Cursed Knight

Brave. The Cursed Knight has advantage on saving throws against being frightened.

Spellcasting. The Cursed Knight is a 5th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). The Cursed Knight has the following Paladin (Vegeance) spells prepared:

1st level (4 slots): bane, hunter's mark, searing smite
2st level (2 slots): hold person, misty step

Multiattack. The Cursed Knight makes two melee attacks with its Longsword. Alternatively The Cursed Knight can use the Abjure Enemy action and one of its melee attacks.

Longsword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage, plus 3 (1d6) necrotic damage.

Soul Whip. Melee Weapon Attack: +5 to hit, reach 30ft., one target. Hit: 5 (1d4 + 3) slashing damage, plus 3 (1d6) necrotic damage, and the target must succeed on a DC 14 Strength saving throw or be pulled up to 25 feet toward the Cursed Knight.

Abjure Enemy (Recharge 5-6). The Cursed Knight infuse the heart of its enemy with fear. One target within 60 feet of The Cursed Knight that can see it must make a DC 14 Wisdom saving throw, unless it is immune to being frightened. On a failed save, the target is paralized for 1 minute or until it takes any damage. If someone uses an action to shake the paralizated target or it takes a successful save, the target's speed is halved for 1 minute or until the target takes any damage.

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