Breath Weapon (Su): A cobalt dragon has one type of breath weapon, a line of pulsing magnetic energy. Creatures within the area take force damage (Reflex half). Additionally, creatures within the area are considered bullrushed by the dragon (with a check result equal to the damage dealt). A cobalt dragon has immunity to the breath weapons of other cobalt dragons.

Metalsense (Ex): all ferrous dragons can sense the location and amount of any non-precious metal (precious metals include adamantine, copper, gold, mithral, platinum, and silver) within a distance of 30 feet x the dragon's age category. This makes it nearly impossible to sneak on a ferrous dragon when wearing armor or wielding weapons made of iron or other non-precious metals. Like blindsense, opponents the dragon can't actually see still have total concealment against the dragon.

Spell-like Abilities: 3/day - entangle.

Water Breathing (Ex): A cobalt dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged.

Skills: Craft (trapmaking), Hide, and Jump are considered class skills for cobalt dragons.
