Half-Dragon Template

A beast, humanoid, giant, or monstrosity can become a half-dragon.

Transformation. When a creature becomes a half-dragon, it retains all its statistics except as noted below.

First, the draconic parentage of the half-dragon must be determined:

Type Energy Area
Black, Copper Acid 100-foot line that is 10 feet wide
Blue, Bronze Lightning 100-foot line that is 10 feet wide
Brass,Gold,Red Fire 100-foot line that is 10 feet wide
Green Poison 100-foot line that is 10 feet wide
White, Silver Cold 100-foot line that is 10 feet wide
  • Challenge. To avoid recalculating the creature's challenge rating, apply the template only to a creature that meets the optional prerequisite in the Breath Weapon table below. Otherwise, use the guidelines in the Dungeon Master's Guide to recalculate the rating after you apply the template.

  • Senses. The half-dragon gains blindsight with a radius of 10 feet and darkvision with a radius of 60 feet.

  • Resistances. The half-dragon gains resistance to a type of damage based on its color.
