Homebrew Elf Demi-Dragon Species Details

Demi-Dragon

Some sorcerers are born with a spark. Others are burned by it and crawl back changed.
Demi-dragons are those who underwent a forced or chosen metamorphosis—warped by dragon’s blood, arcane rites, or unstable magic. Their bodies twist with scales and fangs, their veins pulse with stolen power, and a volatile spark kindles within them—an echo of true draconic might. They are neither fully dragon nor fully mortal, but something in between. Each must forge their path through fear, isolation, and obsession—some embracing the monster they’ve become, others striving to master it.

Imitation of Form

To some, dragons are gods. To others, they are tools. For the demi-dragon, they are a blueprint etched into the soul.
Dragons are feared, revered, and mythologized for their might—but for certain individuals, they represent something more. A promise. A temptation. A dare. Some seek to emulate dragons through zealotry, pledging their lives and bodies to ancient powers in hopes of transcending their mortal limits. Others, twisted by ambition, see dragonhood as something to seize. Whether driven by reverence, greed, desperation, or sacrifice, these individuals undergo a ritual transformation—an arcane rewriting of their very biology. In some cases, it’s willing. In others, it’s not. Regardless, they emerge as demi-dragons: beings made rather than born, imperfect mirrors of draconic power, bearing the mark of creation rather than lineage.

Ritual Transformation

There is no single path to become a demi-dragon—only pain, change, and the unknown.
The process by which one becomes a demi-dragon is mysterious and inconsistent, and likely by design. Arcane secrets, lost rituals, experimental alchemy, and ancient draconic rites all serve as gateways to this transformation. Whether achieved by surviving a plunge into molten dragon’s blood, enduring the bite of a cursed wyrm, or submitting to the sigils of forgotten cults, the transformation always draws upon the essence of a true dragon. It forces that essence into a mortal vessel, imbuing the subject with partial traits—scales, claws, draconic eyes, or elemental breath. But the change is rarely complete at first. Many emerge wingless, patchy, or only half-transformed. These flaws sometimes correct over time, with magic and growth… but some never do. There is no known way to reverse the transformation once begun.

Spark of Magic

It starts with a flicker. Then a burn. Then a hunger that never leaves.
At the heart of every demi-dragon is a spark—a living shard of draconic power lodged deep within their being. It’s this spark that fuels their abilities, mimicking the breath of dragons and awakening elemental forces. But it is not self-sustaining. A demi-dragon must feed this inner fire. Unlike sorcerers of inherited bloodlines, their magic is unstable—needing to siphon power from outside sources. They may draw on magical objects, ambient ley energy, or even the presence of spells around them. The more they accumulate, the stronger their spark grows—and the more draconic they become. But if the fire dims… so too does their connection to what they are becoming. This need creates tension, obsession, and sometimes danger. Where true dragons are born into splendor, demi-dragons must steal fragments of it, piece by piece.

Elf Demi-Dragon Traits

Your lineage form grants you unnatural abilities—remnants of draconic power forced into a mortal frame, honed by pain, instinct, and raw magic.

Ability Score Increase

Your Dexterity and Charisma score increase by 1.

Age

A demi-dragon can live for roughly four hundred years, starting from when they were first transformed.

Size

Demi-dragons have a body mass that is identical to that of their previous form. At most, a demi-dragon stands 4 feet tall from shoulder to the ground, and measures no longer than 16 feet from snout to tail tip, of which their body accounts for a maximum of 5 feet. Your size is Medium or Small, chosen when you select this race.

Speed

Your base walking speed is 30 feet.

Darkvision

You have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

Fey Ancestry

You have advantage on saving throws against being charmed, and magic can’t put you to sleep.

Trance

Elves don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

Transmutation

You can shift between your original elven form and the draconic shape forged through your metamorphosis.

Starting at 1st level, as a bonus action, you can transform into your dragon form, or revert back to your elvish form. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a short or long rest.

Transforming in either direction—elvish to dragon or dragon to elvish—counts as one use.

While in your dragon form, you have access to your Dragon Scales, Mythic Build, and Natural Weapons features.

These features are suppressed while in your elvish form.

Dragon Scales

Your magical essence enhances your protective scales. While you aren't wearing armor, your Armor Class equals 10 + your Constitution modifier + your Charisma modifier.

Mythic Build

You count as one size category larger when determining your carrying capacity and the weight you can push, drag, or lift.
Your claws have enough manual agility to manipulate objects as normal, but you have disadvantage on attack rolls made with weapons that have the ammunition or two-handed properties, and receive no benefit from wielding shields. In order to wear armor, you must have it specially constructed, costing twice the normal rate.

Natural Weapons

You have access to an arsenal of natural weapons. These natural weapons count as martial melee weapons for you, and you are proficient with them. You can use them to make melee weapon attacks, and you add your Strength modifier to the attack and damage rolls when you attack with them. Your fanged maw deals 1d12 piercing damage on a hit. Your lashing tail has the reach property and deals 1d10 bludgeoning damage. Your rending claws deal 1d6 slashing damage. When you take the Attack action and attack with your claw, you can use your bonus action to make an additional claw attack.

Inheritance

Your connection to a particular type of true dragon manifests as a related skill. You gain proficiency with one of the following skills of your choice: Arcana, Acrobatics, Deception, History, and Persuasion.

Languages

You can speak, read, and write Common, Elvish and Draconic.
