Demonic Knight

The thing in unholy plate enters into the fray of the great church, the malice felt in his steps from miles away. The holy men run, but he cares not, for his grudge is not with them. One runs at him with a blade, a braver soul than most. His attempts are cut short, as the intruder swings with deadly proficiency, the large sword which just manifested in his hand decapitating with haste, as quickly as he entered. Striding forward, he flips the altar to the side, pressing down upon a hidden stone beneath, as the door behind him rumbles open. Coming down from the massive stone stairwell, he senses the new presence, sitting nearby. His target is here. As the stone defenders awaken to stop him, he cuts them down like they were the body with no head above. Shattering the adamantine chains, he bashes open the great stone container, setting his eyes upon the target. The blade is pleased.

Profane Warriors

Demonic Knights are some of the closest things there are to an “anti-paladin”. Bound in service to a lord of the lower planes, they are their will upon the material realm. In return for their service, they are granted a weapon of untold power, and the magical powers to supplement it.

Creating a Demonic Knight

When creating a demonic knight, think about how you became one? Were you born in the lower depths of the infernal realm, born to serve a demon lord? Did you make a pact with a demon, promising your soul for greater power? Or perhaps your dark powers came from an unknown source, lying dormant in you until an unspecified time?

Quick Build

You can make a Demonic Knight quickly by following these suggestions. First, Strength or Dexterity should be your highest ability score, followed by Charisma. Second, choose the soldier background.

Demonic Weapon

You have a unique sentient magical weapon called a Demonic Weapon bound to your soul. A Demonic Weapon can take the form of any melee weapon or ranged weapon (with the exception of firearms). The weapon has Intelligence, Wisdom , and Charisma scores of 10. It communicates by transmitting emotions to its user(joy-sadness, anger-fear, trust-distrust), can perceive up to 30 feet away, and only you can hear it; others merely hear ghostly whispers from the weapon.

The Demonic weapon gains a +1 bonus to attack and damage rolls, which increases by 1 at 9th level (+2), 13th level (+3), and again at 18th level (+4). Starting at 11th level, a Demonic Weapon deals extra necrotic damage equal to the weapon's damage die whenever you hit with it. You may also divide your demonic weapon into two smaller weapons (both must have the light property) that can be dual wielded, but their magic bonus is cut in half and the offhand weapon does not gain the extra damage dice (from levels 11 and 20).

Your Demonic Weapon can't be damaged while you are alive. If your Demonic Weapon ever leaves your hand, you may summon it back into your hand as a bonus action, and you can make it disappear as a free action. The Demonic Weapon does not count against your maximum attuned item count. The weapon's form can be changed during a long rest to that of another melee weapon.

Unholy Resurrection

Unholy Resurrection: When you slay a creature with your demonic weapon or with a spell, you may use your reaction to raise that creature as an undead version of itself. The creature changes in the following ways:

  • The creature's hit point maximum is reduced by half.
  • Gains vulnerability to radiant damage, and loses any resistances.
  • Creature is incapable of rational conversation or thought, and it obeys your every order.
  • During Combat, the undead under your control acts on your turn. You may use a bonus action to command them to attack or take an action. Otherwise they will remain still.
  • Any weapons and Basic actions it knew how to use in its previous life it can still use (Flying, Swimming, Climbing, etc), but more biologically complex actions such as breath weapons are up to the DM's discretion.

You can raise up to three creatures, but their combined total CR cannot be greater then 1/2 your Demonic Knight level. You cannot raise constructs or re-raise undead. Note that this CR limit does not include undead raised by other sources, such as animate dead.


Beginning at 2nd level, you can augment your martial prowess with spells. You can cast spells from the Demonic Knight spell list. At 2nd level, you know two cantrips of your choice from the Wizard spell list. You learn additional wizard cantrips of your choice at higher levels, as shown in the Cantrips Known column of the Demonic Knight table. Charisma is your spellcasting ability for your spells. Your Demonic Weapon is considered your arcane focus.

Demonic Order

A Demonic Knight's aspirations often rise far higher then their current stature. Typically they follow an order that will ultimately lead to the destiny they desire most. At 3rd Level, choose one of the following Archetypes as your Demonic Order: Harbinger of Destruction, Lord of the Undead, or Dark Emperor. You gain features in this archetype at 3rd level, and again at 7th, 11th, and 17th level.

Ability Score Increase

When you reach 4th level, and again at 8th, 12th, 16th and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Extra Attack

Beginning at 5th level, you can attack twice, rather than once, whenever you take the Attack action on your turn.

Dark Fury

The demonic rage inside you allows you to ignore certain debilitating effects. At 6th level you gain immunity to disease and the frightened condition.

Demonic Essence

Your Experience as a Demonic Knight has heightened your physical constitution and mental faculties. At 9th level you gain resistance to poison as well as gaining 60 feet of darkvision. Should you already have darkvision, you gain an 30 extra feet instead.

Eldritch Armor

You have learned to use arcane magic to enhance your defenses. At 14th level you can use a bonus action to choose between cold, fire, lightning, necrotic, or radiant damage. You gain resistance to the chosen damage type. You may change the resistance type by using a bonus action on another turn.

