Yellow dragon

Yellow dragons were dragons that were found in the deserts Toril. A very rare species of chromatic dragons, only a few individuals of this species had been spotted throughout history.

Description
Yellow dragons grew up to 116 feet (35 meters) in length, smaller than a brass dragon. They were born with soft, tan-colored scales. As they aged, the scales became harder and lighter in color, turning a yellow-grey color by adulthood. Their claws, scales and teeth all blend into the desert background, giving the yellow dragon amazing camouflage abilities.

Combat
Yellow dragons preferred ambush attacks over direct attacks. They were fierce fighters. During combat they will use spells and their innate abilities to mislead and confuse their opponents. A common abush tactic, a yellow dragon will bury itself at the bottom of a steep, cone-shaped depression it dug in the sand. When prey or an opponent walks into the depression, the dragon would begin moving its wings below the sand, causing the walls to collapse. The target would be trapped and usually fell right into the dragons mouth.

The yellow dragon's breath weapon was a high-speed blast of super-heated air and sand. It covered an area of 50 feet (15 meters) in length, 40 feet (12 meters) in width and 20 feet (6 meters) in height.

Brass dragons were the primary enemy of a yellow dragon.

Abilities
A yellow dragon had innate magical abilities, each gained as they grew older. They were immune to fire and heat. They could cast at will Silence, 15' radius. Three times per day a mature yellow dragon could use create or destroy water, dust devil, enervation and wind wall. Twice a day a mature yellow dragon could use improved invisibility.

Society
Yellow dragons were solitary and secretive who formed no bonds with any creature, including other yellow dragons. Highly territorial, the only time they tolerated the presence of another yellow dragon was for mating. Mates did not live together. A mother raised their offspring but would not protect them from attackers. Offspring separate from their mothers as juveniles.

Ecology
Yellow dragons lived deep in the deserts of Toril, such as the Anauroch. They preferred sandy, windswept desert plains to make their home. They can comfortably tolerate the extreme heats of the deep desert, and can survive the subfreezing nighttime temperatures. They usually shared the same territory as brass dragon. The diet of a yellow dragon consists of fresh meat, although they would eat anything including plants if needed. They considered the eggs of brass dragons and humanoids, such as humans or elves, as a delicacy.
