Path of the Gladiator

For some barbarians, rage comes from years spent in the pits of the arena. The Path of the Gladiator is a path of intense fury, slick with blood, often at death's door. As you enter the Gladiator’s rage, you thrill in the throes of battle. The Gladiator focuses on the use of raw physical power honed to bring deadly destruction. Those who follow this path combine rigorous training with physical prowess to deal devastating blows in battle.

Savagery

Starting when you choose this path at 3rd level, you go into a frenzy when you rage. For the duration of your rage, you can make a melee weapon attack as a bonus action on each of your turns. Also, while raging, when you take damage from a creature that is within 5 feet of you, you can use your reaction to make a melee weapon attack against that creature.

In addition, improvised weapons and unarmed strikes deal 1d6 + your strength modifier.

Intimidating Cleave

You're used to being outnumbered, with no allies by your side. At 6th level when you gain this ability, while raging and if you have two or more enemies within five feet of you, and also no allies within ten feet, you can attack in a whirlwind of fury. After a successful melee attack against a target, and once damage has been rolled but before resistances/vulnerabilities are calculated, you may extend the damage to additional targets within range (Up to your strength modifier), reducing the damage each spread, (1/2, 1/3, 1/4, and so on), as long as the initial attack roll would hit the new target.

In addition, you add your strength modifier to intimidation checks.

Battle Master

Beginning at 10th level, you can wield a two-handed melee weapon as if it was one handed, including for use of weapons with the versatile property in regards to using the alternate damage dice.

In addition, your adaptability in battle allows you to use your own misfortune to your advantage; whenever you roll damage for a melee weapon, re-roll any dice that result in a 1, including the new rolls.

Gladiator's Resiliance

At 14th level, the bonus resistances from your rage are now permanent, and you gain resistance to fire, lightning, and cold damage while raging.

In addition, while raging you can use your raw strength to resist injury. Whenever you take damage to your non-temporary health, from a type which you have resistance to, add temporary hit points equal to your strength score, after the damage is applied. These temporary hit points are lost when you exit rage.

Whenever your current HP is less than half your maximum, your rage can extend to ten minutes instead of the usual one minute. Also, while raging below half health, you regain HP per minute equal to your strength modifier.
