Cobalt Dragon (Dungeons & Dragons) Wiki.png Alternate Name: Alignment Traits Size Habitat Breath Weapon Treasure The Cobalt Dragon (Dungeons & Dragons) is a type of dragon in the Dungeons & Dragons universe. It is a metallic dragon. Grim and sullen in demeanor, the fierce cobalt dragons measure success by the territories they rule and the lesser creatures they subjugate. They suffer no traveler to pass through their lands without bending knee and acknowledging their power, and anyone who refuses quickly comes to regret that error. Most cobalts rule over barbaric tribes or small, remote settlements, exacting instant obedience through claw, fang, and icy breath.
