Characteristics

Charge. If the Spectral Knight moves at least 30 feet toward an enemy creature, it can immediately make a Hooves attack roll; the enemy creature must then make a DC 12 Strength saving throw or fall Prone.

Descycle. Upon being reduced to 0 hit points, the Spectral Knight must make a Constitution check with a DC equal to 10 or half the damage taken, whichever is higher. On a success, the Spectral Knight returns to 1 hit point; on a failure, it returns to its plane or place of origin. This effect doesn't trigger if it's destroyed by a source that interacts directly with the destruction of undead, such as "Liturgy: Destroy Undead" from an Acolyte of the Spiritual Rite.

Essence Devourer. When the Spectral Knight hits an enemy creature with an attack, the creature must succeed on a DC 10 Constitution saving throw or take 1 Necrotic damage and have its maximum hit points reduced by that same amount.

Mist Wraith. This undead is native to the Black Mist and is positively affected by it.

Mastery - Long Spear. The Spectral Knight is capable of using the Mastery (Push) property when wielding a Long Spear.

Object Manipulation. The Spectral Knight is capable of carrying and wielding equipment, and can add its proficiency bonus to attack rolls made with that equipment.

Disposable. The Spectral Knight takes double damage from failed-save effects or spells that aren't Strength-based. Even if the Spectral Knight succeeds on the saving throw to resist an effect or spell that isn't Strength-based, it takes damage normally instead of taking only half damage.
