Equipment

You start with the following equipment, in addition to the equipment granted by your background:

• (a) a greataxe or (b) any martial melee weapon
• (a) two handaxes or (b) any simple weapon
• An explorer's pack and four javelins

Rage

In battle, you fight with primal ferocity. On your turn, you can enter a rage as a bonus action.

While raging, you gain the following benefits if you aren't wearing heavy armor:

• You have advantage on Strength checks and Strength saving throws.
• When you make a melee weapon attack using Strength, you gain a bonus to the damage roll equal to your proficiency bonus.
• You have resistance to bludgeoning, piercing, and slashing damage.

If you are able to cast spells, you can't cast them or concentrate on them while raging.

Your rage lasts for 1 minute. It ends early if you are knocked unconscious or if your turn ends and you haven't attacked a hostile creature since your last turn or taken damage since then. You can also end your rage on your turn as a bonus action.

Once you have raged the number of times shown for your barbarian level in the Rages column of the Barbarian table, you must finish a long rest before you can rage again.

Unarmored Defense

While you are not wearing any armor, your armor class equals 10 + your Dexterity modifier + your Constitution modifier. You can use a shield and still gain this benefit.

Danger Sense

You gain an uncanny sense of when things aren't as they should be, giving you an edge when you dodge perils. You have advantage on Dexterity saving throws unless you are incapacitated.

Reckless Attack

Starting at 2nd level, you can throw aside all concern for defense to attack with fierce desperation. When you make your first attack on your turn, you can decide to attack recklessly. Doing so gives you advantage on melee weapon attack rolls using Strength during this turn, but attack rolls against you have advantage until your next turn.

Primal Path

At 3rd level, you choose a path that shapes the nature of your rage. Your choice grants you features at 3rd level and again at 6th, 10th, and 14th levels.

Primal Knowledge

When you reach 3rd level and again at 10th level, you gain proficiency in one skill of your choice from the list of skills available to barbarians at 1st level.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Extra Attack

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Fast Movement

Starting at 5th level, your speed increases by 10 feet while you aren't wearing heavy armor.

Feral Instinct

By 7th level, your instincts are so honed that you have advantage on initiative rolls.

Additionally, if you are surprised at the beginning of combat and aren't incapacitated, you can act normally on your first turn, but only if you enter your rage before doing anything else on that turn.

Instinctive Pounce

At 7th level, as part of the bonus action you take to enter your rage, you can move up to half your speed.

Brutal Strike

You gain the benefit below, and you gain an additional benefit when you reach 13th level and 17th level in this class.

If you use Reckless Attack, you can forgo any Advantage on one Strength-based attack roll of your choice on your turn. The chosen attack roll mustn't have Disadvantage. If the chosen attack roll hits, the target takes an extra 1d10 damage of the same type dealt by the weapon or Unarmed Strike, and you can cause one Brutal Strike effect of your choice.

You have the following effect options.

Forceful Blow. The target is pushed 15 feet straight away from you. You can then move up to half your Speed straight toward the target without provoking Opportunity Attacks.

Hamstring Blow. The target’s Speed is reduced by 15 feet until the start of your next turn. A target can be affected by only one Hamstring Blow at a time— the most recent one.

Improved Brutal Strike (13th Level)

At 13th level, you have honed new ways to attack furiously. The following effects are now among your Brutal Strike options.

Staggering Blow. The target has Disadvantage on the next saving throw it makes, and it can’t make Opportunity Attacks until the start of your next turn.

Sundering Blow. Before the start of your next turn, the next attack roll made by another creature against the target gains a +5 bonus to the roll. An attack roll can gain only one Sundering Blow bonus.

Improved Brutal Strike (17th Level)

Starting at 17th level, the extra damage of your Brutal Strike increases to 2d10. In addition, you can use two different Brutal Strike effects whenever you use your Brutal Strike feature.

Brutal Critical (Optional)

This 9th-level feature replaces the Brutal Strike feature. You gain no benefit from the replaced feature and don't qualify for anything in the game that requires it.

Beginning at 9th level, you can roll one additional weapon damage die when determining the extra damage for a critical hit with a melee attack.

This increases to two additional dice at 13th level and three additional dice at 17th level.

Relentless Rage

Starting at 11th level, your rage can keep you fighting despite grievous wounds. If you drop to 0 hit points while you're raging and don't die outright, you can make a DC 10 Constitution saving throw. If you succeed, you drop to 1 hit point instead.

Each time you use this feature after the first, the DC increases by 5. When you finish a short or long rest, the DC resets to 10.

Persistent Rage

Beginning at 15th level, your rage is so fierce that it ends early only if you fall unconscious or if you choose to end it.

Indomitable Might

Beginning at 18th level, if your total for a Strength check is less than your Strength score, you can use that score in place of the total.

Primal Champion

At 20th level, you embody the power of the wilds. Your Strength and Constitution scores increase by 4. Your maximum for those scores is now 24.
