Breath Weapon (Su): Mist dragons have two types of breath weapons: a cone of scalding steam that deals fire damage and a line of caustic slime. Creatures struck by slime must make Fortitude saves or be sickened for 1d6 rounds plus 1 round per age category of the dragon.
Mist Form (Su): At will as a standard action, a mist dragon can assume a misty form. This power works just like a gaseous form spell cast by a character of the dragon's age category or caster level (whichever is higher), except as follows: The dragon loses its natural armor bonus, but gains a deflection bonus to AC equal to twice its age category. While in mist form the dragon is indistinguishable from mist or fog and gains total concealment when in any kind of natural or magical fog or mist. The dragon gains damage reduction 10/magic, or, if the dragon is old enough to have damage reduction already, its damage reduction increases by 10 points. The dragon can fly at half its normal flying speed, with perfect maneuverability. The dragon cannot use its natural weaponry or breath weapon, but it can use its spell-like abilities and spells. The dragon can dismiss the effect as a standard action.
Spell-Like Abilities: 3/day -- fog cloud, gust of wind, sleet storm, wind wall; 1/day -- control water, control weather, solid fog.
Skills: These skills are available to mist dragons at 1 skill point per rank: Bluff, Sense Motive, Swim, and Survival. These are in addition to the skills noted in the dragon entry on the Monster Manual.
