Putting yourself in just the right position as you strike, your unbalancing hit sends a retreating opponent into a reeling stumble and then the ground.

Not just commiting to an assault, you shoulder into it with all the strength you can bear and deliver hits that resonate in the very bones of your foes.

You set yourself firmly in place, determined not to move.

After you slam your weapon into an opponent you work the momentum of the blow into another strike at a second enemy nearby in a devastating display of might.

When you hit with a melee weapon attack using a weapon with the heavy property, you can use your reaction to make an additional melee weapon attack against a second creature that is also within your reach.

You have a limited well of stamina that you can draw on to protect yourself from harm.

You regain hit points equal to 1d6 + your proficiency bonus + your Constitution modifier (minimum 0).

Digging within, you stave off the call of death and surge renewed towards your foes.

When you are reduced to 0 hit points, you can use your reaction to heal a number of hit points equal to your proficiency bonus. 

You permanently mark your foe with your sword.

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.
