Silence (Sp): The dragon can use this ability as the spell of the same name, a number of times per day equal to its age category.

Other Spell-like Abilities: 3/day - create/destroy water, improved invisibility, and wind wall; 1/day - wall of stone and enervation.

Air Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane Air. Air creatures always have fly speeds and usually have perfect maneuverability (see the section on Movement).

Water Subtype

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.
