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 nonprecious metals. Like blindsense, opponents the dragon can't actually see still have total concealment against the dragon.

Spell-like Abilities: 3/day - entangle, minor image, snare , 2/day - plant growth.

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.
