Multiattack. The knight makes two melee attacks.

Heavy Crossbow. Ranged Weapon Attack: +2 to hit, range 100/400 ft., one target. Hit: 5 (1d10) piercing damage.
Leadership (Recharges after a Short or Long Rest). For 1 minute, the knight can utter a special command or warning whenever a nonhostile creature that it can see within 30 ft. 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 knight. A creature can benefit from only one Leadership die at a time. This effect ends if the knight is incapacitated.

Parry. The knight adds 2 to its AC against one melee attack that would hit it. To do so, the knight must see the attacker and be wielding a melee weapon.
