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

Born to the Saddle. The knight has advantage on saving throws made to avoid falling off its mount. If the knight fall off its mount and descends no more than 10 ft., it can land on its feet if not incapacitated.Finally, mounting or dismounting a creature costs the knight only 5 feet of movement, rather than half its speed.

Lancer. The knight was advantage on attacks made with its lance, if the knight is mounted.

Couched Lance Attack. If the knight is mounted and has moved at least 30 ft. in this round, it deals an additional d12 piercing damage with lance attacks and an additional d12 made with lance attacks per additional 15 ft. moved over 30 ft. the knight has moved this round up to a maximum of 6d12 additional damage. If the knight has moved more than 60 ft. in this round there is a 25% chance the lance will break per attack made. 

Multiattack. The knight makes two melee attacks.

Lance. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 9 (1d12 + 3) piercing damage. Disadvantage on all attacks made while dismounted.

Arming Sword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage.

Light Crossbow. Ranged Weapon Attack: +3 to hit, range 100/400 ft., one target. Hit: 4 (1d8) 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 3 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.
