Avatar of the Chromatic Dragon

Description:
You channel the might of Tiamat herself, transforming into an avatar of chromatic dragon power. For the duration of the spell, your body becomes wreathed in elemental energy based on the five chromatic dragon types: fire, cold, lightning, poison, and acid. Your physical form reflects the raw power of Tiamat, and you gain the following benefits:

• Draconic Resistance: You gain resistance to one of the following damage types of your choice: fire, cold, lightning, poison, or acid.
• Elemental Fury: As part of your action on each of your turns, you can unleash a breath attack in a 15-foot cone. The damage type matches your chosen resistance and deals 6d6 damage. Creatures in the cone must make a Dexterity saving throw, taking full damage on a failed save, or half on a successful one.
• Flight: You sprout ethereal dragon wings, granting you a flying speed of 60 feet.
• Draconic Terror: As a bonus action, you can cause creatures of your choice within 30 feet to make a Wisdom saving throw. On a failed save, they are frightened of you until the end of their next turn.

Draconic Empowerment:
If the damage type of your breath attack matches your Draconic Ancestry, you can choose to deal an additional 2d6 of the same damage type whenever you use the breath attack.

At Higher Levels:
When you cast this spell using a spell slot of 7th level or higher, the damage of your breath attack increases by 1d6 for each slot level above 6th.
