You strike a spellcaster and disrupt their control over magic, fracturing the power behind a spell and transforming the energy so it roots them to the spot.

You charge a spellcaster in order to interrupt their spell.

When a creature you can see casts a spell, you can use your reaction to move up to your Speed. If you end your movement adjacent to that creature, you can make a melee weapon attack against it. On a critical hit, the spell is interrupted (expending the spell slot) and has no effect.

The battle around you narrows as you focus your ire on a single opponent, ignoring other threats or enemies.

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.
 

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

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.

You use a melee weapon to strike a foe from a distance.

Choose a weapon when you learn this combat maneuver. You can use the chosen weapon to strike a distant target with air pressure, giving your attack a normal range of 20 feet and long range of 60 feet. This functions as if your weapon had the thrown property except you don’t actually throw it. 

Mastery is making sure even a mistake becomes an opportunity. You follow through on a miss to attack a different enemy.

When you miss with a melee weapon attack against a creature, you can use your reaction to take your momentum and target a different creature within your reach with a melee attack using the same weapon. 

What you wield isn’t what makes you a deadly combatant—you are the weapon. Attaining mastery of some weaponry has taught you how to focus and bring all that practice to bear even with lethal implements you’ve never seen before.

You gain proficiency with all weapons (including rare weapons).
