Ashen Creature.

When the knight drops to 0 hit points, it is reduced to a pile of ash, and any equipment it was wearing or carrying falls to the ground.

Brave.

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

Actions

Multiattack.

The ashen 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 ashen 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 ashen knight. A creature can benefit from only one Leadership die at a time. This effect ends if the ashen knight is incapacitated.

Reactions

Parry.

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