Description

Rainbow dragons are unpredictable, carefree, wandering chromatic dragons. They are able to adapt to most environments; as a result, they never truly settle in one lair, making them hard to track. Other dragons prefer to avoid this subspecies due to their wild nature.

These dragons are known for their widely varying personality; they're probably the most emotive and individually unique dragons to be found. Their chaotic breath weapon can grant an array of disastrous effects to anyone caught in the blast.
