Rally

On your turn, you can use a bonus action and expend one superiority die to bolster the resolve of one of your companions.
When you do so, choose a friendly creature who can see or hear you.
That creature gains temporary hit points equal to the superiority die roll + your Charisma modifier.

Maneuvering Attack

When you hit a creature with a weapon attack, you can expend one superiority die to maneuver one of your comrades into a more advantageous position.
You add the superiority die to the attack's damage roll, and you choose a friendly creature who can see or hear you.
That creature can use its reaction to move up to half its speed without provoking opportunity attacks from the target of your attack.

Commander's Strike

When you take the Attack action on your turn, you can forgo one of your attacks and use a bonus action to direct one of your companions to strike.

That creature can immediately use its reaction to make one weapon attack, adding the superiority die to the attack's damage roll.

Second Wind

Watcher's Eye

Your experience in enforcing the law, and dealing with lawbreakers, gives you a feel for local laws and criminals. You can easily find the local outpost of the watch or a similar organization, and just as easily pick out the dens of criminal activity in a community, although you're more likely to be welcome in the former locations rather than the latter.
