Breath Weapon (Su): A chromium dragon has two types of breath weapon, a line of solid ice (cold) and a cone of freezing crystals. Creatures within a cone of freezing crystals take 1 point of Dexterity damage per age category of the dragon (Fortitude half).

Spell-Like Abilities: 3/day - pass without trace (ice and snow only); 2/day - ice shape (as stone shape, but applies to ice instead of stone).

Skills: Appraise, Bluff, and Jump are considered class skills for chromium dragons.

Cold Subtype

A creature with the cold subtype has immunity to cold. It has vulnerability to fire, which means it takes half again as much (+50%) damage as normal from fire, regardless of whether a saving throw is allowed, or if the save is a success or failure.
