Champion Knight

Brave. The champion knight has advantage on saving throws against being frightened.

Knight's Challenge. The champion knight can use a bonus action to challenge a foe within 30 ft. Any attack that the challenged foe makes until the end of the next turn that does not include the elite knight has disadvantage.

Indomitable (Recharges after a Short or Long Rest). The champion knight can reroll a saving throw that he fails. He must use the new roll.

Second Wind (Recharges after a Short or Long Rest). The champion knight can use a bonus action to regain 21 (1d10 + 16) hit points.

Multiattack. The champion knight makes three melee attacks with its longsword and one shield bash, if wielding a shield.

Longsword. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage or 9 (1d10 + 4) if used with two hands.

Shield Bash. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 9 (2d4 + 4) bludgeoning damage. If the target is a Medium or smaller creature, it must succeed on a DC 16 Strength saving throw or be knocked prone.

Heavy Crossbow. Ranged Weapon Attack: +5 to hit, range 100/400 ft., one target. Hit: 6 (1d10+1) piercing damage.

Leadership (Recharges after a Short or Long Rest). For 1 minute, the champion knight can utter a special command or warning whenever a nonhostile creature that it can see within 30 feet of it makes an attack roll or a saving throw. The creature can add a d4 to its roll provided it can hear and understand the champion knight. A creature can benefit from only one Leadership die at a time. This effect ends if the champion knight is incapacitated.

Riposte. The champion knight adds 3 to its AC against one melee attack that would hit it. To do so, the champion knight must see the attacker and be wielding a melee weapon. If the attack misses, the champion knight immediately as part of the reaction makes an opportunity attack against the opponent that missed.
