Jsk Path of the Raider

Versatile Warrior
At 3rd level, you can adapt to most fighting situations and give yourself an advantage. You gain the following benefits:
 * Any versatile weapon that you are wielding in one hand deals damage as if you were wielding it with two hands. Any versatile weapon that you are wielding with two hands scores a critical hit on a roll of 19 or 20.
 * When a creature has its maximum amount of hit points, you make Attacks against that creature with advantage.
 * You deal double damage to objects and structures with Actions or Attacks that use Strength.

Mortal Strike
At 6th level, your Attacks are precise and deadly, allowing you to deliver a mortal blow. You gain the following benefits. When a creature takes a mortal blow, it must succeed on a Constitution saving throw against a DC equal to 8 + your proficiency bonus + your Strength modifier. On a failed save, the creature starts to bleed for 1 minute.
 * When you score a critical hit with a melee Attack that that uses Strength, you deliver a mortal blow.
 * Whenever you have advantage on a melee Attack that uses Strength, you can deliver a mortal blow to the target if the lower of the two d20 rolls would also hit the target.

Savage Gambit
At 10th level, you can sacrifice accuracy for lethality. When you make your first Attack on your turn, you can decide to Attack visciously. Doing so gives you disadvantage on melee weapon Attacks using Strength during this turn, but your successful melee weapon Attacks that use Strength will deal additional damage equal to your Barbarian level.

Concussive Strike
At 14th level, when you take the Attack action on your turn you can attempt to stun a creature in place of one of your Attacks. The creature must succeed on a Constitution saving throw against a DC equal to 8 + your proficiency bonus + your Strength modifier, or become stunned until the end of its next turn. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. A creature that is two or more sizes larger than you makes this saving throw with advantage.
