Special Abilities
A charda's body seethes with freezing black bile. Its supernaturally cold, black bile is the source of the additional cold damage when a charda bites a creature. As a standard action, a charda can expel its full store of bile as a breath weapon that can take the form of a 60-foot line or a 30-foot cone. All creatures in this area take 8d6 points of cold damage (DC 18 Reflex half). A charda can use this breath weapon once every 1d4 rounds—while its black bile is recharging, it does not deal additional cold damage with its bite. The save DC is Constitution-based.Cold Vigor
When a charda is in a cold environment, it becomes more animated and gains a +1 racial bonus on attack rolls and weapon damage rolls. A charda gains a +8 racial bonus on bull rush and trip attacks.
