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

Spellcasting. The knight is a 1st-level spellcaster. Its spellcasting ability is Charisma (spell save DC 13, +4 to hit with spell attacks). It has the following sorcerer spells prepared:

Cantrips (at will): fire bolt, mending, prestidigitation

1st level (2 slots): burning hands, disguise self, shield

Multiattack. The knight makes two melee attacks.

Greatsword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage.

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 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 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.
