Alternate Form(Su): A silver dragon can assume any animal or humanoid form of Medium size or smaller as a standard action three times per day. A dragon can remain in its animal or humanoid form until it wishes to assume a new one or return to its natural form. A true seeing spell or ability reveals the creature's natural form. A creature using alternate form reverts to its natural form when killed, but separated body parts retain their shape. A creature cannot use alternate form to take the form of a creature with a template.

Breath Weapon (Su): A silver dragon has two types of breath weapon, a cone of cold (6d8 damage, Reflex save for half DC 18) or a cone of paralyzing gas. Creatures within the latter must succeed at a Fortitude save (DC 18) or be paralyzed for 1d6 rounds plus 3 rounds. Using a breath weapon is a standard action. Once a dragon breathes, it can't breathe again until 1d4 rounds later. If the dragon has more than one type of breath weapon, it still can breathe only once every 1d4 rounds. A blast from a breath weapon always starts at the dragon's mouth and extends in a direction of the dragon's choice.

Cloudwalking (Su): The dragon can tread on clouds or fog as though ground. The ability functions continuously but can be negated or resumed at will.

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).
