Slayer X | New Barbarian Subclass for Fifth Edition (Aberranterra)

Slayer X | New Barbarian Subclass for Fifth Edition by DMDave

At 3rd level, a barbarian gains the Primal Path feature. The following Wastelord option is available to a barbarian, in addition to those normally offered.

Path of Slayer X

Before the Fall, world governments were deadlocked in a race to create the ultimate killing machines. Set loose against opposing armies, these dangerous living-weapons could cut a swath through dozens—if not hundreds—of soldiers, tearing their enemies apart like paper dolls. While each program had a different name, generally, these soldiers-of-mass-destruction were known as Slayers X.

Now that the big governments of Before have collapsed, those who tread the Path of Slayer X wander the rad-wastes searching for purpose in a world gone mad. Most were left without memories of who they were. Many don’t even remember what was done to them; as time goes on, they learn more and more about their enhanced nature.

Internal Weaponry

At 3rd level, you discover that you’ve been enhanced with weapons within your body. Choose one of the following options:

Claws. You have steel claws that eject from your wrists, knuckles, or fingertips which act as natural weapons that replace your unarmed strike. As a bonus action, you can discharge or retract your claws. You gain the following benefits while you are unarmed and your claws are extended:

  • You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes.
  • On a hit, your unarmed strike deals 1d6 slashing damage instead of the normal damage of your unarmed strike.
  • When you use the Attack action with an unarmed strike on your turn, you can make one unarmed strike as a bonus action.
  • While raging, you can attack twice, instead of once, whenever you take the Attack action on your turn so long as you use your claws to make the attacks. At 5th level, when you gain the Extra Attack feature, you can attack three times using your claws.

Steel-Reinforced Arms. The muscles and bones in your arms have been augmented with magical steel. You gain the following benefits:

  • You have advantage on all Strength checks, even when you aren’t raging.
  • You can roll a d4 in place of the normal damage of your unarmed strike.
  • During a rage, if you make a Strength check or Strength saving throw and fail, you can reroll one of the d20s. You must take the new result even if it is lower.
  • The bonus to your damage rolls you gain while raging increases by 3.

Magical Enhancements

Starting at 6th level, your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. In addition, your unarmored defense improves. While you are not wearing any armor, you gain a magical +1 bonus to your AC.

Augmented Senses

At 10th level, your senses improve. While you are raging, you can see invisible creatures and objects as if they were visible, and you can see into the Ethereal Plane. Ethereal creatures and objects appear ghostly and translucent.

Lash Out

Once you reach 14th level, when you take damage from a creature that you can see, you can use your reaction to move up to half your movement speed towards the attacker and make one unarmed attack against it if you are able.
