Half-Dragon, Faerûnian
Monster Compendium Monsters of Faerûn details five varieties of dragon common to the lands of Faerûn: brown, deep, fang, shadow, and song dragons. Like the dragons described in the Monster Manual, these dragons sometimes crossbreed with other creatures, producing half-dragons. Deep dragons and song dragons are fond of spending time in humanoid form, so half-dragons of these ancestries are especially common. Such an offspring uses the half-dragon template, with certain adjustments based on the type of its dragon parent.
Speed: Half-brown dragons never have functional wings, regardless of their size.
Damage: Half-fang dragons deal damage with their bite and claw attacks as if they were one size category larger than they actually are.
Special Attacks: A half-dragon of brown, deep, shadow, or song dragon ancestry gains a breath weapon usable once per day, as given on the table below.
| Dragon Variety | Breath Weapon | Damage (DC) |
| Brown | Line* of acid | 6d6 (19) |
| Deep | Cone** of flesh-corrosive gas | 6d8 (18) |
| Shadow | Cone of shadows | 1d2 negative levels (18) |
| Song | Cone of electrically | 6d6 (17) charged gas |
| *A line is always 5 ft. high, 5 ft. wide, and 60 ft. long. **A cone is always 30 ft. long. | ||
Three times per day, a fang half-dragon can choose to deal 1d4 points of Constitution drain with its bite attack (Fort save DC 14 negates).
Special Qualities: Half-dragons also have additional immunities or resistances based on their dragon variety.
| Dragon Variety | Immunity or Resistance |
| Brown | Acid immunity |
| Deep | Charm immunity, cold and fire resistance 10 |
