Monarch of Shadows

The Monarch of Shadows combines high martial mastery from the fighters with an innate ability with dark magic. The Monarchs of Shadows make use of their deadly martial prowess and obscure arcane capacities to fight and destroy their enemies. Although their unique abilities shine when dealing with the fallen enemies, as they extract their dark essence to create an army of creatures made of shadows that will follow their commands without any bit of hesitation.

Spellcasting

When you reach 3rd level, you augment your martial prowess with the ability to cast spells. See Spells Rules for the general rules of spellcasting for the sorcerer and the Spells Listing for the sorcerer, wizard and warlock spell list.

Cantrips

You learn two cantrips of your choice from the sorcerer, wizard and warlock spell list. You learn an additional cantrip of your choice at 10th level.

Spell Slots

The Monarch of Shadows Spellcasting table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these spells, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.

For example, if you know the 1st-level spell shield and have a 1st-level and a 2nd-level spell slot available, you can cast shield using either slot.

Spells Known of 1st-Level and Higher

You know three 1st-level sorcerer, wizard or warlock spells of your choice.

The Spells Known column of the Monarch of Shadows Spellcasting table shows when you learn more spells of 1st level or higher. Each of these spells must be of a level for which you have spell slots. For instance, when you reach 7th level in this class, you can learn one new spell of 1st or 2nd level.

The spells you learn every three levels must be of the necromancy school.

Whenever you gain a level in this class, you can replace one of the spells you know with another spell of your choice from the sorcerer, wizard or warlock spell list. The new spell must be of a level for which you have spell slots and can be of any school, unless you’re replacing the spell you gained every three levels, in which case must be from the necromancy school of magic.

Spellcasting Ability

Intelligence is your spellcasting ability for your spells, since you learn your spells through study, memorization and the magical surge flowing inside you. You use your Intelligence whenever a spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for any spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

Shadow Consumption

At 3rd level, you gain the ability to detect and manipulate the dark essence of the fallen creatures, creating shadow beings. You perform the ritual over the course of 1 hour, which can be done during a short rest. The creature must be within your reach throughout the ritual, at the conclusion of which you raise your hand and create a Shadow Servant.

The stats of the creature are replaced with new stats for the Shadow Servant, only retaining the creature's type along with the Undead type. Its appearance is that of a fully armored knight composed by shadows, emanating a bright blue glow in some parts of its body. The stats are as follows:

Presence of the Monarch

Beginning at 7th level, you gain proficiency in Intimidation checks, and when you have two or more Shadow Servants within 10 feet of you, gain advantage with the said checks.

At 15th level, you gain expertise with Intimidation, and depending on how many servants are near, you gain a bonus on your check:
-2 Shadow Servants: +1 bonus.
-3 Shadow Servants: +2 bonus.
-4 Shadow Servants: +3 bonus.

Shadow Recovery

At 10th level, you gain the ability to heal your Shadow Servants with dark magic before they are defeated. As an Reaction, you can fully restore the Hit Points for one of your Shadow Servants within 30 feet of you if their Hit Points are reduced to 0 or below. You can do this a number of times equal to your Intelligence modifier per long rest. 

At 18th level, the number of times per long rest are doubled.

Elite Army

Starting at 15th level, your Shadow Servants are strengthened thanks to the increase of your arcane power. You can now issue complex orders (guard a house in stealth, and attack any intruder that gets close to the bedroom), and decide the "type" of Shadow Servant when you create them: Shadow Infantry, Shadow Caster, Shadow Tanker, Shadow Scout, Shadow Assassin and Shadow Beast.

The number of the servants summoned at the same time now are doubled. Now it takes an Action to raise a Shadow Servant from a dead body within 30 feet.

The Monarch of the Shadows

Starting at 18th level, your mastery over the shadow arts is unparalleled. The CR of the creatures now can be equal or below your Fighter level and you can now decide whether to maintain the original creature as a Shadow Servant or create one type of the known servants.

Legendary creatures can now be turned into Shadow Servants, but you must roll a percentage to determine your succeess, depending on their CR:
-5 - 10: 30% or superior to succeed.
-11 - 15: 40% or superior to succeed.
-16 - 20: 50% or superior to succeed.

You can also turn only one creature with a CR of 21-24, but you must roll an 80% or higher in the d100 to successfully convert it into a Shadow Servant.
