Homebrew Half-Dragon Species Details

Half-Dragon

(Human)

When a dragon in polymorphed form mates with another creature, the union sometimes produces half-dragon offspring. A creature might also transform into a half-dragon as a result of a mad wizard’s spell or a ritual bath in dragon’s blood. In all these cases, the result is a creature that combines the essence of a dragon with the form of its original race. Regardless of their origins, all half-dragons have similar features and appearance, gaining special senses, resistance to destructive energy, and a breath weapon.

Draconic Nature. Half-dragons are incapable of having natural born offspring. Those that wish to propagate must find other ways to do so, almost always involving magic. By way of compensation, half-dragons are blessed with long life. Barring unforeseen misfortune, a typical half-dragon’s life expectancy is twice that of its nondraconic line, so that a half-dragon human might live more than a century and a half.

Half-dragons inherit personality traits common to their draconic heritage, so that half-gold dragons are often shy and secretive, while half-copper dragons are impish and playful. Half-green dragons are deceitful, while half-white dragons are often dim-witted brutes. These traits are tempered by a half-dragon’s other lineage, but greed, arrogance, and paranoia are qualities that even good-aligned half-dragons often possess.

Breath Weapon

You can use your action to exhale destructive energy. Your draconic ancestry determines the size, shape, and damage type of the exhalation. When you use your breath weapon, each creature in the area of the exhalation must make a saving throw, the type of which is determined by your draconic ancestry. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. After you use your breath weapon, you can’t use it again until you complete a short or long rest.

Damage Resistance

You have resistance to the damage type associated with your draconic ancestry.
