Use your Athletics expertise (+10) and Rage advantage to grapple the target. Once held, deal 1d4 damage automatically at the start of your turn. You can then use your bonus action to knee them (unarmed strike for 1d8+STR) and your movement to drag them into dangerous terrain.

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.

Your unarmed strikes can deal bludgeoning damage equal to 1d6 + STR mod 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.

In battle, you fight with primordial ferocity. You have advantage on Strength checks and Strength saving throws, a +2 bonus to damage rolls with Strength weapons, and resistance to bludgeoning, piercing, and slashing damage. You cannot cast spells.

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.

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.

You have advantage on Dexterity saving throws against effects that you can see, such as traps and spells. To gain this benefit, you must not be blinded, deafened, or incapacitated.

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.

You gain proficiency in one skill, expertise in another, and +1 to Strength. (Applied: Intimidation and Athletics expertise).

You can always find a place to perform in any place that features combat for entertainment. You receive free lodging and food of a modest or comfortable standard as long as you perform each day.
