Path of the Dragonwatchers

The Path of the Dragonwatchers is walked by warriors chosen to defend the world. They have been chosen by powerful dragons to protect the world in their name. These barbarians are only chosen because their bodies are capable of holding the powers given to them by the dragons. It is from this power that they become extremely resilient while they rage. Extremely powerful Dragonwatchers have even been able to expel draconic energy and some of the most powerful Dragonwatchers have large powerful wings sprout from their backs. 

Draconic Endurance

At 3rd level, your hit point maximum increases by 3 and increases by 1 again whenever you gain a level in this class.

In addition, when you rage, you get resistance to acid, cold, fire, lightning, and poison damage.

Dragons Awareness

At 3rd level, you get blindsight for 15 ft. This increases to 30 ft at 10th level.

Draconic Infusion

Starting at level 6, while raging, your weapon attacks deal an extra 1d6 damage. The damage type can be acid, cold, fire, lightning, or poison. You choose the damage type when you enter your rage. 

The extra damage increases to 2d6 at 10th level. 

Enhanced Dragons Awareness

You get blindsight for 30 ft.

Draconic Eruption

At level 10, while raging, you can use your action to expel a 30 ft cone or 60 ft long 10 ft wide line of elemental energy. Each creature in the area must make a DEX saving throw taking half your barbarian level in d8's on a failed save, taking half as much on a success. The damage is the same damage type as your Draconic Infusion Feature. The saving throw DC is 8 + your Proficiency Bonus + your Strength modifier.
You can use this feature once per long rest for free. You will gain 1 level of exhaustion for every use of this feature after the first. You will get the exhaustion after your rage ends.

Dragon's Fury

Starting at level 14, when you enter your rage, large wings sprout from your back. You gain a 60 ft flying speed and when a creature gets within 10 ft of you, you can use your reaction to force them to make a STR saving throw or be pushed back 20 ft and land prone. If they are thrown into a wall (or anything similar) they take 3d10 bludgeoning damage. The saving throw DC is equal to your Draconic Eruption feature.