Aura of Vengeance

The hatred of your enemies permeates the air as an ominous aura. Once per long rest as an action you may exude an aura of malice in an area 30 feet around you. Creatures who enter or start their turn in this field must make a Charisma saving throw against your spell save DC. On a failed save they are marked for vengeance and take 2d8 necrotic damage, or are not marked and take no damage on a successful one. While you attack a marked creature with your Demonic Weapon you gain a +3 bonus to attack and damage rolls. A creature is marked for one round before the effect wears off, and the creature must make the saving throw again.

King of Darkness

You are feared throughout the land as the embodiment of darkness. At 20th level Dark Magic now pulses through your body as you gain the following benefits

  • You sprout a pair of massive wings. You gain a flying speed equal to your base movement speed.
  • Your maximum amount of hit points increase by 30. Your Demonic Weapon also gains an extra damage die (necrotic as well).

Demonic Orders

Harbinger of Destruction

Demonic Knights who focus their dark energies into enhancing their physical abilities, Harbingers of Destruction spread havoc across the battlefield. Those who follow this order tend to work alone, decimating hordes with blows that hit multiple targets: friend and foe alike.

Bringer of Chaos

Upon choosing this demonic order at 3rd level, your blows start wreaking havoc on the battlefield. When attacking a creature with your Demonic Weapon, as a bonus action you unleash dark energy form your weapon.. Other creatures within 5 feet need to make a Dexterity saving throw against your spell modifier. On a failure they take 1d8 necrotic damage , or half as much on a successful save (This damage becomes 1d4 for a ranged weapon attack). You may use this feature a number of times equal to your proficiency bonus, and you regain all uses of this feature at the end of a short or a long rest. The damage increases to 2d8 (2d4 for ranged weapons) at 14th level.

Arsenal of Devastation

Your collection of demonic weaponry expands. At 7th level you may now spend 10 minutes instead of a long rest changing the form of your Demonic Weapon. In addition, if your demonic weapon requires ammunition, it can magically create a piece of ammunition that disappears at the end of your turn. This ability can be used a number of times equal to your Demonic Knight Level.

Overwhelming Power

Your blows decimate the defenses of your enemies, and you can more easily hit their weak points. At 11th level your Demonic Weapon now scores a critical hit on rolls of 19-20.

Ultimate Annihilation

At 17th level the destruction of your enemies is now absolute. At 17th, once per short or long rest when you defeat a creature with your Demonic Weapon, you may use your reaction to cause them to explode in a burst of dark energy. Creatures within 15 feet must make a Dexterity saving throw against your spell modifier or take 4d10 necrotic damage, or half as much on a success. You may use this ability one more time for each creature defeated with a critical hit.

Lord of the Undead

Unnatural Constitution

Upon choosing this Demonic Order at 3rd level, you are able to raise the undead in better condition. The undead you control now have their maximum hit points reduced by one-quarter as opposed to one-half.

The Dead Shall Rise

At 7th Level your experiments with controlling the undead have allowed you increase the numbers of your horde. The number of undead you can control through "Unholy Resurrection" increases by two. In addition the undead you control regain any resistances they had while they were alive.

Soul Inheritor

You believe the undead hordes should serve you and only you. At 11th level as an action you can attempt to take control of an Undead whose CR does not exceed your maximum total. That undead must make a DC 13 Charisma saving throw against you. If the undead is controlled by another necromancer, the target makes the saving throw with advantage. Should it succeed, it does not fall under your control and is immune to further attempts at controlling it. Otherwise the undead falls under your control. You may use this ability a number of times equal to your proficiency bonus per long rest.

Master of Souls

At 17th level your command of the undead reaches even greater heights as you are able to control even more powerful undead. The maximum CR of undead you may control is now equal to 3/4 of your Demonic Knight level.

Dark Emperor

Acolyte of the Dark Arts

Your experience training in the dark arts has altered your fighting style. Upon choosing this demonic order your Demonic Weapon can now fire bolts of darkness (30/60 range) as an attack action that deals 1d10 necrotic damage. This attack uses your Charisma modifier for hit and damage rolls. The damage increases to 2d10 at level 14. When you would gain the ability to make more than one attack, like the Extra Attack feature, you can replace any number of these attacks with instead firing a bolt of darkness.

Terrifying Fiend

You excel in terrifying the masses. At 7th level you gain proficiency in Intimidation. If you already have proficiency, you may double the bonus. In addition, demons summoned by spells are always loyal to you (summon lesser demons is an example of such a spell).

Arcane Secrets

At 11th level your research into the arcane has revealed new knowledge. Choose three spells off of the wizard spell list of 1st or 2nd level. You learn these spells, and they do not count against your spells known. In addition, you may now store a single charge of a 1st or 2nd level spell in your Demonic Weapon, which may be unleashed without using a spell slot (it must be cast at its base level). This feature can be used once per long rest.

Supreme Demon

At 17th level your power commands the respect and loyalty of the creatures of darkness. You have gained the loyalty of two Undead Knights who will follow your every command.
