You have made a contract with a legendary, ancient dragon. Or perhaps you are descended from one. Either way, over time, you will embrace the dragon within. It starts with subtle physical changes and an affinity for one energy type before and ends with you embracing the transformative and magical powers of a legendary dragon. 

Draconic Spells

The Wyrm lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you. The spells listed here are all available via the basic rules. If you or your DM would like to choose different ones according to what you have access to, feel free to make a copy of this subclass and edit accordingly.

Spell Level	Spells
1st	command, burning hands
2nd	alter self, enlarge/reduce
3rd	fireball, fear
4th	secret chest, wall of fire
5th	dominate person, commune

Dragon's Conviction

Furthermore, whenever you bring an enemy to 0 HP using a spell of the energy type associated with your patron energy type, you gain temporary HP equal to your CHA modifier + your warlock level. In addition, your eldritch blast cantrip now does damage of the energy type associated with your patron, or force damage as you choose.

You will have to note this change in your spell notes and customization options of your character sheet. 

Dragon Soul

When you do damage with the elemental type that is associated with your dragon patron, you also gain the force, psychic, necrotic or radiant type added to that damage type. 

For example, if your patron is an evil red dragon, any time you deal fire damage it also counts as psychic. If your patron is a good aligned bronze dragon, your lightning damage is also considered radiant. DM discretion is required. 

Because of this extra damage type, a creature must have resistance or immunity to both types in order to receive resistance or immunity to your attack. For example, if the target has fire resistance and you cast burning hands as a Warlock of a good aligned gold dragon. Your burning hands is considered fire and radiant damage. The target's fire resistance does not apply against your burning hands because they have no resistance to radiant damage. If the target has immunity to fire but resistance to radiant, then the resistance applies, but not the immunity. 

Finally, every spell attack, weapon attack, or unarmed attack you make (including from magic items) deals an extra amount of this combined energy type equal to your Charisma modifier -- even if the damage is of the opposite energy type. For example, if you deal a combined acid and necrotic damage, but you cast Ray of Frost, you deal cold damage plus acid and necrotic equal to your Charisma modifier. 

Dragon Aura

You gain an aura which grants some aspects of a dragon transformation, including wings and natural armor.

You gain

• a natural armor bonus to AC equal to your CHA modifier when you are not wearing armor.
• A fly speed equal to your walking speed. 

Also, if you deal damage to a target, you can make an Intimidate check vs their Charisma save as a bonus action against that target. If they fail, they are frightened of you until they or their allies deal damage to you or 1 minute, whichever passes sooner. Pass or fail, a target can only be subjected to this check once every 24 hours. 

Dragon Body

Once per long rest, you may transform into a young adult dragon of the same type as your dragon patron. This ability functions exactly as True Polymorph. You may use your warlock spells and abilities while so transformed. 

If you use this ability every day for a year, the duration extends to 8 hours.

If you use this ability every day for ten years, your natural form becomes that of the dragon and your original form is what you transform into. You age as a dragon ages, growing in size and power over time, thus granting you effective immortality. You are now, for all purposes, a dragon with warlock levels.
