Path of the Dragon

The first warriors of this path were the dragonborn, who harnessed their draconic heritage into mighty strength. As time has passed, other warriors learned this path as well. Barbarians following the Path of the Dragon draw their power from their draconic blood, a draconic ancestor, a blessing from a dragon, or a spiritual connection to a dragon.

These Barbarians channel the power of dragons to destroy their foes. Their personality is often influenced by their draconic heritage or dragon that pushed them on this path. Among dragonborn, these barbarians are seen as champions of their clans while among non-dragonborn, this power can inspire fear, awe, or both.

This is not my own work, but an attempt to port a homebrew barbarian path I liked from reddit onto D&D beyond for use. All credit goes to u/fanatic66 for putting this together a year ago.

Gift of the Dragon

At 3rd level, your draconic affinity hardens your skin and you gain a +2 bonus to your armor class. You cannot gain this bonus if you are wearing heavy armor.

Additionally, you gain the power of one specific type of dragon from the table below. This choice determines the damage type of Draconic Fury.

You can also speak, read, and write Draconic.

Draconic Fury

Starting when you choose this path at 3rd level, you can channel the fury of a dragon into your weapon strikes. While you’re raging, the first creature you hit on each of your turns with a weapon attack takes extra damage equal to 1d6 + half your barbarian level. The extra damage is dependent on your choice from Gift of the Dragon. 

Acid

The extra damage you deal with Draconic Fury is acid.

Cold

The extra damage you deal with Draconic Fury is cold.

Fire

The extra damage you deal with Draconic Fury is fire.

Lightning

The extra damage you deal with Draconic Fury is lightning.

Poison

The extra damage you deal with Draconic Fury is poison.

Draconic Presence

At level 6, others can sense your growing draconic connection. You gain proficiency in the Intimidation skill if you don't already have it. Your proficiency bonus is doubled for any ability check you make that uses Intimidation.

In addition, you gain resistance to the damage type from your Gift of the Dragon.

Acid

You are resistant to Acid damage.

Cold

You are resistant to Cold damage.

Fire

You are resistant to Fire damage.

Lightning

You are resistant to Lightning damage.

Poison

You are resistant to Poison damage.

Dragonic Terror

Beginning at 10th level, you can use your action to frighten enemies around you. Choose any creatures that you can see within 30 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or be frightened of you until the end of your next turn.

If the creature succeeds on its saving throw or is no longer frightened, you can't use this feature on that creature again for 24 hours.

Dragon Flight

At 14th level, when you enter a rage, you gain the ability to sprout a pair of dragon wings from your back, gaining a flying speed equal to your current speed. They last until your rage ends or you dismiss them on your turn.

You can’t manifest your wings while wearing armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.
