Warlock

Your patron is a mysterious entity whose nature is utterly foreign to the fabric of reality. Its motives are incomprehensible to mortals, and its knowledge so immense and ancient that even the greatest libraries pale in comparison to the vast secrets it holds. The Cosmic Terror might be unaware of your existence or entirely indifferent to you, but the secrets you have learned allow you to draw your magic from it.

Add the following invocations to your list of Eldritch Invocation options.

You have learned horrid methods of amplifying existing fears, and expose fears in people they did not know they had. You can use a free action to prevent a creature with the frightened condition from taking the attack, grapple, disarm, cast a spell, or dodge action while it remains frightened. You can use this ability a number of times equal to your spellcasting ability modifier.

Additionally, creatures within 10 feet of you have disadvantage on saving throws against spells and abilities you cast that apply the frightened condition, and you can use an action instead of a bonus action to target an additional creature with Psychic Leak.

You gain the ability to infect a humanoid's psyche with the mind-melting magic of your patron, a witness to the same existential torment you've endured up to this point. You can use your action to touch an incapacitated humanoid who is hostile towards you. That creature must make a charisma saving throw or be charmed by you until you use this feature again. Once this ability ends, the creature knows it was charmed, but cannot intuit who charmed it of its own volition.

While you and your thrall are on the same plane of existance, you can both communicate telepathically and gain immunity to psychic damage.

Once you use this feature, you cannot use it again until you finish a long rest.

Tireless efforts and peerless ambition; the untimely demise of the former cult leader; coincidence, happenstance or luck. The Cult cares not how you came to lead them. The only thing that matters now is you. You are their guiding voice. Their sheath. Their dagger.

You have made a pact with The Cult, and its followers—your followers—are everywhere. They work in secret, never revealing themselves—even to each other. Nobody knows which guard, merchant, or adventurer may be one of your cultists. One would be foolish to try and find out.

As a Warlock of The Cult, you gain the following features:

Add the following invocations to your list of Eldritch Invocation options.

You realise that you have a strange mask in your possession. It is branded with The Cult's sigil but you can't quite recall ever picking it up or where it came from.

Requires at least d10 cultists

As an action, you can sacrifice some cultists to perform a Cult Ritual. You can't use this feature again until you finish a long rest.

Requires d12 cultists

When you are killed, you didn't die—it was one of your cultists. The body disintegrates in a wreathe of eldritch flames. Which one of you is even real any more?

Roll your Cultists die once to determine how much of an impact this death has on The Cult.

Swap one of your language or skill proficiencies for a new one, then change one superficial, physical aspect about your character (such as the colour of your eyes, hair, or skin, the size of your nose, your stature, a scar on your face, and so on).

When your party reaches another village, town, or city, "you" may rejoin them.

Your patron is a lord or lady of the fey, a creature of legend who holds secrets that were forgotten before the mortal races were born. This being's motivations are often inscrutable, and sometimes whimsical, and might involve a striving for greater magical power or the settling of age-old grudges. Beings of this sort include the Prince of Frost; the Queen of Air and Darkness, ruler of the Gloaming Court; Titania of the Summer Court; her consort Oberon, the Green Lord; Hyrsam, the Prince of Fools; and ancient hags.

As a Warlock of the Fey, you gain the following features:

Add the following invocations to your list of Eldritch Invocation options.

Your patron teaches you how to turn the mind-affecting magic of your enemies against them. You are immune to being charmed, and when another creature attempts to charm you, you can use your reaction to attempt to turn the charm back on that creature. The creature must succeed on a Wisdom saving throw against your warlock spell save DC or be charmed by you for 1 minute or until the creature takes any damage.

As an action you may teleport up to 60 ft. to a location you can see.

You have made a pact with a fiend from the lower planes of existence—a being whose aims are evil, even if you yourself struggle against those aims. Fiends seek to corrupt, dominate, or destroy all things—including you.

Add the following invocations to your list of Eldritch Invocation options.

When you make an ability check or a saving throw, you can add a d10 to your roll. You can do so after seeing the initial roll but before any of the roll's effects occur.

You can use this feature up to three times. You regain expended uses when you finish a long rest.

Choose one damage type when you finish a short or long rest. You gain resistance to that damage type until you choose a different one with this feature. Damage from magical weapons or silver weapons ignores this resistance.

As a Warlock of the Greater Dead, you gain the following features:

Add the following invocations to your list of Eldritch Invocation options.

When you deal damage to a creature with a weapon attack or spell, you can use your reaction to mark the creature for death. The next time one of your greater skeletons deals damage to the marked creature, that creature takes an additional 2d6 necrotic damage.

You and your greater skeletons ignore resistance to necrotic damage and treat immunity as resistance. Additionally, when you roll damage for a spell you cast that deals necrotic damage, you can treat any 1 on a damage die as a 2.

As a Warlock of the Huntress, you gain the following features:

Add the following invocations to your list of Eldritch Invocation options.

Starting at 6th level, your patron grants you increased accuracy in exchange for your vitality. When you miss a ranged attack, you may spend a Hit Die and add it to the attack roll, potentially changing the result. Additionally, you may use your Unnatural Calm twice between rests.

Starting at 10th level, as an action you mark a creature you can see. The mark is removed if the creature is on a different plane, the creature dies, or you lose concentration (as if concentrating on a spell). Your next ranged attack against the marked creature automatically scores a critical hit. The projectile magically follows the target changing trajectory if needed and piercing through any barrier that can not be avoided.
