Draconic Creature - Half-Dragon

Half-dragons are fictional creatures in the Dungeons & Dragons fantasy roleplaying game.

A dragon's magical nature allows it to breed with virtually any species. This sort of conception usually happens when a dragon has been polymorphed or had its form changed in some way. Metallic half-dragons are usually kind except when abused by the common races in the game which will turn half-dragons away from all others except from its kin; those based on evil chromatic dragons often mirror their progenitor's outlook. Half-dragon's features are reptilian, with scales, horns, elongated faces and exaggerated teeth and claws. All have wings.

When engaged in combat half-dragons are formidable creatures and can be nearly invulnerable to weak adventurers. All Half-Dragons have a breath weapon according to their variety. Gold, Red and Brass spew fire. Bronze and Blue breathe lightning. Black, Green and Copper exhale acid and corrosive gas. Silver and White dragons blow extremely frigid air and ice. In addition all half-dragons have a special immunity towards the element of their breath weapon. There are exceptions to this for different dragon types. For example, the Deep Dragon of the Forgotten Realms setting has a Corrosive Acid gas breath weapon, but has a Charm immunity rather than an acid immunity.

The accessory, Races of the Dragon, has information on playing a half-dragon character, making half-dragons based on other dragon types (such as the dragons of the Oriental Adventures or Forgotten Realms campaign settings or the planar dragons of the Draconomicon), and creating draconic creatures (which have some amount of dragon blood in their family, but not a dragon parent).
