Path of the Dragon Slayer

The rituals to create warriors whose strength rivals that of the great wyrms have long been lost to the public knowledge.  Such ideas are only found in the depths of both minds and woods, far from where any ordinary man could ever reach.  Yet, those that walk the Path of the Dragon Slayer are far from ordinary.  Using magics created by long-forgotten dragons seeking to rid themselves of potential rivals, barbarians of the Path of the Dragon Slayer are able to burn the unburnable, strike the unstrikable, and slay the unslayable.  

Dragonheart

The heart of a true dragon beats within your chest and its overwhelming prescence burns in your eyes.  When you choose this path at 3rd level, you choose one type of dragon as your progenitor. The damage type associated with each dragon is used by features you gain later.

Draconic Fury

You have learned to channel fury of the dragons during your rage to reinforce your body with their own scales.  Beginning at 3rd level, while you're raging, you gain resistance to your chosen Dragonheart damage type. Additionally, if you are not wearing armor while raging, you gain +2 to your AC as hardened scales cover your potential weak points.

Dragonstrike

Starting at 6th level, you gain the ability to channel the draconic power that fuels your rage into strikes that even pierce the souls of creatures who would normally ignore them. Once per turn, while you’re raging, any creature that you hit with a weapon attack takes extra damage equal to half of your barbarian level (rounded down). This extra damage’s type corresponds to your chosen Dragonheart damage type and ignores resistance to damage of the chosen type. If you attack a creature with immunity to your chosen damage type, the creature still takes half damage despite its immunity.

Furious Consumption

Your draconic resilience ascends beyond merely resisting damage.  Starting at 10th level, you gain the ability to physically consume the element tied to your chosen Dragonheart element and use its energy to heal your own wounds.  Whenever you are subjected to your chosen Dragonheart damage type while raging, you may use your reaction to instead take no damage and regain a number of hit points equal to half of the damage dealt.

Essence of the Dragon King

Starting at 14th level, the fury of the dragons has transformed your very being to something more than both human or dragon, a king among men and drakes. You no longer need to be raging to receive resistance to your chosen Dragonheart damage type. When you rage, or as a bonus action while raging, you may sprout a pair of dragon wings from your back, gaining a flying speed equal to your current speed. They last until you dismiss them as a bonus action 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.
