Base Class: Sorcerer
Draconic bloodline is a interesting idea however it doesn't have any of the other dragon lines
Gem Dragon Ancestor
At 1st level, you choose one type of dragon as your ancestor. The damage type associated with each dragon is used by features you gain later.
Draconic Ancestry
| Dragon | Damage Type |
|---|---|
|
Amethyst |
Force |
|
Crystal |
Radiant |
|
Emerald |
Psychic |
|
Sapphire |
Thunder |
|
Topaz |
Necrotic |
You can speak, read, and write Draconic. Additionally, whenever you make a Charisma check when interacting with dragons, your proficiency bonus is doubled if it applies to the check.
Draconic Resilience
As magic flows through your body, it causes physical traits of your dragon ancestors to emerge. At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.
Additionally, parts of your skin are covered by a thin sheen of dragon-like scales. When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier.
Elemental Affinity
Starting at 6th level, when you cast a spell that deals damage of the type associated with your draconic ancestry, you can add your Charisma modifier to one damage roll of that spell. At the same time, you can spend 1 sorcery point to gain resistance to that damage type for 1 hour.
Dragon Wings
At 14th level, you gain the ability to sprout a pair of dragon wings from your back, gaining a flying speed equal to your current speed. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn.
You can’t manifest your wings while wearing armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.
Gem Draconic Breath
Beginning at 18th level, you can channel the draconic power of your gem ancestor, causing you to unleash a powerful breath weapon. As an action, you can spend 6 sorcery points to draw on this power exhale a devastating cone of the chosen gem dragon type. in a 50-foot cone. Each creature in that area must make a Charisma saving throw (DC = 16 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 8d10 damage of the type associated with your Gem Ancestry. On a successful save, it takes half as much damage.
