Eldritch Corruption

Those who are touched by eldritch powers whilst in the womb are subject to a phenomena known as eldritch corruption. Most individuals do not survive, and are miscarried before they come to term. Those that make it to birth are born with latent potential that can be realised at any point in their lives.

Eldritch magic can barely be comprehended by experts, and as such all attempts to replicate a corrupted individual's abilities have failed. They are observed closely however, by studies of the arcane nature.

Many would be terrified of the abilities of these sorcerers, and rightly so, as these abilities bend and pervert the rules of reality. As such, sorcerers who reveal these magical abilities tend to be feared, ostracized, and even hated.

Eldritch Knowledge

As your magic awakens, so does your mind. Strange knowledge comes pouring into you from a gap in reality, temporarily opened.

You gain proficiency in arcana and religion, if you are not already proficient. You can also choose one of your skills to gain expertise in.

Eldritch Magic

The magic that a sorcerer can learn can become tainted by eldritch energies, and twisted into incomprehensible, nightmarish forms.

You can learn a spell from the warlock list at levels 1, 5 and 10. These spells do not count towards your known spells.

You also gain Eldritch Blast as a cantrip, which doesn't count towards your known spells.

Eldritch Appendage

As the corruption spreads through your being, your form begins to mutate and change. The exact form this takes is different for every individual that is corrupted by eldritch energy.

A part of your body transforms into an eldritch appendage. Speak with your DM and agree upon the form that this will take.

As a bonus action, you can use the appendage to make an attack (melee or ranged). The attack deals 2d8 psychic damage on a hit, which increases to 3d8 at level 12. You are considered proficient in it's use, so you can add your proficiency modifier and charisma modifier to the to hit and damage.

You can use your appendage in this manner 1 + your constitution modifier times per long rest.

Ancient Wisdom

As the corruption spreads throughout your body, you begin to open your mind to the chaos down by the eldritch abominations that secretly hold dominion over the pockets outside of reality.

You can choose a skill to become proficient in.

Eldritch Dialect

Through repeated exposure to the eldritch corruption within you, your mind opens a step further, your thoughts leaking out and entering the minds of others.

You gain the ability to communicate telepathically with any creature within 100ft of you, and they can reply to these messages.

You also gain the spell command, and this spell does not count against your known spells.

Cataclysmal Flare

At this point, you are almost addicted to the eldritch energy that you house within you, instinctively drawing it en masse from razor thin gaps in the space between realities where your corruption was born.

As an action, you can release this pent up energy in a devastating blast. A line 10ft wide emanates from in front of you, travelling up to 100ft. All creatures caught within must make a Dexterity saving throw. If the target fails, they take 8d10 points of psychic damage, and are stunned until the end of their next turn. If they succeed, they simply take half of the damage with no other effects.

You can use this ability 1 plus your constitution modifier times per long rest. If you wish to use it further, you can use 3 sorcery points to convert 2d10 of your own health into another use of the ability.
