Undead Savant

There are those who are more adept with communicating or even controlling the dead and the undead. Those whose lust for magical power allows them to push past the ridiculous concept of morality. Dead bodies are useless if not put to work, simply a waste of space to create entire graveyards. So much time and effort is spent making the graveyards, you find it much easier to use the undead to your advantage.

Command Undead

At 2nd level, you have begun to learn how to bend undead to your will. As an action, you can impose a 8 + INT mod + proficiency bonus WIS Saving Throw on an undead within range. If the undead has a INT score of 10 or more, it has advantage on this roll. On a failure, you can tell them which way to move telepathically and how they use their action. Any other actions that the undead has such as reactions, bonus actions, or other abilities are unavailable to you. You can only control a number of creatures equal to your proficiency bonus at one time. If you would go over that limit, the creature with the lowest time left on their timer is released from your control.

At 14th level, this limit goes up to double your proficiency bonus.

Aura of the Grave

At 2nd level, those who can sense magic identify you as an undead. In addition to this, undead with an INT score lower than yours cannot identify you as a non-undead. When an undead with an INT score lower than yours makes an attack against you they must make a 8 + INT mod + proficiency bonus INT Saving Throw or change their attack target. All undead you control within 30 feet of you have +2 to AC and have resistance to all damage except psychic. In addition, any undead that you control do not have any vulnerabilities. 

Create Undead

At 6th level, you gain the ability to use creatures to your advantage even after they die. As an action, you can reanimate 3 creatures near you and they come back as an undead with a CR equal to 1/3 your character level. They share an initiative with you and go right after you. You can use this feature a number of times per long rest equal to your proficiency bonus. Creatures affected by this only last for 10 minutes until the turn back into corpses.

At 14th level, you can use this feature a number of times per long rest equal to double your proficiency bonus.

Summon Undead

At 6th level, you can use your action to summon an undead with a CR equal to your character level + 1. You can use this feature a number of times equal to your proficiency bonus per long rest. This creature shares an initiative with you and goes right after you. You can only summon 1 undead at a time with this feature. Any creature summoned by this feature is destroyed during a long rest.

Banish Undead

At 10th level, you gain the ability to banish undead completely. As an action, you can impose a DC 8 + INT mod + proficiency bonus CHA Saving Throw or be banished to the Psyche Plane. The Psyche Plane is a plane inside of your mind in which a creature cannot use any method of escape. The only way for a creature to escape this plane is to have the creature whose Psyche Plane they are trapped in die. The creature that owns the Psyche Plane can release any creature trapped within their Psyche Plane whenever they desire. Once a creature dies, their Psyche Plane ceases to exist, putting any creatures trapped within their Psyche Plane back into the Material Plane. Any creature with a CR lower than your character level has disadvantage on the Saving Throw and any creature with a CR equal to 1/2 your character level automatically fails the Saving Throw. Any creature with a CR equal to or higher than your character level has advantage on the Saving Throw. If a creature has a higher INT score than you, they automatically succeed the Saving Throw. You can use this feature a number of times per long rest equal to your proficiency bonus.

At 14th level, you can use this feature on any creature type.

Undead Savant

At 14th level, you have mastered the ability to control the dead. All undead creatures you control have x2 their max HP, have resistance to all damage, have immunity to Necrotic and Poison damage, deal double damage dice with all weapon Attacks, have advantage on all saving throws, and have a +4 to AC. There is no limit to the amount of creatures you can control with Command Undead, there is no more limit to your Create Undead, and you can control as many creatures as you are able to summon with Summon Undead.

As an action, you can summon a number of undead creatures up to your proficiency bonus with a CR of 1 or lower.
