You have created a pact with a draconic entity, whether otherworldly, ancient, or otherwise. The dragon's motives for making this pact is most likely beyond you, but may include using you to amass wealth and magic items for them, extend their influence, or sow destruction. In any case, even the least intelligent of dragons are hardly dumb, especially if they had the sense to make a warlock pact. Powerful entities which may create these pacts are any ancient dragon, Bahamut, Tiamat, or other dragon gods.

Draconic Boon

Your skin becomes thick and tough, like dragon hide. When you are not wearing armor, your armor class is equal to 13 + your Dexterity modifier, and you have resistance to your choice of fire, lightning, poison, acid, or cold damage.

You have chosen resistance to fire damage.

Draconic Boon Damage Resistance (Lightning)

Aura of Intimidation

Starting at 6th level, you can use a bonus action to force each creature you choose in a 20-foot radius to make a Wisdom saving throw or become frightened of you for 1 minute. A creature frightened in this way has their speed reduced to 0, and you have advantage on any Charisma (Intimidation) check against an affected creature. This condition ends on each creature affected that can see you if you take damage or fail a saving throw, ability check, or attack roll.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Improved Draconic Boon

Starting at 10th level, your connection to your draconic patron changes your physicality and abilities even more. You gain immunity to the damage type you chose. In addition, your base armor class increases to 15 + your Dexterity modifer when you aren't wearing armor. In addition, whenever you roll a 1 on a damage die for an effect that deals damage of the chosen type, you may reroll that die and must keep that roll.

Improved Draconic Boon (Acid)

You gain immunity to acid damage. In addition, you may reroll 1s for damage dice which deal acid damage.

Improved Draconic Boon (Cold)

You gain immunity to cold damage. In addition, you may reroll 1s on damage dice which deal cold damage.

Improved Draconic Boon (Fire)

Dragon's Transformation

Starting at 14th level, your patron allows you to take on an appearance much more similar to their own. You can cast true polymorph without expending a spell slot or a use of Mystic Arcanum. When you do this, you can only target yourself, and you can only change yourself into a dragon.

Once you use this feature, you can't use it again until you finish a long rest.
