Dragon Compendium Vol. 1
Breath Weapon (Su): An orange dragon's breath weapon is a bizarre mixture of oily saliva and a deadly, explosive compound. When this compound is exposed to water or air, it detonates in a ferocious explosion. The dragon's oily saliva shields this mixture, but it quickly evaporates. Once it is gone, the compound explodes.
The orange dragon breathes this mixture in a line. Any creature caught in this area is covered with its sticky, gooey breath. A successful save allows a creature to avoid becoming covered in the dragon's breath weapon.
After 2 rounds, the mixture explodes in a 10-foot burst centered on each creature. The target creature takes full damage, with no saving throw, while all other creatures in the explosion's area save as normal for half damage. A creature takes damage from this breath weapon only once per detonation. A creature standing between two allies covered with the dragon's spew makes only one save and takes damage once, not once for each explosion. The two creatures covered by the breath weapon also take damage only once. They do not suffer damage from the blast centered on the other victim. An orange dragon's breath weapon recharges slower than that of other dragons. An orange dragon can use its breath weapon once every 1d6 rounds.
Poison Immunity (Ex): Orange dragons subsist on a wide variety of poisonous animals and plants in their jungle homes. They develop a natural immunity to poisons of all type.
Water Breathing (Ex): An orange dragon can breathe water as easily as air. It can use its spells, breath weapon, and other abilities underwater without restriction.
Spell-Like Abilities: 3/day - pass without trace, control water ; heat metal; 1/day - suggestion, hallucinatory terrain.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Water. Creatures with the water subtype always have swim speeds and can move in water without making Swim checks. A water creature can breathe underwater and usually can breathe air as well.
