath Weapon (Su): The brown dragon's breath weapon is a line of acid. It does not use this attack against mounted foes, since it knows that horses are good eating. Using a breath weapon is a standard action. Once a dragon breathes, it can't breathe again until 1d4 rounds later. A blast from a breath weapon always starts at the dragon's mouth and extends in a direction of the dragon's choice.
Tremorsense (Ex): Brown dragons can automatically sense the location of anything within 500 feet that is in contact with the ground.
Create Water (Sp): The dragon can use this spell-like ability once per day.
Sandstorm (Sp): Once per day, an adult brown dragon can create a vortex of violently churning sand at a distance up to 80 yards away. All creatures within a 60-foot radius of the center of the sandstorm take 1d6 points of damage each round they remain within the sandstorm. Characters in the swirling sands are blinded and must make a Balance check (DC 15) during each round they move more than 5 feet or fall prone.
Summon Huge Air Elemental (Sp): Once per day, an old brown dragon can cast summon nature's ally VI to summon one Huge air elemental, 1d3 Large air elementals, or 1d4+1 air elementals of smaller size.
Summon Greater Air Elemental (Sp): Once per day, an ancient brown dragon can cast summon nature's ally VIII to summon one greater air elemental, 1d3 Huge air elementals, or 1d4+1 air elementals of smaller size.
Other Spell-Like Abilities: 1/day - create water; disintegrate.
Frightful Presence (Ex): A young adult or older dragon can unsettle foes with its mere presence. The ability takes effect automatically whenever the dragon attacks, charges, or flies overhead. Creatures within a radius of 360 feet are subject to the effect if they have fewer HD than the dragon (39).
A potentially affected creature that succeeds at a Will save (DC 35) remains immune to that dragon's frightful presence for one day. On a failure, creatures with 4 or fewer HD become panicked for 4d6 rounds and those with 5 or more HD become shaken for 4d6 rounds.
Dragons ignore the frightful presence of other dragons.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
