Path of the Lightning Slinger

The rage of a barbarian can take many forms, from a violent frenzy, to gaining the protection of their ancestors. Those who follow the Path of the Lightning Slinger embody the essence of a storm, their roar becoming a thunderclap and their strikes turning into bolts of lightning.

Roar of the Thunderbolt

At 3rd level, you gain the power to channel all your might into a single, terrifying roar. When you rage, and as a bonus action while raging, you can utter a powerful roar. Each creatures in a 60-foot radius must make a Constitution saving throw against your AC, taking 2d6 thunder damage and becoming frightened for 1 minute on a failed save. On a successful save, the creature takes half as much damage and isn’t frightened. At 6th level, the damage increases to 3d6, and at 10th level, the damage increases to 4d6.

Spark of Power

Also at 3rd level. You become able to channel a spark of electricity when you attack. While raging, all your weapon attacks deal an extra 1d10 lightning damage. At 10th level, this damage increases to 2d10.

Lightning Rod

At 6th level, your inner power attracts enemies like a lightning rod. When you rage, and as a bonus action while raging, you can force a number of creatures up to your proficiency bonus to make a Charisma saving throw against your AC. On a failed save, the creature is forced to attack only you, and does so with disadvantage for 1 minute. In addition, you have resistance to all damage dealt by them. On a successful save, the effect lasts for only 5 rounds. You can use this ability a number of times equal to half your proficiency bonus, and you regain all expended uses on a long rest.

Arcing Strike

At 10th level, your attacks become a furious barrage of lightning that hit anyone in your path. When you make an attack, every creature in a 10-foot radius of you takes half the damage dealt as lightning damage.

Speed and Shield of Lightning

At 14th level, your very body can be supercharged by lightning or be protected by it. On your turn, you can choose one of the following abilities:

 

Speed of Lightning: When you take the Attack action on your turn, you can choose to make a number of attacks equal to your proficiency bonus, however you do not gain the benefits of Spark of Power or Arcing Strike when making these attacks. These attacks are made with advantage, and you are able to reroll one of the dice once.

Shield of Lightning:  As a bonus action, you can create a field of lightning bolts surrounding you at all times. Any other creature who starts their turn within a 10-foot radius of you takes a number of d10s equal to your Strength modifier as damage. This effect lasts until the start of your next turn.
