Capsize (Ex)

An old or older brine dragon can attempt to capsize a boat or ship by ramming it as a charge attack and making a CMB check. The DC of this check is 25 or the result of the boat captain’s Profession (sailor) check, whichever is higher. For each size category larger the ship is than the brine dragon’s size, the dragon takes a cumulative –10 penalty on the check.

Desiccating Bite (Su)

An Ancient brine dragon’s bite causes weakness, dealing 1d2 points of Strength drain in addition to its normal damage. A great wyrm’s bite deals 1d4 points of Strength drain. A Fortitude save (DC equals the Dragon’s breath weapon save DC) negates the Strength drain.

Painful Strikes (Su)

A great wyrm brine dragon’s natural attacks are so laden with salt and acidic crystals that every time it strikes a creature with one of these attacks, the target must make a Fortitude save (DC equals the dragon’s breath weapon save DC) or be stunned for a round from the pain.


Environment any aquatic (Plane of Water)
Organization solitary
Treasure triple

Although not inherently evil, brine dragons have little patience for kindness and philanthropy. As they age, they grow more and more opinionated and obsessed with power—by adult age, a brine dragon counts itself a failure if it doesn’t rule over a collection of “lesser beings” such as humans, merfolk, locathah, or even sahuagin.
