Air Breathing (Ex)

The river dragon can breathe air just as naturally as water. This dragon can freely use its breath weapon, spells and other abilities in both air and water.

Boiling Aura (Su)

This river dragon radiates heat causing any water around it to boil. All creatures within 10 ft. of the dragon take 2d6 points of fire damage at the beginning of the dragon’s turn. The river dragon can suppress or activate this ability at will as a free action.

Geyser (Su)

The river dragon can call forth a powerful geyser from the ground as a standard action. The geyser is 10 ft. wide burst within 400 ft. of the river dragon. All creatures standing in the geyser’s space takes 4d6 points of fire damage per round from the scalding hot water and are distracted. All other creatures within 200 ft. of the geyser take 2d6 points of fire damage per round in addition to the normal rain penalties.

Speak with Aquatic (Ex)

This river dragon has a constant spell-like ability to speak with animals of the aquatic subtype. This otherwise functions as speak with animals.

Spit (Ex)

This river dragon has the ability to spit water at any target within 60 ft. as a ranged overrun attempt. The CMB check for the spit is the river dragon’s CMB but is one size category smaller than the river dragon and gains the benefits of the Improved Overrun feat. This does not grant the river dragon the benefits of the Improved Overrun feat when making a overrun attempt and not spitting.

Watersight (Ex)

This river dragon can see underwater four times better than a human.


Environment temperate aquatic
Organization solitary
Treasure triple

The river dragon is a ferocious dragon commonly found in the canals, rivers and water ways of the River Nations. This finned dragon swims with a subtle grace that belies its size. It moves on land similar to a snake and is just as dangerous out of water is it is in. The river dragon scalds its enemies with river water super heated with its breath before devouring them.
