Hungering Soul

You have found that your soul alone is not enough for the spell casting you are capable of so you have turned to consuming and using the souls of other creatures. Your body is a vessel that expands as you grow in power. Though you start off only able to hold a few spirits inside of you, you learn to hold and use these extra souls to your advantage.

Pull back the Curtain

As you let go of the façade you've created to hide your true appearance the spirits within you pulse out of your body reaching for the nearest empty vessel to inhabit. This ghostly display is traumatizing to most living creatures causing them to be wary of you as they fear you may consume them as well.

Consuming Touch

Your soul hungers so much that your body becomes an instrument of its hunger when you touch those who have a soul their body burns and is marked with no save. This mark is considered a curse and can be removed through the normal means of removing curses. Though the mark remains and the voices of the spirits you hold speak to the marked at times asking for help.

Soul Container

Your body is a container and is able to survive the strain of souls trying to affect your mind and body, though you are limited to what your power allows you to do. You start at level 1 only able to hold 5 souls and each level you add 5 more souls to your cap. You are able to hold more souls than your cap for a short period of time but for each soul that you go over, you take 1d6 necrotic damage at the start of your turn in combat (You are unable to maintain concentration and may choose to use your action to focus and not take damage that round) or once every minute outside of combat due to your ability to focus more energy on containing the soul.

Spirit Scream

The spirits within you shout for freedom but only you can hear these voices unless you amplify their voices to those around you. You amplify the voices within you causing a wave of powerful energy to emit from you which causes 1d10 thunder damage to those who can hear and 1d4 necrotic damage to anyone who is deafened. Consumes 10 souls

Soul Wave

You release an immence number of souls to form a wall with grasping arms and gnashing teeth. As the wall travels forward the arms grab and take hold of enemies and throw them back 15 feet while also dealing heavy damage to them. Enemies often are left with scars after being hit by the wall. You can spend 2 sorcery points to cause all enemies hit by the wall to be marked.

Impart Soul

You take the souls in your body and impart them into dead bodies around you allowing them to rise from the dead and become faithful members of your party. These members are able to speak common and any language you know and are able to be commanded telepathically. The amount of souls required to summon an undead is equal to 4 x the CR of the dead creature. (Yes you can summon dragons if you have enough souls)

Conquer Undead

You seek to take the power of another necromancers undead into your own hands by forcing some of your hard earned souls into the undead. You place your hands on the undead and force the dark magic out and push in a proper soul that places the undead under your command. This follows the same rules as impart soul and requires the same number of souls based of the CR of the creature.

Achieve Lichdom

Death is for mere weaklings. Your name has become a synonym with death and you have learned the arts of creating phylactories that allow you to survive anything that is thrown at you. Nothing short of a Wish spell can kill you and even that only has a 50% chance of success. (If wish spell attempt is made roll a percentage die and if below 50 the wish fails if above the wish succeeds) You can only be slain if your phylactory(s) is/are destroyed. Then and only then can you be slain. You are allowed multiple phylactories but you can only create one every 100 years as even the gods cannot fathom such energy to create multiple in quick succession.

Spiritual Restoration

Your mastery of the dark has brought out the light and allows you to give life as well as take it. You can place your hand on a creature imparting some souls into them which cause the person to feel restored. You can mark and restore a creature at the same time. If 5 or more souls are used to heal someone you can choose to remove all diseases and exhaustion from the person. Lycanthropy is unaffected by this as it is both a disease and a curse.
