Natural Athlete. You have proficiency in the Athletics skill.

Shifting Feature. Whenever you shift, you gain 1d6 additional temporary hit points. While shifted, you have a +1 bonus to your Armor Class.

Great Weapon Fighting
When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Darkvision. You have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

Speak with animals: You have an innate ability to communicate with beasts that your lineage hails from Through sounds and gestures, you can communicate simple ideas to a beast as an action, and can read its basic mood and intent. You learn its emotional state, its short-term needs (such as food or safety), and actions you can take (if any) to persuade it to not attack. You cannot use this ability against a creature that you have attacked within the past 10 Minutes.

Shifting. As a bonus action, you can assume a more bestial appearance. This transformation lasts for 1 minute, until you die, or until you revert to your normal appearance as a bonus action. When you shift, you gain temporary hit points equal to your level + your Constitution modifier (minimum of 1 temporary hit point). You also gain additional benefits that depend on your shifter subrace, described below.
Once you shift, you can't do so again until you finish a short or long rest.

Tough
Your hit point maximum increases by an amount equal to twice your level when you gain this feat. Whenever you gain a level thereafter, your hit point maximum increases by an additional 2 hit points.

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 +2 bonus to the damage roll. This bonus increases as you level.
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 maximum number of times for your barbarian level, you must finish a long rest before you can rage again. You may rage 2 times at 1st level, 3 at 3rd, 4 at 6th, 5 at 12th, and 6 at 17th.

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
At 2nd 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.

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 Knowledge
3rd-level barbarian optional feature

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.

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.

Draconic Ancestry
3rd-level Path of the Wyrmblood feature
Whether by ritual, ancestry, or happenstance, your bloodline bears draconic power. Choose one of the Dragons below that best represents the dragon whose power resides within you. You gain resistance to your Dragon's associated Element. (Fire)

You also learn to speak, read, and write Draconic.

Draconic Fury
3rd-level Path of the Wyrmblood feature
While Raging, you manifest chromatic scales that grant you
a bonus to your Armor Class equal to your Rage damage bonus. Also, once per turn when you hit a creature with a weapon attack, you can deal a bonus 1d6 Element damage.

Gift of the Chromatic Dragon
FTD
p17
You've manifested some of the power of chromatic dragons, granting you the following benefits:
Chromatic Infusion. As a bonus action, you can touch a simple or martial weapon and infuse it with one of the following damage types: acid, cold, fire, lightning, or poison. For the next minute, the weapon deals an extra 1d4 damage of the chosen type when it hits. After you use this bonus action, you can't do so again until you finish a long rest.

Reactive Resistance. When you take acid, cold, fire, lightning, or poison damage, you can use your reaction to give yourself resistance to that instance of damage. You can use this reaction a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Great Weapon Master
PHB
p167
You've learned to put the weight of a weapon to your advantage, letting its momentum empower your strikes. You gain the following benefits:
On your turn, when you score a critical hit with a melee weapon or reduce a creature to 0 hit points with one, you can make one melee weapon attack as a bonus action.
Before you make a melee attack with a heavy weapon that you are proficient with, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
