A fierce warrior of primitive background who can enter a battle rage

People of towns and cities take pride in how their civilized ways set them apart from animals, as if denying one’s own nature was a mark of superiority. To a barbarian, though, civilization is no virtue, but a sign of weakness. The strong embrace their animal nature keen instincts, primal physicality, and ferocious rage. Barbarians are uncomfortable when hedged in by walls and crowds. They thrive in the wilds o f their homelands: the tundra, jungle, or grasslands where their tribes live and hunt.
Barbarians come alive in the chaos of combat. They can enter a berserk state where rage takes over, giving them superhuman strength and resilience. A barbarian can draw on this reservoir of fury only a few times without resting, but those few rages are usually sufficient to defeat whatever threats arise.

Not every m ember of the tribes deemed “barbarians” by scions of civilized society has the barbarian class. A true barbarian among these people is as uncommon as a skilled fighter in a town, and he or she plays a similar role as a protector of the people and a leader in times of war. Life in the wild places of the world is fraught with peril: rival tribes, deadly weather, and terrifying monsters. Barbarians charge headlong into that danger so that their people don’t have to. Their courage in the face of danger makes barbarians perfectly suited for adventuring. Wandering is often a way of life for their native tribes, and the rootless life of the adventurer is little hardship for a barbarian. Some barbarians miss the close-knit family structures of the tribe, but eventually find them replaced by the bonds formed among the members of their adventuring parties.

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.

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.

Starting at 2^nd 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.

At 2^nd level, you gain an uncanny sense of when things nearby aren’t as they should be, giving you an edge when you dodge away from danger. You have advantage on Dexterity saving throws against effects that you can see, such as traps and spells. To gain this benefit, you can’t be blinded, deafened, or incapacitated.

At 3^rd level, you choose a path that shapes the nature of your rage. Choose the Path of the Berserker or the Path of the Totem Warrior, both detailed at the end of the class description. Your choice grants you features at 3^rd level and again at 6^th, 10^th, and 14^th levels.

When you reach 4^th level, and again at 8^th, 12^th, 16^th, and 19^th 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.

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

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

By 7^th 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.

Beginning at 9^th 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 13^th level and three additional dice at 17^th level.

Starting at 11^th 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.

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

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

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

For some barbarians, rage is a means to an end—that end being violence. The Path o f the Berserker is a path of untrammeled fury, slick with blood. As you enter the berserker’s rage, you thrill in the chaos of battle, heedless of your own health or well-being.

Starting when you choose this path at 3^rd level, you can go into a frenzy when you rage. If you do so, for the duration of your rage you can make a single melee weapon attack as a bonus action on each o f your turns after this one. When your rage ends, you suffer one level of exhaustion.

Beginning at 6^th level, you can’t be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.

Beginning at 10^th level, you can use your action to frighten someone with your menacing presence. When you do so, choose one creature that you can see within 30 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or be frightened of you until the end of your next turn. On subsequent turns, you can use your action to extend the duration of this effect on the frightened creature until the end of your next turn. This effect ends if the creature ends its turn out of line of sight or more than 60 feet away from you. If the creature succeeds on its saving throw, you can't use this feature on that creature again for 24 hours.

Starting at 14^th level, 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.

The Path of the Totem Warrior is a spiritual journey, as the barbarian accepts a spirit animal as guide, protector, and inspiration. In battle, your totem spirit fills you with supernatural might, adding magical fuel to your barbarian rage. Most barbarian tribes consider a totem animal to be kin to a particular clan. In such cases, it is unusual for an individual to have more than one totem animal spirit, though exceptions exist.

Yours is a path that seeks attunement with the natural world, giving you a kinship with beasts. At 3^rd level when you adopt this path, you gain the ability to cast the beast sense and speak with animals spells, but only as rituals.

At 3^rd level, when you adopt this path, you choose a totem spirit and gain its feature. You must make or acquire a physical totem object—an amulet or similar adornment—that incorporates fur or feathers, claws, teeth, or bones of the totem animal. At your option, you also gain minor physical attributes that are reminiscent of your totem spirit. For example, if you have a bear totem spirit, you might be unusually hairy and thickskinned, or if your totem is the eagle, your eyes turn bright yellow.Your totem animal might be an animal related to those listed here but more appropriate to your homeland. For example, you could choose a hawk or vulture in place of an eagle.
Bear. While raging, you have resistance to all damage except psychic damage. The spirit of the bear makes you tough enough to stand up to any punishment.
Eagle. While you're raging and aren’t wearing heavy armor, other creatures have disadvantage on opportunity attack rolls against you, and you can use the Dash action as a bonus action on your turn. The spirit of the eagle makes you into a predator who can weave through the fray with ease.
Wolf. While you're raging, your friends have advantage on melee attack rolls against any creature within 5 feet of you that is hostile to you. The spirit of the wolf makes you a leader of hunters.

At 6^th level, you gain a magical benefit based on the totem animal of your choice. You can choose the same animal you selected at 3^rd level or a different one.
Bear. You gain the might of a bear. Your carrying capacity (including maximum load and maximum lift) is doubled, and you have advantage on Strength checks made to push, pull, lift, or break objects.
Eagle. You gain the eyesight of an eagle. You can see up to 1 mile away with no difficulty, able to discern even fine details as though looking at something no more than 100 feet away from you. Additionally, dim light doesn't impose disadvantage on your Wisdom (Perception) checks.
Wolf. You gain the hunting sensibilities of a wolf. You can track other creatures while traveling at a fast pace, and you can move stealthily while traveling at a normal pace.

At 10^th level, you can cast the commune with nature spell, but only as a ritual. When you do so, a spiritual version of one of the animals you chose for Totem Spirit or Aspect of the Beast appears to you to convey the information you seek.

At 14^th level, you gain a magical benefit based on a totem animal of your choice. You can choose the same animal you selected previously or a different one.
Bear. While you’re raging, any creature within 5 feet of you that’s hostile to you has disadvantage on attack rolls against targets other than you or another character with this feature. An enemy is immune to this effect if it can’t see or hear you or if it can’t be frightened.
Eagle. While raging, you have a flying speed equal to your current walking speed. This benefit works only in short bursts; you fall if you end your turn in the air and nothing else is holding you aloft.
Wolf. While you’re raging, you can use a bonus action on your turn to knock a Large or smaller creature prone when you hit it with melee weapon attack.
