Balthazar Ignacious, Lord of the Fight

Interception. When a creature Balthazar can see hits a target other than himself within 5 ft. of him with an attack, he can use his reaction to reduce the damage the target takes by 1d10+6 (to a minimum of 0 damage). He must be wielding a shield or a simple or martial weapon to use this reaction.

Second Wind. Once per short rest, Balthazar can use a bonus action to regain 1d10 + 20 HP.

Action Surge. He can take one additional action on your turn. This can be used 2 times per short rest.

Indomitable. Balthazar can reroll a saving throw that he fails. He must use the new roll. He can use this 3 times per long rest.

Legion Tactics. Balthazar gains a +1 bonus to AC for every two allies within 5 feet of him (up to a maximum of +3) while wielding a shield.

Maneuvers.

Disarming Attack (No action). When he hits with a weapon attack, he can expend one superiority die to add it to the damage and to disarm the target if it fails a STR saving throw (DC 19).

Distracting Strike (No action). When he hits with a weapon attack, he can expend one superiority die to add the total to the damage roll and the next attack roll against the target by an attacker other than him has advantage if the attack is made before the start of his next turn.

Goading Attack (No action). When he hits with a weapon attack, he can expend one superiority die to add the total to the damage roll and the target must make a WIS saving throw (DC 19). On failure, the target has disadvantage on all attack rolls against targets other than him until the end of his next turn.

Sweeping Attack (No action). When he hits with a melee weapon attack, he can expend one superiority die to deal damage to another creature within 5 ft. of the original target and within his reach (if the original attack would hit it) equal to the number he rolls on the superiority die.

Evasive Footwork (No Action). When he moves, he can expend one superiority die, rolling the die and adding the number rolled to his AC until he stops moving.

Commander’s Strike. When Balthazar takes the Attack action on his turn, he can forgo one of his attacks and use a bonus action to direct an ally that can see and hear him to strike using its reaction, adding the superiority die to the damage roll.

Rally. On his turn, he can use a bonus action and expend one superiority die to grant a friendly creature who can see or hear him temp HP equal to the superiority die roll + -1.

Brace. When a creature he can see moves into the reach he has with the melee weapon he's wielding, he can use his reaction to expend one superiority die and make one attack against the creature, using that weapon. If the attack hits, add the superiority die to the weapon’s damage roll.

Parry. When another creature damages him with a melee attack, he can use his reaction and expend one superiority die to reduce the damage by the number he rolls on his superiority die + 3.

Hero's Duty. When an ally he can see within 5 feet of him takes damage, he can use his reaction to take that damage, instead of the creature taking it. When he do so, the damage type changes to force.
