A silver dragon can assume any animal or humanoid form 3/day as if using polymorph.
A very young or older silver dragon can tread on clouds or fog as though on solid ground.
An old or older silver dragon is surrounded by an aura of cold. All creatures within 5 feet of the dragon take 1d6 points of cold damage at the beginning of the dragon’s turn. An ancient dragon’s aura extends to 10 feet. A great wyrm’s aura damage increases to 2d6. A silver dragon can suppress or activate this aura at will as a free action.
A juvenile or older silver dragon can see perfectly well in fog and clouds.
A young or older silver dragon’s aerial maneuverability is one step better than normal.
Instead of a cone of cold, a silver dragon can breathe a cone of paralyzing gas. Creatures within the cone must succeed on a Fortitude save (DC 29) or be paralyzed for 1d6 rounds plus 1 round per age category of the dragon.
Any spell that targets an ancient or older silver dragon but fails to penetrate the silver dragon’s spell resistance might be reflected. If the caster level check to penetrate the dragon’s spell resistance is failed by 5 or more, the spell is reflected. If the check fails by 4 or less, the spell is merely wasted. This otherwise functions as spell turning.
