Unarmed Fighting (TCE).

Your unarmed strikes can deal bludgeoning damage equal to 1d6 + your Strength modifier on a hit. If you aren't wielding any weapons or a shield when you make the attack roll, the d6 becomes a d8.
At the start of each of your turns, you can deal 1d4 bludgeoning damage to one creature grappled by you.

Second Wind

You have a limited well of stamina that you can draw on to protect yourself from harm. On your turn, you can use a bonus action to regain hit points equal to 1d10 + your fighter level.
Once you use this feature, you must finish a short or long rest before you can use it again.

Action Surge

On your turn, you can take one additional action.
Once you use this feature, you must finish a short or long rest before you can use it again.

Extra Attack

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

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.

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.
-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.

Ship's Passage

When you need to, you can secure free passage on a sailing ship for yourself and your adventuring companions. You might sail on the ship you served on, or another ship you have good relations with (perhaps one captained by a former crewmate). Because you're calling in a favor, you can't be certain of a schedule or route that will meet your every need. Your DM will determine how long it takes to get where you need to go. In return for your free passage, you and your companions are expected to assist the crew during the voyage.

Durable

Hardy and resilient, you gain the following benefits:

-Increase your Constitution score by 1, to a maximum of 20.
-When you roll a Hit Die to regain hit points, the minimum number of hit points you regain from the roll equals twice your Constitution modifier (minimum of 2).

Crusher

You are practiced in the art of crushing your enemies, granting you the following benefits:

-Increase your Strength or Constitution by 1, to a maximum of 20.
-Once per turn, when you hit a creature with an attack that deals bludgeoning damage, you can move it 5 feet to an unoccupied space, provided the target is no more than one size larger than you.
-When you score a critical hit that deals bludgeoning damage to a creature, attack rolls against that creature are made with advantage until the start of your next turn.
