Also, choose from a Dragon Type from Draconic Blessing table. The damage type, breath weapon and color associated with each dragon is used by features you gain later.

From 1st level, your god bestows you with the blessing of the mighty dragons. You can read, write, and speak Draconic.

Gods of dragons - including Bahamut, Tiamat, Faluzure, Io, and various lesser deities - are few compared to other gods but inspire fear and awe from many. Their followers are mighty dragons or more mortal servants such as dragonborn, kobolds, lizardfolk, or others that revere the legendary dragon gods. In particular, Bahamut and Tiamat both have a strong following of non-draconic worshippers. Devotees of the Platinum Dragon, king of metallic dragons, spread their god's ideals of justice, compassion, and goodness. Meanwhile, worshippers of the evil Dragon Queen, mother of chromatic dragons, revel in her greed and need to elevate dragons above all others. Clerics of the dragon gods glorify the power of dragons, while seeking to assist and protect the dragons their god favors.

Channel Divinity: Dragon Wrath

Starting at 2nd level, as an action, you can use your Channel Divinity to unleash a devastating exhalation of energy. Your Draconic Blessing determines the size, shape, and damage type of your breath weapon.

When you use your breath weapon, each creature in the area of the exhalation must make a saving throw, the type of which is determined by your Draconic Blessing. A creature takes 3d8 + your cleric level damage on a failed save, and half as much damage on a successful one.

Legendary Protection

Starting at 6th level, your deity rewards you with the fabled protection of their draconic children. You gain resistance to the damage type of your Draconic Blessing.

You can also extend your protection to others. When you cast absorb elements, you can choose a creature within 30 feet of you. They are also affected by your absorb elements spell.

Divine Strike

At 8th level, you gain the ability to infuse your weapon strikes with the elemental destruction of dragons. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 damage of the same type of your Draconic Blessing. When you reach 14th level, the extra damage increases to 2d8.

Shock and Awe

At 17th level, you can unleash a true dragon's roar that terrifies your enemies but inspires your allies. As an action, all enemies within 30 feet of you must make a Wisdom saving throw against your Spell DC. A target automatically succeeds on the save if it can't hear or see you.

On a failed save, a target becomes frightened of you for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to your Dragon Wrath for the next 24 hours.

All friendly creatures within 30 feet of you can make their next attack with advantage or make a saving throw against one effect on themselves.
