Barbarian (human)

 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.

Action Melee Attack. Melee Weapon Attack: + 5 to hit, reach 5 ft., 1 target. Hit: 9 (d12 + 3) [Slashing] damage. 

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 that increases as you gain levels as a barbarian, as shown in the Rage Damage column of the Barbarian table. (+ 2)
• 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.
