You use all your senses to focus your attacks on a single enemy.

You gain blindsight out to a range of 30 feet. 

If a creature leaves the range of your blindsight, you can use your reaction to mark it as prey and move up to your Speed. The next melee weapon attack you make against that creature before the end of your next turn deals an additional weapon damage die.

A victorious battle cry strikes fear in the heart of your foes.

You leap and bound toward your enemy with animal fury.

You throw your body across the battlefield, careening around opponents in a route and manner that makes it difficult to anticipate where you’ll move next.

You unleash blow after blow, striking your opponent again and again, oblivious to your surroundings.

Make a melee weapon attack against a creature. On a hit, make another melee weapon attack. You can keep attacking until you miss. You cannot make more attacks than your proficiency bonus in this manner. 

Attack rolls against you have advantage until the beginning of your next turn.

You instinctively know when you hit an opponent’s weak spot and can muster an extra bit of force to devastating effect, causing your foe to suffer momentary fatigue.

Like a stalking predator you run down your prey and pounce with a lethal attack that throws your opponent to the ground or knocks them back.

By tapping into your basic survival instincts you not only unleash your potential—you make certain that every strike counts.

The minimum result on a damage die rolled with a natural weapon, unarmed strike, or weapon with the dual-wielding property is a 3.
 

The instant you sense an opponent has moved within your guard you immediately attack in response.

With two deft attacks you rend at your opponent, striking at them first to diminish their defenses then delivering a ferocious second blow.

When you activate this technique, you take the Attack action and make a weapon attack, as well as any additional attacks granted by Extra Attack. Until the start of your next turn, when you hit a creature with two or more melee weapon attacks, each hit after the first deals 1d8 extra damage.

You lash out with one strike that sets up another, faster and wilder attack.

You leap atop your enemy just as it attacks.

Every time you step, slide, or turn you do so more quickly than usual and it becomes much easier to hurl yourself about.

You increase the distance of your horizontal jumps by a number of feet equal to your proficiency bonus, and the distance of your vertical jumps by a number of feet equal to half your proficiency bonus. In addition, you gain an expertise die on Acrobatics checks and checks made to jump.

You move through the environment like a cat, running along walls and easily leaping across gaps.

Move 30 feet. Until the start of your next turn, you gain a climb speed equal to your Speed and your minimum jump distance increases to 10 feet vertically and 15 feet horizontally. 

Playing dead, you surprise your foe with a sudden attack.
